osx5hi all00:35
osx5haven't been on linux in a long time, is there  a reason MS doesn't let you run ubuntu in Windows anymore? didn't it used to show up as a program in control panel?00:36
osx5i see they let you run the shell still00:36
tomreyn!wsl | osx500:36
ubottuosx5: Windows 10 has a feature called Windows Subsystem for Linux, which allows it to run Ubuntu (and other Linux distro) userspace programs without porting/recompliation. For discussion and support, see #ubuntu-on-windows or ##windows. For installation instructions, see https://msdn.microsoft.com/en-us/commandline/wsl/install_guide00:36
tomreynothert than that, for windows questions, best turn to ##windows00:36
osx5i prefer ubuntu honestly00:37
osx5but you all get the driver support monopoly MS has00:37
MarkB2matsaman: ffmpeg can get at some of the damaged files... but the rest of them stop short with an input/output error.00:38

dman777hello, I am using the ubuntu server installation for 18.*. In the storage configuration I used LVM so I could have luks. I created a vg0 and made a /boot volume and a / volume. However, the done is greyed out and I can not move forward. Anyone know what I am missing here to where the done is greyed out?01:37
tomreynmaybe an efi system partition?01:38
=== poggers is now known as jess
dman777Hmm... I have one that already exists01:41
dman777that's still probably the issue though01:43
tomreynyou may need to set it upo to be used as esp, yes01:44
dman777strange...the installer crashed and I need to do it all over again01:57
dman777looks like maybe curtin and rsync errors?02:08
dman777I am willing to bet this is specifci to lvm02:10
tomreynmaybe your .iso is just broken?02:11
tomreynor not the latest 18.04 installer02:11
dman777the iso gives me the option to update the installer.... I tried both the updated ver and non updated ver02:11
tomreynthat's correct, but not what i meant02:15
dman777I tried without the lvm options and no errors this time02:15
tomreyndid you verify the iso checksums02:15
dman777but shouldn't it work regardles if I update the installer?02:16
dman777oh...it just errored out02:17
tomreynthe base image is one thing, data if you want,t he installer is the other thing02:17
tomreynpart of it may have downloaded properly, other parts not02:17
dman777ok, let me remake the usb iso02:17
tomreynfirst of all ensure the downloaded iso file is correct, then write it to installer media, then verify it was written properly02:17
tomreynthat's how you do it if you're taking your time serious02:18
=== denningsrogue7 is now known as denningsrogue
dman777how do you verify it was written to the usb correctly?02:18
tomreynusing a software which does it automatically, such as balena etcher (if you want a bloated gui tool, which usually just works, x-platform), or using dd02:19
dman777I use dd to write the iso to the usb02:19
chietahow to generate traffic using iperf on specific interface ... i tried create some bandwith usage to specific interface let's say ens0p2 using iperf but no luck with this $ iperf -c localhost --bind ens0p2 -w 15K02:19
tomreynchieta: is that an ubuntu question njow? since initially it was a debian question?02:20
oerheksdman777, one verifies the iso before writing with dd02:20
ubottuTo verify your Ubuntu ISO image (or other files for which a checksum is provided), see https://ubuntu.com/tutorials/how-to-verify-ubuntu02:20
chietait was tomreyn02:21
dman777is it possible to verify the desktop version of ubuntu 18 and deselect software like gnome not to be installed? I tried but didn't get the options02:24
tomreyn!YY.MM | dman77702:24
ubottudman777: Ubuntu version numbers are: YY.MM (YY=release year,MM=release month). Each year sees two releases, so just specifying YY is imprecise. See also https://www.ubuntu.com/about/release-cycle02:24

matsamanwith cfdisk or fdisk or gdisk or gptfdisk or sgdisk or parted03:01

SpeirosHi all. Can anyone tell me some simple commands for browsing the logs. I am at present typing the date day by day in a browser and perusing this way. I was wondering if there was a way to keyword the whole database.07:34
SpeirosSee, I'm trying to find the first date I ever came on here under this nick, but I've only found it at June 6th, 2010 so far.07:35
SpeirosI think there's at least another two hidden years.07:35
ThinkT510if it is in text you could grep for your nick (i'm assuming the logs you are referring to are this channel's irc logs)07:38
SpeirosYes, they're this channel's logs, ThinkT510. Where would I type this, and how should it be worded? Excuse my ignorance.07:39
ThinkT510if you wanted to find if firefox was running you would: "ps aux | grep firefox" then each line with firefox would pop up in the terminal. I'm not sure how to feed a txt file to grep in the terminal though.07:45
SpeirosOkay. Thanks anyhow, ThinkT510 :)07:45
ThinkT510Speiros: I suppose if you are viewing them in a browser you could use ctrl+F and search for your nick07:47
SpeirosYeah, I can do that, but it is day by day only.07:47
SpeirosSo I'm having to change the days and search each one. I was looking for an easier way if at all possible ThinkT510, and I think it would be like you said, a grep command, but over a database or something.07:48
SpeirosSomeone once asked "How do I start Apache?" If I knew now what I knew then...07:50

St0nkBreadHello, all!10:53
lotuspsychjewelcome St0nkBread10:54
Elw3Heyo. Whenever i freshly booted, the word evict is in my clipboard. Anyone seen something similar?11:01
St0nkBreadthats spooky lol11:04
Elw3I want to know whats setting that.11:05
St0nkBreadI'm trying to list a group of files in the terminal. Files are -file00-09. The command cat ./-file0* returns the contents in a paragraph, and while I can get what I need from it, I want to sort the contents in a list, or something more readable.11:16
St0nkBreadI need to do this in the terminal, as I don't have permission to save the output to a file.11:16
St0nkBreadI keep thinking I'm on to something, and getting the ambigous redirect error. I've tried things like cat < ./-file0*11:18
St0nkBreadcat < ./-file0{0..9}11:18
St0nkBreadfile < ./-file0*11:19
Elw3create a list with ls, sort it, then cat each entry maybe.11:22

Pr_MoriartyI am not a super tech savvy guy, I am a student of political science interested in the politics of the open source movement however I feel I should at least try out FOSS software as a part of my research and I have heard Ubuntu is ideal for the tech novice within the FOSS community is this acurate?11:28
lotuspsychjePr_Moriarty: come to #ubuntu-discuss please11:30
St0nkBreadI got it!11:33
St0nkBreadI didn't figure out how to organize it with the cat command, but <!-- for x in {0..9}; do more ./-file0$x; done --> does an okay job of it.11:35
SpeirosWell done, St0nkBread :)11:44
St0nkBreadis there a way to get the path to show up in front of that content when using <!-- for x in {0..9}; do more ./-file0$x; done -->11:47
xtaocan't you just do more *-file0*11:47
xtaobasically the same thing11:48
St0nkBreadI was trying to write it like that, but was getting ambigous errors11:48
St0nkBreadi must've been writing it wrong, or taking the wrong approach, that does the trick in a new way!11:49
xtaothe *s expand so you are running "more file0 file1 file2" and then more takes care of showing you each file one at a time11:52
St0nkBreadyour suggestion is nicer to follow, because it ends up looking clean and showing which content belongs to which file11:54
St0nkBreadit does have to go screen by screen tho, where "for x in {0..9}; do more ./-file0$x; done" puts them in a list instantly, but it is not as organized, just listing the content with no other info11:55

deadromI got it now by heer luck spamming cursor keys on startup and now have recovery but no network. service network-amanger start does nothing17:13
tomreyndeadrom: indeed, hiotting escape is how you bring up the grub menu. cursor keys usually send a an escape sequence, so they can probably also trigger it.17:15
rfmdeadrom, if you can get to a shell in recovery mode, run "systemctl start multi-user.target" which will get you to a full console-mode session (but not start the dm)17:16
tomreynexiting from the emergency menu should also get you there, though17:17

llinguiniAny idea how to apply this theme?19:53
seeredionysus69: what does not work? What do you expect to happen?19:56
dionysus69seere:  I expect to execute "sudo /bin/systemctl status puma" without password19:57
dionysus69I did it in that past but it doesnt work for some weird reason19:57
dionysus69I am sure i am missing a small detail19:57
seeredionysus69: order matters IIRC. You should have this line AFTER the generic group based one which requires a password.20:05
dionysus69yea I put it at the end of file20:06
dionysus69I tried username matchers20:06
dionysus69also group matchers20:06
dionysus69still no luck20:06
stompykinsjust a quick question... i wrote my own .desktop file for a launcher (soulseekqt, if it matters) and the location of the Exec= and Icon= are on an external HD. id like to keep them there just in case but im just wondering why they dont show up in my menus after running update-desktop-database and even a reboot?20:14
stompykinsi copied the .desktop file to /usr/share/applications first of course20:14

dionysus69seere: ok I just added the file inside sudoers.d instead of directly editing /etc/sudoers, now it worked20:28
dionysus69but its weird anyways, it should have worked20:28
seeredionysus69: Not quite sure where sudoers.d gets included, but congrats to get it working ;)20:29
dionysus69seere: yea actually that's another strange thing, the line including sudoers.d inside sudoers file (last line) is commented out, but it still worked20:30
seeredionysus69: it isn't commented out, the keyword is actually named #includedir (the # is not a comment here...). Yes, sudoers has a strange syntax20:35
dionysus69seere: ok I guess that's it then :) ok thanks anyways and now you know whats up too xD20:36
MarkB2I have a old PATA hard drive and a computer not having a way to set cylinders/heads/sectors into the BIOS.  Anyone seen a driver for Linux that would accept a C/H/S setting and access this PATA drive?21:33
julius__found a file called swapfile in my home directory with the permissions: -rw------- 1 root root 10G Aug 18  2019 swapfile          but removing it as root says "operation not permitted"21:53
rfmjulius__, probably because the swap file is in use ("swapon" will list it.)21:54
julius__alright, i remember. i added that years ago22:06
jpmhI am a HUGE fan of the set -o vi option to bash.  Sometimes when I disconnect and then reconnect I do not get my expected history.  Where is it getting the wrong history from?22:25
slowly_stuckWhat's the easiest way to install 4.19 kernel headers on a Focal system? (I'm booting a 4.19.0 because it's a xen guest/domU)22:33
jeremy31slowly_stuck: get the headers from the same place you got the kernel from22:34
wolframHello, I have Ubuntu 16.04 running embedded in a certain device. This device communicates over the Internet with an Ubuntu 16.04 server. The server NIC's MTU is 9001 (jumbo frame) but the device's MTU is 1500. The device establishes a long running TCP connection to the server ..23:11
wolframperiodically, the device sends some data, which may or may not be morethan 1500 and the server responds to that with its own data, which is always low hundreds of bytes.23:12
wolframI am investigating why packages get dropped between the two systems and I am, unfortunately, unable to use tracepath from the device to the server to learn what the negotiated MTU is.23:13
wolframI also do not know what kind of switches or routers are between the two. My question is if I understand it correctly that MTU will be at most 1500 because this is what the device has? Unless something in between chooses a lower value, that is, but for sure not 9000?23:14
wolframThanks :)23:14
jpdswolfram: MTU isn't used across the internet like that, TCP uses the MSS23:14
wolframHm, MSS, let me educate myself some more in that case ..23:15
wolframAlright, I can see what it is, jpds - do you think the negotiated value should be visible in tshark dump captured on the server?23:17
jpdswolfram: Possibly, I just use `ss --tcp -i` myself23:17
wolframI just have a month worth of data and, needless to say, it occurs in about 1% of cases or less but when it does, it is really problematic.23:18
wolfram(I.e. I need to analyse past data)23:19
jpdswolfram: I would run mtr from the device to see where the packet loss is actually happening23:20
wolframI know, but unfortunately the device is quite locked without access to most commands. But reading about MSS it appears to be MTU less overhead of metadata, so it will be less than 1500 and I just need to find SYN/ACK in the Wireshark dump to confirm it..23:23
wolframAt any rate, not the jumbo frame.23:23
jpdsYeah, you need more data, sorry - TCP just doesn't random drop packets like this23:24
wolframOf course, nothing is random. At least not in programming.23:24
wolframjpds: By the way, I found in SYN/ACK that MSS was calculated to 8961 for the server and reading some more about, this is not a negotiation, rather being an announcement what the max. accepted length of payload is.23:41
wolframjpds: Not that it changes anything for now :)23:41
