ZythyrQuestion: I am installing Ubuntu in BIOS (legacy mode). My first partition is 550MB and I marked it as "Reserved BIOS boot area". No I need to have a "bootable" flag "On" for this partiton? Yes I know for BIOS bios grub 550MB is more than enough, but I kept it at 550MB becasue I plan on migrating to EFI in the future.00:09
TJ-Zythyr: for BIOS Boot you only need at most 2MB :)00:16
TJ-Zythyr: and no it doesn't need a bootable flag, in fact, with GPT, there is no such thing although if you're creating a hybrid MBR that also maps that partition then the MBR can have it's boot flag set00:17
ZythyrTJ- Im doing BIOS with GPT partition scheme. In Gparted, My first partition is 550MB and I put "bios_grub" flag on it. But before installing Ubunut, its asking me if I want to put "bootable" flag on it. I did 550MB because in the future I will be doing EFI instead of BIOS00:17
TJ-Zythyr: if you can plan on having EFI later, then just create both an EFI System Partition of about 512MB and a 2MB BIOS Boot partition00:17
ZythyrOhh okay. So if I am doing GPT then bootable flag not need00:18
ZythyrSo the 2MB boot partition needs to be before the EFI System Partition?00:18
TJ-Zythyr: here's what I use: https://paste.ubuntu.com/26486498/00:18
TJ-Zythyr: as long as the BIOS Boot partition is near the start of the disk the order doesn't matter00:19
ZythyrTJ- Thanks for the share. I did similar but I didn't create teh "BIOS boot partition" of 8MB. I created a 550MB partition and called it "EFI System System" even though I am using it as BIOS boot partition. Is that fine?00:26
TJ-Zythyr: well it means you can only do either/or. With my way you can do both and so choose which mode to boot in00:27
ZythyrOhh I didn't know both options were possible. I already started install of Ubuntu server. Is it possible to fix it after installation?00:28
dingirwhats the purpose of encrypting my home folder00:28
dingirif i want more security i should encrypt / too ?00:29
ZythyrAnd when you say choose either/or, how do you choose if u want to BIOS or EFI method of booting?00:29
TJ-Zythyr: all you need to do is partition it so both partitions are there; you can do the additional GRUB work later to have both types of boot available00:29
TJ-dingir: encrypted home means that even if the PC is booted, your personal files cannot be read unless your user is logged in00:30
TJ-dingir: whereas Full Disk Encryption protects the complete OS when it's NOT running (e.g. if the system/disk were stolen)00:30
Zythyrdingir Encryption is good if you don't want anyone with physical access to your hard drive to be able to read your data. For example, if your PC gets stolen, even though you may have a strong login password, the theif can use a live USB and read your data00:31
ZythyrTJ- Is your system configured so it automatically detects if your PC supports EFI boothing and if it then it boots to EFI and if not then BIOS?00:32
mattflyhello everyone, ive recently updated my ubuntu 16.04 lts using a nvidia gpu (laptop), but i got some problem trying to reboot and im unable to see my system GUI, right now im on recovery mode, the error is "bbswitch not suitable _DMS call found00:32
mattflywth is that how to get the gui back?00:32
TJ-Zythyr: no, it's configured so I can choose at boot-time, in the firmware's boot menu, which type of boot I want00:33
mattflyand my connectyion sucks00:33
TJ-mattfly: is this of any help? https://askubuntu.com/questions/857816/my-drivers-recognize-my-graphics-card-but-nvidia-settings-do-not00:34

dingirbut if only /home is encrypted its secure too if hard drive gets stolen as in no one can read the data00:36
dingircan i encrypt /home if system already installed?00:36
TJ-mattfly: also this ubuntu forums post about 16.04 and kernel upgrades seems more relevant. Try booting to an earlier kernel version via the GRUB boot menu > Advanced sub-menu. https://ubuntuforums.org/showthread.php?t=237205600:37
iulian_anyone can check please qdbus org.mpris.clementine00:37
iulian_Service 'org.mpris.clementine' does not exist.Why ?00:38
TJ-dingir: it's not /home/ that is encrypted, it's /home/$USER/ and yes, it's also protected if the device is stolen. It doesn't protect against someone being able to insert malware if they have physical access to the powered-off PC though00:38
Zythyrdingir I recently researched about encryption. I dected to encrypt my entire home partition instead of just /home/myusername. These two articles will be a good read for you 1) https://wiki.archlinux.org/index.php/Disk_encryption and 2) https://help.ubuntu.com/community/ManualFullSystemEncryption00:41
Zythyr^ the second article if for block device encryption compared to this artcile which is just to encrypt your /home/userusername folder 3) https://www.howtogeek.com/116032/how-to-encrypt-your-home-folder-after-installing-ubuntu/00:42
Guest65Hi there, I was wondering if anyone else has had success getting Ubuntu running on a MacBook Pro Mid-2015, and if they have seen any major performance degradations00:46
ZythyrTJ- When you say firmware's boot menu, you mean like the BIOS menu if u want to boot in UEFI mode or Legacy mode?00:47
TJ-Zythyr: if it's using EFI then it's not BIOS :) BIOS and UEFI are firmware, UEFI manual boot menu usually offers the option to boot in UEFI mode via entries in the firmware's own memory, or via Compatibility Support Module (CSM) in BIOS mode for a specific device.00:49
ZythyrTJ- Ubuntu server is asking me if I want to install GRUB boot loader. Do I choose "/dev/sda" or do I choose "/dev/sda1"? Assuming my configuration was like yours where my sda1 was BIOS boot partiiton and sda2 EFI, then what would I choose?00:49
TJ-Zythyr:  /dev/sda00:50
lordcirthZythyr, Grub always goes on the drive00:50
TJ-Zythyr: GRUB figures out where to put it's core image and boot files, and write it's own config00:50
TJ-!mactel | Guest6500:51
ZythyrSo always choose the drive? Not the partition (ex: sda1)00:51
TJ-!mac | Guest6500:51
ubottuGuest65: For help on installing and using Ubuntu on a Mac, see: https://wiki.ubuntu.com/MactelSupportTeam/CommunityHelpPages00:51
TJ-Zythyr: yes00:51
TJ-Zythyr: unless you're doing something /very/ special and experimental00:51
Zythyrohh okay00:52
Guest65thanks ubottu00:52
ZythyrTJ- If I configure my partitions like yours, do I still mark sda1 (BIOS) as "bios_grub" partition in Gparted? And during installation mark it as "Reserved for BIOS boot"? As for the EFI partition, I won't be able to mark it for "EFI" becasue my system doens't hhave EFI so ubuntu doesn't even give me option to mark it00:54
TJ-Zythyr: Yes, mark sda1 as bios_grub ... create the EFI SP as any other type - the only important part is to reserve the space. Once the OS is installed and booted you can change the partition type00:55
ZythyrOhh okay. And the sda1 partition will be "unformatted" right? And  the EFI parittio nas Fat32? Once I am done with installation of Ubuntu, I can mark the EFI partition as EFI? But do I need to do some configurations of grub after this?00:57
TJ-Zythyr: yes, sda1 is unformatted. GRUB writes it's core image directly into that partition using grub-install00:57
ZythyrOhh okay great! THanks for the clearifcation.00:58
ZythyrI think I am going to scratch the current install and restart.00:59
Zythyrand do the partition scheme like yours00:59
TJ-Zythyr: after installing/booting in BIOS mode there is a bit of a dance to do to install the grub-efi - The way I do it is create a Virtual Machine that boots in EFI mode, attach the real hard disk to it as (/dev/sda) and a VM disk image file (e.g. /home/tj/diskimage.bin ), attach the installer ISO image as a DVD device to the VM, and boot. During EFI install I install the OS to the disk-image file but set01:01
=== Fireman_Ed is now known as FiremanEd
TJ-the boot-loader device to /dev/sda so it uses the EFI system partition.01:01
ZythyrAhh so u trick it into installing grub on /dev/sda01:02
ZythyrGood to know that01:02
ZythyrI think for now I will have partition scheme like your, but not touch the EFI System Partition. If an when I move to a system that is UEFI based, then I will worry about fixing the EFI system partition. But for now I will have the partition there as making it future proof01:03
TJ-Zythyr: I then shutdown the VM, delete the disk-image file, mount the EFI SP into the current running OS ("mkdir -p /boot/grub/efi; mount /dev/sda2 /boot/grub/efi") and copy the grubx64.efi to the EFI removable media path so I can boot in EFI mode without an entry in the firmware's boot menu (EFI boot via the device name) with "cp /boot/grub/efi/EFI/ubuntu/grubx64.efi /boot/grub/efi/EFI/boot/bootx64.efi"01:04
TJ-Zythyr: finally!! once rebooted in EFI mode, I just run "sudo grub-install /dev/sda" and it redoes the install but also calls efibootmgr to add Ubuntu to the firmware's boot menu01:05
TJ-Zythyr: in reality, I pull a lot of tricks and don't do it that way, but I'm a GRUB hacker so I know how to short-circuit things, but if I told you that process you'd get hopelessly lost :)01:06
stockLinux kernel Version 4.4.0-111.134~14.04.1: contains a truckload of changes related to "speculative execution"    Does this boot or even run ?01:11
ZythyrTJ- hahha thanks for the clearification after the VM install trick. Or else I would have been lost lol01:12
ZythyrTJ- Here is my setup. Apparently in Gparted I had the ESP option. I am unsure what will happen when I do Ubuntu Server install and when it installs GRUB. Maybe it will configure for both BIOS and EFI??? https://imgur.com/a/i2GGc01:13
TJ-Zythyr: installer will only install GRUB in the same mode the installer booted in. So if installer starts from EFI mode it'll install grub-efi in EFI SP,if booted in BIOS/CSM mode it'll install grub-pc to the BIOS Boot partition01:17
TJ-Zythyr: this is why we have to 'dance' to do both01:17
Zythyrahhh now i understand what u mean01:18
TJ-The problem is, if booted in EFI mode we /could/ install for both EFI and BIOS mode, but if booted in BIOS mode there's no access to the EFI variables so we cannot install an EFI boot menu entry, which means there'd be no access to the installed OS on reboot01:21

=== hidari is now known as nicedreams
ZythyrTJ- if booted in EFI mode, how do I install for both EFI and BIOS? The reason I ask is becasue I can attached the HDD to a PC that boots into EFI mode and then do Ubuntu install from there01:38
stocklooks like a very nasty job nicely done : https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SpectreAndMeltdown01:39
TJ-Zythyr: you'd install in just EFI mode as usual (with the EFI SP and BIOS Boot partitions), reboot into the OS, then do some clever stuff with installing the grub-pc-bin/grub2-common/grub-common but *NOT* the grub-pc package (because grub-pc would cause grub-efi and the other grub-efi-x86_64* packages to be removed)01:43
TJ-Zythyr: there's a better way than that though, which is to create an LXD container with /dev/sda mapped into it and install just the grub-pc package.01:44
TJ-Zythyr: I really ought to write-up all these methods because they look much simpler when you see just the commands without the long-winded explanation01:45

TunaLobsterHey guys. Hitting an issue today on 14.04 LTS (using for legacy software support). The issue comes up when a python (2.7) portion of a script is writing to disk. It's somewhere between blitz++, python2, and mpirun. I'm not able to reproduce outside of this program right now. Apt update history shows nothing changed since last known working run of this program.01:53
TJ-weaksauce: does ./test exist for find in the script to find ?01:53
weaksauceit does TJ-01:53
TJ-weaksauce: so is the issue all those logical-ORs because that's very different from the single shell command above01:54
TJ-weaksauce: think about your "-name *.sh" clauses; what is going to process those * ? It'll be the shell won't it?01:55
weaksauceTJ- reading the man page it seems like that shouldn't be an issue with the -exec \; version as it serially sends it to sed.01:55
TJ-weaksauce: you need, I think, "-name '*.sh'  " - single quotes around them01:55
TJ-weaksauce: you want find to handle the * not the shell01:55
weaksauceTJ- ah. i will try that01:55
weaksauceTJ- no dice. no error just no editing of the file01:58
weaksauceTJ- https://gist.github.com/anonymous/ca2bd1bc4a30e9b351d8e7334e8f74ab01:58
weaksaucethat is a more complete picture as the other one was edited a bit01:58
TJ-weaksauce: does the command return file names for sed to process?01:58
weaksaucethe first find does in fact print them out yes01:59
weaksaucethere are two finds with almost identical predicates01:59
TJ-weaksauce: try this, I did something like this earlier for someone else: "... -exec sh -c "sed -i -e '$SUB' {}"  \; "02:01
weaksauceTJ- tried a few variants of that and nothing is giving an error but it's not doing anything02:07
unomasbeerne1 have any really good fonts for coding02:07
TJ-weaksauce: hmmm, if you remove the -exec it does print out the file names that matched?02:09
TJ-weaksauce: I'm wondering if this is due to running under zsh. Have you tested it with other shells?02:10

weaksaucemaybe i can use xargs and pipe it02:13
TJ-weaksauce: OK, I see your problem. You need to surround your logical or's with \( .... \)02:20

roadrunneratwastthen maybe i can just chop off the end of the windows partition and format it as ext405:32

jusssthe login page belong to gdm I think05:41

causativeI have been having a problem since updating from 17.04 to 17.10:  first of all, it's using more memory than it used to and not using any swap, and second of all, as soon as it runs out of application memory the system hangs for ~15 minutes and when it recovers dmesg is full of page allocation faults07:44
causativeI have 4 gigs of memory and the last hang occurred when i just was playing 2 videos in firefox and almost nothing else07:45
Ben64causative: pastebin the output of 'free -m'07:45
causativeright now it's ok, when it comes out of the hang it has used some swap, but it does not use swap during normal operation07:46
causativeI know it occurs when the available memory runs out because I have a status bar widget showing the amount of application memory07:47
causativeand every time it hangs, the widget shows all memory used07:47
causativeand during normal operation it does not show all memory used07:47
Ben64sounds kind of normal07:49
Ben64if you run out of memory, you'll experience bad things07:49
causativeit should be using swap instead of hanging for 15 minutes07:49
Ben64it is using swap07:49
causativeand it is using too much memory as well for what it's doing, compared to 17.0407:49
causativeI just said it's not using swap during normal operation07:49
causativethis is after the hang07:49
causativeif I booted it up clean, it would use all 4 gigs of memory and 0 swap, then hang07:50
causativefrom just browsing the web07:50
Ben64browsers take lots of memory07:50
causativeit's obviously not normal07:50
=== bat is now known as Guest28637
Ben64what's the output of 'cat /proc/sys/vm/swappiness'07:51
dingirhi i have a question07:51
Ben64then it's set up normally. don't run out of memory : /07:52
Ben64use something like htop to see what's eating it all, and take care of it07:52
causativeit's obviously not set up normally since it was not happening before and it's not using swap!07:52
Ben64but it is using swap...07:52
causativeI already explained that to you07:52
Ben64it's using swap because it ran out of memory, that's literally what swap is for07:52
causativemy widget shows swap as well as memory and at the time of first hang since boot it will always show 0 swap used07:52
causativeit should not hang for 15 minutes or come back with 4000 lines of page allocation faults in dmesg, it should just transfer some things to swap07:53
Ben64it can't always do that07:53
causativewhy not?07:53
causativeI have an SSD, swap should be fast07:53
Ben64because things need to be in memory to be used07:53
harindu_there is a variable ( i don't remember which one) which determines the swappiness07:53
dingirif i encrypt my home folder, am i more subject to increase failure of filesystem or having it not fixable after power outtage and stuff like that?.. is it more likely for an encrypted partition to give problems when checking filesystem after unexpected shutdown.. is it harder to fix than non encrypted?07:54
harindu_if it's zero it doesn't swap even it's out of memory07:54
causativethere's no reason for it to need 4 gigs of memory to play 2 videos in firefox07:54
causativeit did not used to need that07:54
Ben64harindu_: yep checked that, it's at the default value of 6007:54
Ben64causative: you should check htop07:54
causativeit tells me firefox is using the memory07:55
causativegnome-shell at second place with 243 MiB07:55
causativefirefox at 397.4 MiB and some Web Content processes at 208, 143, 130, 105 MiB07:56
causativedoesn't seem like it ought to add up to 4 GiB, but apparently there are a lot of smaller processes that add up07:56
dingirwhat algorith for encfs?07:56
causativebefore closing firefox just now it was using 2200 MiB, now it's using 1573 MiB and I have nothing open but some terminals, emacs and xchat07:58
causativeis it normal for 17.10 to use over 1 GiB of memory immediately after boot with nothing open?08:04
=== leion1 is now known as leion
auronandacecausative: i'm on 17.10 and it is using around 800mb. got thunar, cmus, htop and weechat running08:10
auronandacecausative: i'm using i3 though rather than a desktop environment like gnome08:10
auronandacecausative: also dropbox is running in the background08:12
=== leion1 is now known as leion
causativeso 1.1 GiB on boot may not be too abnormal if gnome-shell is a beast, maybe part of my problem is some memory leak in firefox or noscript08:13
causativebut it still should not be hanging 15 minutes the first time it reaches full memory, there should be plenty of inactive memory that can be swapped the first time it hits the limit08:14
auronandacecausative: yeah, sounds like firefox or one of the sites you visit08:14
auronandacecausative: any of those sites using flash?08:15
causativeI don't think so, I believe twitch and youtube are on html508:16
xenoix_Does it happen with all sites you've tried so far?08:17
auronandacecausative: haven't got any funky addons?08:17
causativenoscript and ublock origin, it could be a noscript problem since noscript was broken after they updated to the new firefox framework and may still be partly broken08:18
xenoix_auronandace: I mean noscript can be pretty funky, i remember last time i updated it. It broke every site i tried to visit...08:18
xenoix_causative: yeah exactly08:18
causativebut I don't think 100% of the problem is how much memory is used, the problem is the 15 minute hang instead of swapping smoothly08:19
Ben64the problem is you really need more than 4GB of memory now if you want to use web browsers08:21
causativethat's nuts08:22
Ben64700MB used on 17.10 i just installed and booted08:22
Ben64not really, 4GB was low like 10 years ago08:22
causative10 years ago my desktop computer had 512 MiB08:23
hateballcausative: Are you sure this freeze hangs when your system needs to swap? Such hangs sound like the type you can get with buggy gpu drivers also, but you'd likely see something in dmesg or ~/.xsession-errors then08:23
hateball"freeze hangs" - more coffee needed08:24
causativehateball, it always happens as soon as the green application memory bar in my status indicator reaches full08:24
Ben64maybe not quite 10 years ago, but 4GB is pathetic for now08:24
causativethis was a high end laptop 4 years ago08:25
causativecost around $800 at the time08:26
causativebut you're focusing on the wrong thing, it isn't the fact it runs out, it's what happens when it does, instead of quickly swapping08:27
Ben64the whole problem is you running out of memory08:28
causativewhy should it take 15 minutes to swap out enough memory so the system is usable?  and why would this create thousands of lines of page allocation faults in dmesg?08:29
Ben64because you ran out of memory08:29

LeFenneccan anyone help me i can't do a apt-get update10:38
Ben64LeFennec: 15.10 is long dead10:38
LeFennecwho i can fix this10:38
causativealocer, are you saying it is normal for a system to hang for 15 minutes whenever it needs to swap, and produce tons of errors?10:38
causativethis has never happened before when other ubuntu systems I have used have swapped10:39
LeFennecBen64, what i can do ?10:39
LeFennecBen64, migration ?10:39
Ben64!eolupgrade | LeFennec10:39
ubottuLeFennec: End-Of-Life is the time when security updates and support for an Ubuntu release stop, see https://wiki.ubuntu.com/Releases for more information. Looking to upgrade from an EOL release? See https://help.ubuntu.com/community/EOLUpgrades10:39
Ben64you can go from 15.10 to 16.04 and that's supported until 202110:39
alocercausative: when you have no ram available system priorites making more available.10:39
causativebut why would that take 15 minutes10:40
causativeand why would it produce 4000+ lines of dmesg errors10:40
LeFennecBen64, i can do this with live usb wwithout lose my data ?10:40
Ben64liveusb? you can do it from your installed system10:41
causativeit's a total hang, nothing responds, the screen is frozen for the 15 minutes10:41
LeFennecBen64, with upgrade (live usb == boot usb )?10:41
alocercausative: bpaste your  dmesg10:41
Ben64LeFennec: not sure what you mean10:42
causativealocer, ok I have one saved from an earlier crash10:42
causativeer, hang not crash10:42
LeFennecBen64, when i try to do an upgrade i have also errors i ask you if i can reinstall the version 16.04 without lost my files ?10:43
Ben64if you have a separate /home partition, yes10:44
causativealocer, https://pastebin.com/iSDdgysa10:44
causativenote that it does not show what happened when the crash first started because dmesg has limited size10:44
causativeI don't know how to see the earlier dmesgs from crashes like this10:44
LeFennecBen64, https://gist.github.com/anonymous/bdbb45e1470e31524f55fee1e68afca3 when i try to upgrade10:45
LeFennecBen64, no my home is in the same partition :/10:45
alocercausative: i can't open pastebin. would be kind to paste it on paste.ubuntu.com ?10:46
alocercausative: my job is to watch for linux health at my company10:48
alocercausative: one of the thing i look out for is swap. and when its get used. we bring down the system and switch the server to investigate the issue.10:49
alocercausative: if your swap gets used like that it means BAD things are happening10:49
alocerle me look into dmesg more .10:49
causativeit was using swap in 17.04 a bit but not causing problems like this10:50
causativeI would get like a 2 second hang sometimes10:50
causativeand I'm not sure that was because of the swap or something else10:50
alocerswap is not a problem here m810:51
jonnnnnnnnncan someone explain what swap memory is for and if i need it on my ubuntu installs (always is made when i install)10:52
jonnnnnnnnni have 16GB of ram10:52
alocerjonnnnnnnnn: lmgtfy.com/?q=swap10:52
alocerdoese ubuttu search on google /10:52
causativejonnnnnnnnn, it's space on your hard disk that can be used like RAM is, it's much slower than RAM but should prevent a total failure if you run out of RAM10:53
jonnnnnnnnnnah i broke the internet lols10:53
jonnnnnnnnnthanks causative10:53
alocerwrong. doesn't protect you from filure10:54
alocerprotect you from loss of dtat10:54
Ben64can't be used like ram either10:54
jonnnnnnnnnfukn hell this is personal between u2 lols10:54
jonnnnnnnnnthanks for replies10:54
Ben64watch the language please jonnnnnnnnn10:54
alocercondolenses Ben6410:55
causativealocer, what makes you say swap is not a problem?  what is the problem then?10:55
alocerdid you install the os your self ?10:56
aloceri m not a pro .. but seems like a hardware problem.. i can't figure it our man. sry10:57
causativethere might be something wrong with my SSD10:57
alocerit might be that10:57
alocerbut youre swap is working fine10:57
nesciussmart would show that10:57
causativehow do you know?10:57
nesciusswap is only used when ram is full, or when suspend/hybernate10:58
alocerits 4 years i m using linux and my swap never goest over 0 :)10:58
causativenescius, I get all these error messages and a 15 minute hang whenever my ram becomes full10:58
causativethen it comes out of the hang, and some swap is used and the system is ok for a while until it runs out again10:58
roryswap doesn't work like that, ie ram "overflow" - actually depending on swapiness, the system will keep stuff in both RAM and swap so it can be quickly removed from RAM if needed10:58
causativeI've had swappiness set to 100 for a few hours now rory and it's not using any swap at all10:59
causativeis that normal?10:59
alocercausative dmesg log > https://paste.ubuntu.com/26488497/11:00
alocercausative: you have a hardware problem.11:01
alocercausative: lots of stalled for thousand of seconds11:02
causativewith what hardware?11:02
alocerand they all happens when your trying to access you hard disk . but i don't know which one11:02
alocerudisks get stalled11:03
causativeso you think it's the SSD11:03
alocerkthread get stalled11:03
aloceryou only have ssd ?11:03
alocerpossible ... contact the system76 support.11:03
alocerand make sure you're ssd is working the way it should11:04
nesciusit could be the ssd - logs are full of this udisksd: page allocation stalls for 10444ms11:04
nesciusdo you have a smart daemon installed?11:05
causativedon't think so, getting smartmontools now11:07
causativewell, I ran a s.m.a.r.t. extended offline self-test on the ssd and it said "completed without error"11:20
causativeso it might not be the ssd11:20
causativeit's a relatively new ssd, got it last summer11:21
zomaarWhat was the issue causative?11:22
zomaarI was using a KVM switch chained to a VGA switch that apparently caused my VGA card to die but this was only temporary, but I'll have to wait till TJ- comes online again11:23
causativezomaar, whenever the system runs out of memory (but has plenty of swap) it hangs for 15 minutes and produces errors like this:  https://paste.ubuntu.com/26488497/  and then returns to apparently normal operation, having apparently used some of the swap during the hang11:23
hateballcausative: what ssd do you have? some misbehave so you need force disable ncq11:24
hateballbut then you usually notice that during normal operation as well, not just when it swaps11:24
zomaarI really would like to make a huge hardware database that people can insert their experiences into11:24
causativedevice model is SanDisk SDSSDA240G11:25
zomaarI have had huge issues with a slower, older mSATA SSD that caused kernel hangs, but not just when swapping11:25
hateballcausative: oh I see now you have a system76 machine... that should already be tested against that type of stuff I guess11:25
causativeit's not the drive that came with it hateball11:26
hateballcausative: ah!11:26
causativethat was an HDD that was failing11:26
Ben64probably doesn't help having encrypted swap11:26
hateballcausative: fwiw, you could try the kernel parameter "libata.force=noncq" and see if it's the same type of issue I've had in the past. See this post for example https://unix.stackexchange.com/questions/211550/how-to-really-disable-ncq-in-linux11:27
spexiHi! When using Spotify, it displays a notification at every song change, and it tells which artist, song and album it is. Is there a way to show that notification again after that first time?11:27
causativeyeah but... what's the point of encrypting my home directory if I'm not going to encrypt the swap11:27
zomaarProbably is no issue11:27
Ben64causative: those are totally different things11:27
causativeif i consider the information in my home directory worth encrypting, then the information in swap would be equally worth encrypting11:28
mjaykcausative: depends on the circumstance. People are different and have different applications.11:28
zomaarNo I don't think the general use case would advise against encrypted swap in that case11:28
zomaarBut YMMV11:29
Ben64it only has 4GB ram, probably a weak cpu as well, it runs out of memory and has to swap to slow encrypted swap11:29
zomaarStill it is easy to test without if th swap is separate11:29
Ben64of course it's gonna take a long time11:29
causativeben, it did not take a long time or produce errors prior to updating to 17.1011:30
zomaarIt's not the encryption11:30
Ben64it sure doesn't help the situation11:31
zomaarHave you tried older kernels?11:31
causativeno, guess I'll try that later11:31
zomaarI think it's someone the kernels folks would be interested in, but I don't really know how to get their attention11:32
zomaarDoes the mainstream kernel even have a bug tracker?11:33
zomaarIs your swap part of an encrypted LVM or separate?11:34
zomaarYou can easily create a different swap to test11:34
zomaarThe crypt device mapper target is really just one of the simplest out there...11:36
bbkingI'm trying to boot an ubuntu 16.04.03 usb on an old system11:36
bbkingthe bios appears to have no EFI11:36
zomaarTime to celebrate11:36
bbkingI wonder if the new ubuntu iso images require efi?11:37
zomaar2 rounds on the house11:37
EriC^^bbking: no, they don't they boot on both legacy and uefi systems11:37
bbkingI'm using the grub from the previous install ubuntu 1411:37
bbkingto check if it sees any boot partitions11:38
zomaarEriC^^: Is it a dual kernel image? I noticed the exention was .efi11:38
bbkingit doesnt seem to see the usb drive11:38
bbkingor it sees the drive but doesnt see it as bootable11:38
EriC^^bbking: does 'ls' show it?11:39
zomaarSo you can't boot it from the BIOS?11:39
bbkingls shows the some other stuff on the computer,  same stuff with or without usb plugged in11:39
bbkingnope, having a bloody hard time with this11:39
bbkingI have an older bootable usb too from debian -- same problem11:40
zomaarIs this the same debian person?11:40
bbkingits debian 7 I think11:40
bbkingthe old one11:40
zomaarI mean were you here before trying to get Ubuntu on a Debian machine?11:41
bbkingso I dont think its the usb itself11:41
EriC^^bbking: can you put the iso on another hdd native on the machine?11:41
bbkingshouldnt be an issue what is already on the machine11:41
zomaarEric is implying that you can boot an ISO from grub11:42
bbkingEriC^^, yeah I'm thinking, put the iso on a hdd and loop mount?11:42
bbkingright, that way I'll at least see the iso11:42
bbkingyeah that must be the next step maybe something screwy about the usb controller on the mb.11:42
bbkingusb keybaord works11:43
zomaarThere is a howto for it but it requires essentially only like 2 commands in Grub11:43
BluesKajHowdy folks11:43
bbkingone thing occurs to met11:44
bbkingto me now11:44
bbkingthere are lik 30 HDDs on that system11:44
zomaarOne to mount the loopback and one to get the root from it11:44
bbkingnot a typical desktop setup11:44
bbkingand raid controllers etc.11:44
bbkingmaybe its somehow too much for the grub shell to list them all11:45
bbkingthey dont pop up -- all of the ext4 file systems.11:45
zomaarIf your BIOS has issues with it11:45
zomaarThen you know11:45
zomaarIt's expected that Grub has too11:45
causativezomaar, hateball alocer nescius thanks for your help I have a few things to investigate now11:46
zomaarJust loopback mount the ISO and get going :)11:46
zomaarOr I mean, get it going :)11:47
EriC^^bbking: maybe cause the bios can't boot from the usb grub can't see it?11:47
EriC^^bbking: if you had the space maybe you could make a tiny fat32 in one of the disks and put the iso there so it stands out more in the ls output11:48
bbkingjeeez, I unplugged 30 HDDs and now grub shows my usb11:52
bbkingbios screwup I guess11:52

chrismlif i a command in screen and don't detach it but my ssh session times out, that will fail the command right?13:18

rreck_oh sorry i didnt understand it meant running under screen13:20
rreck_i guess i should have clued in on the word detach13:20

A1Reconnot since the error showed up13:51
zomaarOkay so a hardware error occurred maybe and your filesystem was remounted read-only13:52
zomaarIs a guess13:52
zomaarYou can check "dmesg" if there are any signs of hardware failure and also13:52

dingirSven_vB: XOR is an enxryption program?14:29
ducassedingir: by default ubuntu uses ecryptfs, not encfs14:29
Sven_vBdingir, no, an algorithm. the disadvantage is that you ned a key file at least as big as the partition you want to encrypt.14:30
dingirwhat does it mean a key file14:30
=== nescius_ is now known as nescius
dingirif i did not encrypt /home on install is it too late14:33
Sven_vBdingir, if you want to understand serious answers to your initial question, you should first read a bit about encryption in general. most probably the choice of software isn't even the biggest factor in your security scenario.14:33
ducassedingir: the ecryptfs-utils package has scripts to encrypt an existing homedir14:34
zomaardingir: Sven_vB is messing with you a little bit, XOR is not a serious encryption program14:36
dingirwhat do you think are big factors in encryption scenarios..14:37
dingiralso i have a good question14:37
Sven_vBzomaar, it's the only proven secure algo, when used as one-time pad.14:37
=== nicolo is now known as Guest5582
dingiris an encrypted partition more prominent to failures or compications from an enexpected power failure14:38
Sven_vBmost modern encryptions actually do use XOR at their base, just with a less secure algo for key bits.14:38
zomaardingir: Encrypted home directories are difficult to access from outside systems14:38
dingiram i more likely to loose everything.. like bad blocks at the bad place and you are locked out or something like that14:38
BluesKajyea you might lose it if it's loose14:39
mnkybrdrdingir: especially as I forget passwords14:39
Sven_vBdingir, yes encryption will make it harder to access your data via irregular methods.14:40
dingirsometimes i see checkdisk or something checking my file system on boot.. if its encrypted, do i have higher risks of the checkdisc being a fail14:40
zomaarI wrote my own password cracker for all the times I've lost an encryption password14:40
Sven_vBdingir, checkdisc should be unable to check your fs at all unless you provide the key.14:42
dingiris it possible it could get screwed in the right  place that even with the key it could not be read anymore14:42
zomaardingir: The problems are a) Forgetting your password b) Accessing through recovery14:42
dingirrecovery means like unexpected shutdown?14:43
Sven_vBdingir, if you use an encryption method with very small key material, like some random key stored at the start and end of your partition, encrypted with your password, and both key material sections are damaged, your entire data is gone.14:43
zomaarI would generally recommend against using eCryptFS and use encrypted /home instead, but that's just me14:44
dingirwhat you mean use encrypted /home instead14:44
dingiruse what instead of ecrypts?14:44
dingirSven_vB:  ok14:45
Sven_vBif you use XOR-OTP, only those parts of data are lost where the data disk and the key are damaged in the same spot.14:45
zomaardingir: That would be an encrypted partition that is mounted on /home and that you need to unlock at boot14:46
dingirwhere to get info.on that key thing14:46
zomaardingir: But this is not a default option in Ubuntu and would need a lot of knowledge on your part now14:46
dingirzomaar thats what id like..14:46
zomaardingir: What you can do is encrypt your entire system when you install Ubuntu14:47
zomaardingir: But Sven_vB is saying that if you use regular encryption with Ubuntu, and the start of your partition gets damaged, the entire partition is now unreadable and unrecoverable for you14:47
dingirlike once i had a hard drive failure i was able to save some files and make a partition that was containing the bad blocks and not use it anymore.. could i have save myself like that if the partition was encrypted14:48
Sven_vBzomaar, what, they only store the key material in one spot?14:48
dingirok so why is the original encryption like that..14:48
zomaardingir: You can make a backup of the encryption headers in LUKS14:49
zomaarSven_vB: I think so14:49
zomaarSven_vB: I don't think the LUKS header specification has a backup header location...14:50
dingiri have to backup the part containing the key14:50
=== LevierMRQ1 is now known as LevierMRQ
dingircause if it fails the partition is gone14:50
zomaarYes, basically that's it14:51
zomaarThen you are safe14:51
dingirand this part is called LUKS headers and this is part of how ecrypts work?14:51
Sven_vBdingir, you could sync important files to some cloud storage ;)14:51
zomaarNo it is part of how LUKS works14:51
zomaarNot eCryptFS14:51
zomaarLUKS == full system encryption14:52
zomaareCryptFS == only your individual files14:52
dingirso i should use LUKS instead of ecrypts, but luks is not original encryption option?14:52
dingiri encrypt the whole disc14:52
zomaarLUKS is the option you have when selecting "Encrypted LVM using entire disk" when you install Ubuntu14:52
sweinwhy is 16.04 desktop so picky about lightdm and ubuntu unity starting on login.14:52
zomaareCryptFS is the feature called "Encrypted Home Directories"14:53

dingirwhat does LVM stand for?14:53
ubottuTips and tricks for RAID and LVM can be found on https://help.ubuntu.com/community/Installation/SoftwareRAID and http://www.tldp.org/HOWTO/LVM-HOWTO - For software RAID, see https://help.ubuntu.com/community/FakeRaidHowto14:53
Sven_vBprobably Logical Volume Management14:54
zomaarIt's a partition table inside an encrypted partition, in this case14:54
dingirand to use LUKS i have to encrypt the whole disc, not just a partition is that correct?14:55
zomaarYes you are correct, this is true for the standard Ubuntu install14:55
zomaarAlthough you can manually encrypt only /home if you make it a different partition, but this requires a lot of manual work14:56
dingirand what is the flaw with using ecryptfs already..14:56
dingirno problem creating a partition i can do it14:56
zomaarIt is very hard to access your data from outside the system14:56
dingirlike from.ssh?14:57
zomaarIt is possible but just hard14:57
zomaarNo, when you boot the Ubuntu Live DVD and then try to access the files on your harddisk14:57
zomaarYou will find it very hard to access them using the provided scripts14:57
zomaarSo if you are in a pinch it is a liability14:58
dingiroh ok.. is it more likely for a ecryptfs partition to become unrecoverable than a luks one?14:58
zomaarIt doesn't have to be that way, it just is14:58
zomaarLet me show you the commands that are about needed to unlock it14:59
dingirecryptfs dont have headers i can make backup of?14:59
zomaarNot even sure if this works on Ubuntu15:00
zomaar  mount.ecryptfs /source /home/user -o key=passphrase:passphrase_passwd=$1,ecryptfs_cipher=aes,ecryptfs_key_bytes=32,ecryptfs_passthrough=n,no_sig_cache,ecryptfs_enable_filename_crypto=y15:00
zomaardingir: It is somewhere in your home directory15:01
zomaardingir: But hidden15:02
dingirlets say:15:02
zomaardingir: It's in /home/.ecryptfs/ or something15:02
dingiri am likely to drop the laptop off the table, is it a better idea to not encrypt filesystem in case of the hardrive being damaged.15:03
zomaardingir: For Ubuntu it would even be harder I think because it uses a wrapped password15:03
dingirlike do i have better chance to recover files from a damaged hard drive that is not encrypted or it doesnt matter15:04
zomaardingir: LUKS is pretty safe as long as you know how, eCryptFS is also safe if you have enough time and internet access to find out how to do it15:05
zomaardingir: But for LUKS you need a backup of the header just in case15:05
zomaardingir: In general your chances are reduced with encryption15:06
dingirok and for ecryptfs what kinda backup could save me15:06
zomaardag oerheks15:06
zomaardingir: A backup of your entire /home, not just /home/user15:06
zomaardingir: Or at least of your /home/.ecryptfs/ because otherwise you backup the encrypted files15:07
zomaar(I think)15:07
dingirok thanks man15:07
zomaarI just would stay away from it myself15:07
dingirdo you use encryption15:08
=== SimonNL_Afk is now known as SimonNL
zomaarI lost the key that answers that question15:09
dingirif someone encrypts his hard drice with either luks or ecryptfs and not make backups of headers and .ecryptfs folder, he is doing bad practice and looking for problems... assumption correct?15:10
zomaarDepends on other backup strategies of existing data you might have in place15:11
zomaarThere is a higher chance your LUKS header will get lost than your eCryptFS thing, but eCryptFS is just harder to use15:12
dingirok thanks again ill read on LUKS and eCryptFS15:13

Ubuntu_secHi 2 all15:51
Ubuntu_secWill future Intel/AMD microcode updates for Spectre Variant 2 require to update the Ubuntu again, or is it just firmware updates for the CPU/Chipset?15:52
jimb_s10gopal, SSD uses less power and is lighter (generally speaking)... plus the faster access times are nice. If you do a lot of filling/empty/fill/empty of the drive, then it's less suggested as SSDs do not have the same high number of rewrites as megnetic media (edge case)15:52
kostkons10gopal, go for it, did the same, replaced my 250GB HDD with an 120GB SSD15:54
oerheksUbuntu_sec, the full pach would be the new microcode, when it is ready, and kernel 4.15. but that kernel won't be backported to 17.10, i hope it will be available in 18.04 LTS15:54

oerheksUbuntu_sec, it would be wise to update to 18.04. when released, older versions will not get the full patched 4.15 kernel AFAIK15:59
oerhekss10gopal, it is a HP issue, not only your model laptop, why do you still spam this bugreport?15:59
Ubuntu_secoerheks - it's beyond my control, this is an AWS image provided by another company15:59
s10gopalall laptop has this issue and it is os problem not hardware problem16:00
oerheksUbuntu_sec, ask them for an updated image?16:00
Ubuntu_secoerheks - isn't LTS 14.04 still supported?16:00
oerheksUbuntu_sec, yes, they are, but this issue is so deep in hardware, i think it breaks this cycle16:01
Ubuntu_secoerheks - they say they would need to test it thoroughly, and it can take weeks/months. We need to be protected16:01
Ubuntu_secoerheks - so update to 18.04 will be the only option to be fully protected?16:02
oerheksUbuntu_sec,  then ask your intel/amd vendor to provide a good safe cpu16:02
Ubuntu_secoerheks - such CPUs don't exist yet. What will be our options to be protected - only upgrade to 18.04 LTS ?16:03
ubottuSpectre is a security issue in almost all modern processors, which was released along with !Meltdown (but is not the same thing). While there are several initiatives underway to mitigate it, there is no "magic bullet" software fix. Ubuntu is monitoring ongoing efforts and will provide security updates as they become available. See !usn for security update notifications.16:03
ubottuPlease see http://www.ubuntu.com/usn for information about recent Ubuntu security updates.16:04

Sven_vBfor anyone with similar problems: I was able to get rid of the non-repainting screen area by de- and re-activating compositing in Settings > Window manager tweaks.16:07
Ubuntu_secoerheks - I need to come back to my management with a clear answer  - will 14.04 LTS support the new microcode? If yes - will this require to run another update of the OS itself? If 14.04 LTS may not support the new microcode - what are our options to mitigate - is it only upgrade to 18.04 LTS?16:08
oerheksUbuntu_sec, new microcode is in working progress, you would get it with regular updates when available16:09
oerheksyou can read here that the last update is pulled back, advisory by intel16:10
oerheksand it will be published in usn16:10
oerheksAnd yes, the safest way is to update to 18.04, ask your AWS vendor for the image, it will be released end of april 201816:11
Ubuntu_secoerheks - so 14.04 LTS is likely to get this support through running "sudo apt-get update" and "sudo apt-get dist-upgrade"? No upgrade to 18.04 LTS will be required? Hopefully the microcode will be released before April, so we would like to be protected as soon as it's available16:12
oerheksas 4.15 is just released, see kernel.org, intel can do their best to make it safe again. nothing we can do now16:13
Ubuntu_secoerheks - so the 3.xx kernel will not get patched?16:17
oerheksUbuntu_sec, no, see16:18
ubottuMeltdown is a security issue with (primarily) Intel processors. It's mitigated by kernel patches named KPTI. Ubuntu released them in security updates for 14.04, 16.04, and 17.10. 17.04 will not receive this update. 18.04 will ship with kernel 4.15, which is patched already. 16.04 has updates for Linux 4.4 (release) and 4.13 (HWE), installs with 4.10 should upgrade to 4.13. See also !spectre, !nopti16:18
Ubuntu_secoerheks - can I use kernel 4.15 in 14.04 LTS?16:19
oerhekswith HWE you would get a newer kernel16:19
oerheksnot sure 14.04 LTS will get that kernel ..16:19
ubottuThe Ubuntu LTS enablement stacks provide newer kernel and X support for existing LTS releases, see https://wiki.ubuntu.com/Kernel/LTSEnablementStack16:20
Ubuntu_secoerheks - so if Intel releases the microcode before 18.04 LTS is released - how do we get that fully patched kernel? Will 16.04 LTS be any better?16:21
oerheksmicrocode is not the fully patched kernel, these are 2 seperate things16:23
oerheksi guess 16.04 is better than the 'old 14.0416:23
Ubuntu_secoerheks - thank you! Is there a blog post/article detailing all these option for full protection of Spectre Variant 2?16:28
naccoerheks: 14.04 won't, they are on 4.4 (HWE) and that is getting the same patch 16.04.1 is16:29

AmisHello! What is the most simple way to forward a port from server A to a local port on computer B? I do not have access to server A (it's a webserver) but I do have full access to computer B. Computer B is an ubuntu machine.17:56
naccAmis: afaik, you'd either need access to the router in front of A or to A itself.17:56
Amisnacc, no simple "forwarding" like.... emulating NAT or something on an Ubuntu machine?17:57
naccAmis: I don't understand how you'd forward traffic intended for A if you don't modify A or the network in front of A.17:58
maximCHif you can't access computer A or all routers that directly connect to computer A it can't be done.17:58
TJ-Amis: if you want a port on A forwarded elsewhere you need admin access to A17:58

naccAmis: your request doesn't make sense as currently expressed17:58
naccneurre: yes17:58
neurrei installed win 10, then ubuntu, then after a while ubuntu stopped from booting, there is no grub menu visible at all17:59
Amisnacc, maximCH : sorry. My questing was misleading. I CAN access the port on server A that I want to forward. I just don't have real access like SSH or anything like that.17:59

Gencadeneurre: Hm.  Is ubuntu listed at all in your boot menu?18:00
Amisnacc, maximCH : it's pretty simple, I may be just bad at explaining :D. Say computer B can access imgur.com:80. There's computer C without internet access but can see computer B so I want to imgur:80 -> B:8080 -> C18:01
neurreGencade, I dont get a boot menu. Or do you mean bios/uefi? Only windows in bios/uefi18:01
neurreUnless I go to uefi bios, no menu ever shows up18:01
AmisSo computer B is like a router...18:01
neurrei have fast boot and secure boot disabled18:02
maximCHAmis:  so you want to use computer B e.g. as a proxy ...18:02
AmismaximCH, sorta18:02
AmisBut for just one single IP:PORT combo, nothing complicated18:02
neurreanyway I am happy to nuke this ubuntu installation and reinstall it18:02
neurrebut the installer will not offer install alongside option18:03
maximCHAmis: ssh into computer B with -D 8080 set ... then set the proxy of the web browser on the computer you're using to access computer B to localhost:8080 ... and then you can access computer A from the machine you're logging into computer B from.18:03

neurreinstaller is stuck on Detecting filesystems...18:23
neurrewhat can I do?18:23
TJ-arooni: well that log is full of UFW blocking messages but not boot or suspend/resume history. Looks like you need to fix those UFW rules since it looks to be blocking a lot of local and IPv6 connections18:23

FrameFevernacc: I can install it, but It seems to be not 32 bit18:24
neurreanyone know about the Ubuntu installer?18:25
neurreit seems to be stuck for me :(18:25
naccFrameFever: using what package name?18:26
sepiakid66some sort of gnome error18:26
sravanneurre: mention the difficulties18:26
neurreThe installer UI is stuck, it shows Detecting file systems...18:27
neurreThere is Skip button, but it is ghosted18:27
neurreit is not making any progress18:27
neurreand I am afraid this computer might not boot properly now18:28
sepiakid67try reinstalling18:28
neurreis there anything I could do at this point?18:28
neurrecan i just kill the installer?18:28
oerheksneure, looking at that output, sda2 is ntfs, but not found.. maybe it contains errors?18:28
sepiakid66well if nothing happens, then get another copy18:28
oerheksneure, did you resize it ?18:28
TJ-arooni: you'll need to capture a log just after it fails when the kernel messages are still there, rather than being swamped with UFW messages18:29
sravanare you using USB or Disc?18:29
sepiakid66try wiping it with gparted18:29
neurrei chose the install along side in the begining, the installer prompted to choose how the partitions are sized, I did not make any changes18:29
neurrethere is pre-existing non-working installation18:29
neurreso I kill the installer now?18:29
oerheksneurre, "there is pre-existing non-working installation"... any more info you forget to mention?18:30
neurreoerheks, I had machine with Windows 10. I installed ubuntu to it (alongside). I was able to dual boot for a while, then grub/ubuntu boot option disappeared18:31
lotuspsychjesravan: can this help? https://www.linux.com/learn/how-sync-android-linux-desktop18:31
neurreand the computer keeps booting directly to windows. I suspect some windows update overwrote MBR or something18:31
neurreso i am trying to get linux back to this computer18:32
neurreso i run installed again from live USB stick18:32
oerheksneurre, that can easily be fixed, boot the live iso and follow the reinstall grub from the !grub wiki18:32
ubottuGRUB2 is the default Ubuntu boot manager. Lost GRUB after installing Windows? See https://help.ubuntu.com/community/RestoreGrub - For more information and troubleshooting for GRUB2 please refer to https://help.ubuntu.com/community/Grub218:32
sravanneurre: nothing wrong in rebooting the system18:32
neurreoerheks, well the linux installation does not seem to be a functional one, it is missing /bin for example...18:32
neurrei have no idea why18:32
neurreI tried one of the fix steps (chroot) from the link you posted18:33
neurreI'll just kill the installer and try again18:33
neurrei could try to remove the old linux installation completely18:34
sravanneurre: i think that make sense.18:34
neurrewhat is the installer called?18:34
sravantry from scratch again18:34
neurrei dont immediately spot it with ps18:34
zomaarbut you need to close down everything before you retry again18:35
zomaarIe. you have to deactivate swap18:35
zomaarAnd close filesystems18:35
neurreso easier just reboot?18:35
zomaarOr it will fail with horrible spasms18:35
neurreyou think if i reboot at this point I can still to windows ?18:35
zomaarIf that doesn't take time for you18:35
zomaarGrub should have been installed with Windows as option, if it was installed at all18:36
zomaarThe bootloader doesn't always work though....18:36
neurreim not sure what you mean18:36
zomaarSmart thinking though18:36
zomaarWas Grub installed?18:36
sravanneurre: If u didn't touch d drive in which u installed windows, nothing to worry. U can try from the scratch18:36
neurrehas it already been installed at this point?18:36

neurresravan, in the beginning it says it does save some changes on the drive18:36
neurrebut it is not very explicit about what changes it does18:37
neurresome partition table stuff i think18:37
neurrevery scary18:37
neurreoh well18:37
neurrei will try my luck18:37
zomaarHow soon did you break off?18:37
sravangutji: Please go to the setting and change the device config.18:37
neurreit is stuck in the step where it has asked about time zone18:37
neurreand keyboard18:37
neurrebut not asked about user name yet18:38
zomaarThen I don't think it has installed Grub18:38
neurrebut it did save *some* changes18:38
gutjisravan: where exactly18:38
neurrei hope those did not erase windows boot loader..18:38
zomaarYes partition table18:38
neurrethen I will just reboot the USB18:38
zomaarIf you complete you can boot through Grub anyway18:39
zomaarIt wasn't necessary to reinstall Linux though18:39

FuraiHey, did any of you guys use SonicWall's NetExtender in the latest version of ubuntu? I can't seem to make it work. There must be some routing issue or something.18:48

neurrecp is fast but sync after takes ages :P18:49
lotuspsychje!who | zomaar neurre18:50
ubottuzomaar neurre: As you can see, this is a large channel. If you're speaking to someone in particular, please put their nickname in what you say (use !tab), or else messages get lost and it becomes confusing :)18:50
Furainacc, as far as I know it's not.18:50
naccFurai: then you want to contact SonicWall, not us :)18:51
zomaarNot applicable, ubottu ;-)18:51
FuraiI'm asking here if someone had some experience with it, that's all. Maybe someone already did make it work somehow. Anyway, thanks.18:51
naccFurai: polling is also not really appropriate for this channel, and any related discussion would end up offtopic18:52
neurrecan i see progress of sync somehow?18:52
naccneurre: of the `sync` command?18:52
sravangutji: please confirm that hardware is properly connected and not muted18:52
neurrenacc, yes18:52
naccneurre: not really18:52
neurreso I cannot see filesystem cache used buffer size anyhow?18:53
sravanlotuspsychje: Thank you! it worked. (https://www.linux.com/learn/how-sync-android-linux-desktop)18:53

ubottusravan: Glad you made it! :-)18:54
FrameFevernacc: g++-4.918:54
naccneurre: sure, but seeing what is in the fs cache won't change that. sync doesn't drop the chache18:54
FrameFeverI want to install g++-4.9-multilib18:54
naccFrameFever: taht package is not available on 14.04. `apt-cache policy g++-4.9` in a pastebin please.18:54
naccFrameFever: not available *from ubuntu*, that is18:55
neurrehow about filesystem statistics?18:55
lotuspsychje!latest | FrameFever18:55
ubottuFrameFever: Packages in Ubuntu may not be the latest. Ubuntu aims for stability, so "latest" may not be a good idea. Post-release updates are only considered if they are fixes for security vulnerabilities, high impact bug fixes, or unintrusive bug fixes with substantial benefit. See also !backports, !sru, and !ppa.18:55
neurreis there something that can show how much data is being read/written for each filesystem?18:55
zomaarneurre: what sync command are you talking about?18:55
FrameFevernacc: I need this package on travis18:55
FrameFeverthere is only 14.0418:55
neurrezomaar, I did cp stuff from linux filesystem to USB drive18:55
FrameFeverright now I am testing live on 16.0418:55
sravanthank you <lotuspsychje> <ubottu>18:56
neurrezomaar, then I did "sync" to make sure the stuff actually goes to the stick18:56
zomaarneurre: Oh18:56
neurreit is USB3 stick so it should not be too slow18:56
lotuspsychjesravan: celementine can sync music to phones too, have you tested?18:56

qswzmsg nickserv identify hunter218:59
GalaxorTwo machines I'm on are using slightly different collations.  It's making it hard to compare directory contents, because ls returns the filenames in different orders, and the sort command sorts it in the same way as ls, so the sort output is different on the different machines too.19:01
zomaarGalaxor: You can use LANG=C if you want19:02
GalaxorI'm thinking this has something to do with locales, but I don't know what the deal is.  echo $LANG yields en_US.UTF-8 on both.19:02
neurrefunny, seems like I cannot even sudo kill -9 the sync process :P19:02
Galaxorzomaar: Oh, good idea, thanks.19:03
akikGalaxor: try LC_COLLATE=C19:03
naccneurre: right, it'll be in uninterruptible sleep19:03
naccneurre: 'D' state19:03
naccneurre: killing it would be a bad idea generally19:03
cruzadorHey guys, hoping for an explanation here. I have my boss who is starting a screen session on a VPS under 'user'. When I login as root, su - user, then try to attach I get "Cannot open your terminal '/dev/pts/1' - please check.". But, if I do this "script /dev/null" before running "screen -x", it works! Why is that?19:03
neurrei think im just going to reboot and try again next time19:03
TJ-neurre: if sync is TASK_UNINTERRUPTABLE only a reboot will work19:03
zomaarUnplug the stick19:03
zomaarTry a smaller write19:04
Galaxorakik: Aha, I tried to set LC_COLLATE=C, and I think I found the source of the difference.  One of the machines responded "-bash: warning: setlocale: LC_COLLATE: cannot change locale (en_US.UTF-8): No such file or directory".19:04
akikGalaxor: LC_COLLATE=C makes it show dot files/dirs first19:04
neurrezomaar, that did it :D19:04
neurreidk why that stick didnt make any progress19:04
Galaxorakik: So it looks like I haven't actually installed en_US.UTF-8 on that machine.19:04
neurrei'll try another one19:04
zomaarneurre: You can also do sudo sysctl vm.dirty_writeback_bytes=1048768 to have almost zero write buffers19:05
zomaarAnd dirty_bytes to 2* that19:06
cruzadornvm, found my answer here: https://serverfault.com/questions/255521/why-does-redirecting-script-to-dev-null-allow-screen-to-work-while-sued-a :)19:06
zomaarneurre: If you do sudo sysctl vm.dirty_bytes=1048768 you will have 1MB of max write buffers for the entire system19:07
zomaarneurre: Then if you do cp -v you will see the actual progress19:07
neurrethat is exactly what im doing now19:08
gutjisravan: It is conencted indeed, now the sound cracks19:08
neurreI see what i was copying now19:08
neurreeven cp goes to D state19:08
GalaxorSo, I installed the locale and now the two sort the same way.  I ran:  sudo /usr/share/locales/install-language-pack en_US.UTF-819:09
oerheksfresh ClamAV available https://usn.ubuntu.com/usn/usn-3550-1/19:11

zomaarIf you didn't botch the existing install you don't need to19:14
zomaarBut the installer deletes everything @neurre19:14
neurrei am afraid my installation is already broken19:14
neurrebut I think my Live USB stick is not good19:14
neurrei got a different issue now19:14

wodimwhat does this mean19:37
kostkonwodim, apt-cache policy libmagickwand-de libmagickwand-6.q16-dev19:38
kostkonwodim, sorry, that should be   apt-cache policy libmagickwand-dev libmagickwand-6.q16-dev19:39
wodimkostkon, ^19:39
kostkonwodim, do a   sudo apt-get clean   then a   sudo apt-get update   and try again19:40
wodimexactly the same19:40
kostkonwodim, might be a problem with the mirror, you could try changing to a different one in software & updates (alternatively open your updater and click on settings)19:41

wodimI'm not going to install the python library from the repos if that's what you're going to suggest19:43
leftyfbwodim: which pypi package?19:43

leftyfbwhat's zesty?19:49
kostkonwodim, where?19:49
leftyfbfrom your pastebin, it looks like you're running xenial. You shouldn't have any zesty repo's enabled or else you run into issues similar to what you're experiencing19:49

ToxygeneDoes anyone know if Ubuntu / bash have a per-user version of /etc/profile.d?20:08
ToxygeneSomething like ~/.bash_profile.d/ ?20:09
jimb_Toxygene, such as ~/.bashrc ?20:11
ToxygeneMore like a per-user directory that all the files in it are source'd20:12
maximCHAmis: you're welcome .. :) (sorry... was afk)20:12
jimb_Toxygene, well, the ~/.bashrc is sourced at login20:13
leftyfbToxygene: https://medium.com/@waxzce/use-bashrc-d-directory-instead-of-bloated-bashrc-50204d5389ff20:13
Sohron_Toxygene: one can source anything from ~/.bashrc20:14
Toxygeneleftyfb: Perfect, that looks like what I'm looking for20:15
jimb_leftyfb, Interesting... instead of a single file broken up into groups, the idea is to create many files with the same content that would have been merged into one.20:15
Sohron_Toxygene: look at /etc/bash.bashrc20:15
leftyfbjimb_: it's good for profiles based on machine or ssh key or work/home20:15
Sohron_Toxygene: look at /etc/profile20:15
Sohron_though :D20:15
akikleftyfb: man bash doesn't mention .bashrc.d ?20:16
leftyfbakik: it's not a thing. Just create it yourself and add to .bashrc to source everything in it20:16
leftyfbakik: it could be called ~/.mystuff for all anyone cares :)20:16
akikyea no thanks20:16
ToxygeneYea, that's even better. I can create /etc/profile.d/per-user-things and that'll source everything in $HOME/.profile.d20:17
jimb_leftyfb, I see how it could be useful if you wanted to use specific versions of each file for certain users. Thanks for the info.20:18
iorianot everything20:20
leftyfbioria: not everything?20:23
iorialeftyfb, for env is good, but func definitions are available only in n that shell instance20:24
iorialeftyfb, you still need .bashrc20:24
TheSHAD0WHaving some head-scratching problems with samba.  ioria: Still on?20:34
leftyfbioria: I don't follow. I have functions in .bashrc.d and sourced using .bashrc20:34
iorialeftyfb, i thought we were talking about  /etc/profile.d ..20:34
leftyfbioria: nope, I don't use that.20:35
TheSHAD0Wioria: Still having some issues.  I enabled SMBv1 on this machine to see if that was part of the problem.  When I did, the machine did pop up under the file manager...  But so did another machine that doesn't have v1 enabled.20:35
iorialeftyfb, sy, that's what Toxygene said ... /etc/profile.d20:35
ioriaTheSHAD0W, how ? Add-WindowsFeature FS-SMB1 ?20:36
TheSHAD0WThis was enabled on the Windows machine.20:39
TheSHAD0WThis was working before, so I'd guess SMBv1 was enabled back then.  At some point SMBv1 was disabled by default, due to security problems.20:40
ImageJPEGI see there's php-fpm and php7.0-fpm. What version is the former?20:42
jerichowasahoaxImageJPEG: I want to say 5.x but I'm not entirely sure20:42
jerichowasahoax!info php-fpm20:42
ubottuphp-fpm (source: php-defaults (54ubuntu1)): server-side, HTML-embedded scripting language (FPM-CGI binary) (default). In component universe, is optional. Version 1:7.1+54ubuntu1 (artful), package size 3 kB, installed size 12 kB20:42
Outysyntax question:  I try to learn find. I try to find a folder called "Scans" so I do search for "can" like this:  find .  -path '*can*'     but this will also print out files with "can" in its file names20:42
Outywhere am i wrong20:43
jerichowasahoaxImageJPEG: actually now that i think about it, php-fpm could just be a virtual package that acts like an "alias" for php7.0-fpm20:43
ioriaTheSHAD0W, try enable it again (but it's a winn issue, i guess)20:43
dv`_Outy: -type d20:43
ioriaTheSHAD0W, something like : Enable-WindowsOptionalFeature20:44
Outydv but is -path not excluding file names ?20:44
Outydv why is there -name and -path when it makes no difference  im confused20:45
dv`_Outy: -path is full path, -name is just the filename20:45
jimb_Outy, `find ./ -type d -iname Scans`20:46
Outythanks dv & jimb  will try and learn20:47
dv`_the manual page is your best friend for that20:47
jimb_Outy, `man find`20:47
* jimb_ loves `find`, especially when used with -exec20:48
=== z__ is now known as sadtaco
TheSHAD0Wioria: It's more complicated than that, it seems.  Still testing.  This may be fun.  :-P20:49
ioriaTheSHAD0W, ok, but you have a win7 config that i ever met20:50
Outywanted this to work my way:  find /media/hal9000/SanDisk\ SDXC/ -path -type d '*can*'   but now it gives me: find: paths must precede expression: d20:51

TheSHAD0WWell, seems Win7 doesn't disable SMBv1 by default, apparently I did it manually.20:51
Outyfound it20:52
TheSHAD0WThe problem is, SMB1 has a serious vulnerability and is deprecated.  Win10 has it disabled by default.20:52
Outyfirst -type d then -path20:52
TheSHAD0WI'm wondering if there's a problem with Samba in that it doesn't pick up devices that only have SMB2.  Win8+ has SMB3.20:53
ioriaTheSHAD0W, samba should be use only on lan,  behind  a router fw20:53
TheSHAD0Wioria: Yup, and that's what I'm doing, but still.20:54
Outydv & jimb : got it -name can be characters in a filename or dirname20:56
ImageJPEGYep, php-fpm seems to be a meta package20:57
Outy-type d is for searchin in dirnames only20:57
jimb_Outy, Yes. I use "-iname" as it's not case sensitive20:57
jimb_Outy, Yes. Since you were looking explicitly for a directory, I figured that would reduce wasteless output20:57
Outyjimb read that a sec ago :)20:57
jimb_Outy, When searching for find usage information, it may also be helpful to look for `GNU find` versus only `find`... ambiguous word20:59
Outyjimb thanks, i read about version differences before - im aware of that :)21:00
Outyjimb_:  im using linux for 1,5y now  time to go depper21:01
jimb_Outy, You are welcome.21:01
jimb_Outy, if you ever think you have went deep enough... then grab some of the kernel bugs and pluck away ;)21:01
Outyjimb_:  *smiles*  that will take some time ^^21:02
lolBananaI am setting up LXD for the first time and I want to get it so it would put any new containers on my local network just like a VM would, I am following the guide here: https://insights.ubuntu.com/2016/04/07/lxd-networking-lxdbr0-explained/ but I am a bit confused, since my port isn't eth0 should i replace eth0 with whatever the name of the port I have?21:03
OutylolBanana: ifconfig will show your network devices very well21:04
lolBananaOuty: i know  that but i am confused as to how i should issue the command so that LXD containers would use my local network rather its own bridge21:05
lolBananaOuty: article says the command is "lxc profile device set default eth0 parent eth0" should I replace 'eth0' with the name of my port that shows in ifconfig?21:05
nacclolBanana: well it still uses its own bridge, it's just a bridge to an actual physical device21:05
nacclolBanana: that is nont what the article says (containerbr) at the end21:06
* TheSHAD0W will leave SMBv1 enabled for now, wannacrypt probably won't make it onto his intranet but you never know21:06
TheSHAD0WThank you ioria.21:06
nacclolBanana: but yes, you want to s/eth0/your device name/21:06
TheSHAD0W... Who's gone.21:06
OutylolBanana: is ther a lot code to replace?  maybe someone knows how to redirect or link eth0 to whatever eth* device you have21:07
lolBanananacc: ok so, my port is enp0s3 so the command should be "lxc profile device set default eth0 parent enp0s3" ?21:07
Outylike a virtual device21:07
Outythats what i thougt of21:08
nacclolBanana: no.21:08
nacclolBanana: again, you seem to be misreading the page?21:08
nacclolBanana: you are oly chaning eth0 to somethign else21:08
lolBanananacc: so how should i write command?21:09
nacclolBanana: ok, read the page again. You are only changing eth0 to enp0s3. Not other strings to other stringns.21:09
nacclolBanana: you can start at the sentence 'Sometimes, though, ...'21:10
lolBanananacc: those aren't commands, i read that but those aren't commands21:10
nacclolBanana: what?21:10
nacclolBanana: which method are you trying to do?21:10
anarky999Can someone answer a question about gnu ddrescue?21:11
Outyanarky999: i can21:11
Outyanarky999: doingg this all day helping me to rescue data for my customers21:12
anarky999Ok the hard drive stopped being readable after 1tb of data was recovered21:12
anarky999cannot find input21:12
anarky999is the img file still recoverable?21:13
Outyanarky999: how big is the hdd in total21:13
Outyanarky999: and yes there are ways21:13
anarky999i used the disks utility to try restoring the img and it says it will take 24 hrs21:14
srulii am trying to copy a ecryptfs dir with cp i get an error for most files that "file name is too long", i tried with rsync -azvh and it shows at the end errors encountered without specifying and the target dir is larger than the source.. wha is the best way to copy such a dir?21:14
Outyanarky999: is it possible (with opened pc) to pull power cable and reattach it again - cause hdd will get available again under linux then you can run ddrescue command again with same options to continue the rescue. but only in case you set a logfile21:16
Outyanarky999: my command goes like this  ddrescue -d -vv /dev/sdX  /targetpath/image.dd /targetpath/image.log21:18
anarky999I tried that it only worked a couple times. Now the drive won't load even on windows. My question is about the already recovered data. Is it usable in its current form?21:18
anarky999tried the unpluging thing*21:18
Outyanarky999: yes: sudo apt-get install testdisk21:18
Outyanarky999: sudo testdisk /pathtoimage/image.dd21:19
Outyanarky999: testdisk -> no log -> Intel Partition if Windows File System on it or GPT when dealing wind Windows 8 and up21:21
anarky999you lost me hold on21:21
Outyanarky999: the you can try the file utils to copy all available files21:22
Outyanarky999: if no partition is found use analyse option before21:22
lolBanananacc: i am trying to get any LXD containers to grab ip addresses of my local network 192.168.4.x and be accessible via openssh21:22

CoffeeMonsterHi all. I have an old laptop with a broken screen, that I turned into a Ubuntu desktop (so with GUI, using an external monitor). I installed 17.04 on it, and was able to disable the laptop's internal monitor; all was well. I just upgraded to 17.10, and now all I see on my external monitor is a purple-ish screen. I am able to move the mouse further to the left, as if there was another screen:21:48
CoffeeMonsterthis makes me think the upgrade re-enabled the laptop's internal monitor. Any idea how I could disable the internal monitor again? Something like win+p in Windows.21:48
nacclolBanana: oh wait, i see now, i was wrong21:48
lolBanananacc: sorry but what's the full command21:48
lolBananaam i grabbing for the enp ether port?21:48
shazbotmcnastyaww he lef'21:48
nacclolBanana: try `lxc profile device set default eth0 parent enp0s3`; `lxc profile device set default eth0 nictype macvlan`21:48
nacclolBanana: that says to set the parent of the eth0 device in the default profile to enp0s321:49
nacclolBanana: and then to set the nictype of the eth0 device in the default profile to macvlan21:49
CoffeeMonsterI have SSH access to the laptop btw21:49
lolBanananacc: ok it did not reject those commands let me spin up a container21:50
lolBanananacc: is there any particular answers i would need to give after "lxd init"?21:51
nacclolBanana: wait, you should have allready run `lxd init`21:51
lolBanananacc: i did and i just went with the default answers but i was not sure if i had to select something different since what i am wanting to do is not done by default21:52
nacclolBanana: no, you first do `lxd init`, then do the config changes21:53
lolBanananacc: so having selected the default choices i should be fine?21:53
leftyfbCoffeeMonster: 17.04 is no longer supported21:53
leftyfbCoffeeMonster: sorry, I didn't finih reading :)21:54
nacclolBanana: sorry, you ran `lxd init` before ora fter the macvlan changes?21:54

lolBananaoh ok22:12
lolBananai wasn't aware22:12
lolBanananacc: storage pools is what i am talking about, https://insights.ubuntu.com/2017/07/12/storage-management-in-lxd-2-15/22:12
nacclolBanana: right, 'format' is the wrong concept22:13
nacclolBanana: container storage isn't formatted22:13
nacclolBanana: zfs is less about the fs-parts of it and more about how zfs can do disk management22:13
lolBananai see ok22:13

lolBanana_nacc: thanks again for the explanation and earlier help22:15

akikCoffeeMonster: try selecting the ubuntu on xorg in the login screen22:18
CoffeeMonsterakik I can't see the login screen, I think it's on the internal monitor of the laptop (which i can't see). i literally see nothing except a purple screen and my mouse22:20
nacclolBanana_: yw22:22
CoffeeMonsterIs there a way to start a graphical remote connection to Ubuntu Desktop, a bit like RDP on Windows? I found something about xRDP, but it also said it was only available on Ubuntu Server22:22
naccCoffeeMonster: nothing is "only" available on "Ubuntu Server"22:22
naccCoffeeMonster: it's all the same set of packages22:22
naccCoffeeMonster: you can use rdp, i believe, or you can use vnc, or ssh -X, etc.22:22
lolBanana_CoffeeMonster: you can use teamviewer as well22:23
hidarii use xrdp on all my systems.  works great22:23
hidariworks better than vnc for me22:24
CoffeeMonsterOh, I like the sound of Teamviewer... I'll try these suggestions, and I'll come back to cry if it doesn't work22:25
CoffeeMonsterThanks :)22:25
lolBanana_CoffeeMonster: just keep in mind you will need to install teamviewer through CLI, and force the install22:27

lakitui know22:57
lakituthat's why i gotta upgrade22:57
nacclakitu: so not sure what you're asking?22:57
lakitui'm in 17.0422:57
naccbetter than what, it's required in your case22:57
lakitubetter than times of yore22:57
lakituwhen a upgrade was a risky proposition22:57
nacclakitu: please be specific.22:57
lakituanyone else know how reliable it is to?22:58
nacclakitu: you are not doing a normal upgrade anyways, you're doing an eol upgrade22:58
nacclakitu: in general, keep your system up to date in the first place and the upgrades are painless, ime22:58
lakitui have updates in their default settings. i am now required to upgrade to the next version, & seeing if that's doable, in the modern iteration22:59
lakitu((of Ubuntu))22:59
nacclakitu: it's always been 'doable'. you are being very vague23:00
nacclakitu: perhaps you would be happier on a LTS relelase23:00
lakitusome versions were not smooth to upgrade from, to23:01
lakitumaybe google / someone else has an opinion23:01

lakituin the past there were issues23:03
lakituwith some23:03
nacclakitu: ok, this is the support channel. If you have an actual support issue, please ask.23:03
lakituobviously i don't nacc haha. only asking if it is a safe proposition to upgrade my whole system...23:04
lakitui'll google from now on23:04
oerhekslakitu, you will never know for sure, untill you do: backup your data .. wait, if you don't have a backup, your data is unimportant :-D23:04
nacclakitu: eol upgrades are (IMO) inherently more tricky. It should work fine, but you'll need to follow the instructions23:04
