[00:08] <casper34> Nope nope nope that is not true but okay just let it be. Going to figure out what to do
[00:08] <leftyfb> uh
[00:09] <casper34> and thanks alot for the help wishing everyone  great day
[00:09] <leftyfb> casper34: sorry, but it is true. LXD uses the same running kernel the host is and uses namespaces to separate out resources
[00:09] <sarnold> well, it's mostly true; docker and lxd's *container* things use the exact same kernel features when delivering vastly different views of containers.. but lxd can also do virtual machines, which docker can't do on linux
[00:10] <leftyfb> casper34: please do not PM
[00:10] <casper34> in the dm is why i asked just let it be
[00:13] <yates> how do i install the info pages for gcc?
[00:14] <leftyfb> yates: I'm pretty sure it's installed by default
[00:14] <yates> leftyfb: i don't see gcc.info.gz installed in /usr/share/info, where everything else seems to be
[00:15] <leftyfb> yates: just type:  info gcc
[00:15] <genii-away> Probably gcc-doc package
[00:15] <yates> leftyfb: that gives the man page
[00:16] <yates> i think info will serve up the man page for a topic if there is no info page for it
[00:16] <yates> genii-away: ok i'll take a look - thanks
[00:16] <Max-P> "info gcc" is giving me the manpage here yeah
[00:17] <yates> and the winner is... genii-away!
[00:17] <yates> thanks!
[00:17] <genii-away> Glad to assist
[00:19] <sarnold> $ apt-file search /usr/share/info/gcc.info.gz
[00:19] <sarnold> gcc-doc: /usr/share/info/gcc.info.gz
[00:20] <yates> sarnold: good reminder - i forgot about apt-file
[00:20] <yates> thank you
[00:20] <yates> i'll be glad when they make a DCI for SSDs
[00:25] <yates> genii-away: i thought the gnu assembler would be include with the gcc info page but it appears it is not. that is in binutils-doc
[00:26] <yates> thanks to sarnold i found it wihtout any hand-holding
[00:26] <sarnold> :D
[00:26] <genii-away> Self empowerment rules
[00:30] <yates> still hoping for a DCI
[00:31] <yates> i actually had apt-file documented in my personal ubuntu help. still forgot about it. ;(
[00:32]  * yates wonders who will be humble enough to ask what "DCI" means...
[00:32] <Croran> yates: what's a DCI?
[00:32] <yates> Direct Cerebral Interface
[00:33] <Croran> lol
[00:33] <Croran> like the OCZ thing
[00:33] <yates> OCZ?
[00:33]  * yates googles..
[00:33] <Croran> https://www.newegg.com/p/N82E16826100006
[00:34] <yates> is that a joke?
[00:34] <Croran> no it's real
[00:34] <Croran> youtube some reviews
[00:34] <yates> wow. queue Twilight Zone theme here..
[00:35] <Croran> I mean... people don't really understand the brain. So the OCZ NIA detects like... gamma waves and alpha waves or some such. And lets you assign them to buttons.
[00:35] <Croran> It's not like telepathy or something.
[00:36] <yates> i guess for now i'll have to stick with grep and my fingers..
[00:37] <yates> the apt-file thing gets away from me because i am first a fedora user, and have committed a bunch of dnf and rpm stuff
[00:37] <yates> ...to my head.
[00:37] <yates> rpm -ql "path-to-file"
[00:37] <Croran> apt-file? lol. i've literally never used that binary and been on ubuntu since 2008
[00:38] <yates> is there another way to do a "reverse lookup" of installed file to package name?
[00:38] <sarnold> yates: dpkg -S
[00:38] <sarnold> but that's only for installed packages
[00:38] <yates> is there something for any package, installed or not?
[00:38] <sarnold> that's apt-file
[00:39] <yates> Croran: soy ou've managed to live without this feature for 13 years?!?
[00:39] <Croran> hmmm well... ubuntu has a built-in thing.
[00:40] <yates> what?
[00:40] <Croran> if you try to start a binary that isn't on your system it automatically tells you which package has it.
[00:40] <sarnold> that only works for executables though
[00:40] <Croran> and i've used dpkg -S to look up info on files that are actually on my system
[00:40] <sarnold> handy though :)
[00:40] <Croran> so yeah. i've lived without that specific functionality i guess. i've used google to find package information on ubuntu's repo sites.
[00:41] <yates> well thanks everyone
[00:42]  * yates goes off to #emacs
[00:42] <sarnold> see ya yates
[00:42] <Croran> have fun
[00:43]  * yates waves bye
[00:54] <Croran> I keep getting this notification popup that says software updates are ready to be installed. it has, like, 4 buttons... 'ok' 'cancel' 'view' and 'update', as i recall.
[00:54] <Croran> anyway, when i hit 'view' nothing happens.
[00:55] <Croran> Is there a way to get rid of that pop-up?
[01:06] <Croran> i already tried removing execute permissions from the binary... notify-osd i think it was. problem is that gets rid of a bunch of other notifications too.
[02:17] <Tables> I seem to be having an error in both 20.04.3(current) and the daily 21.20 ISO installation where the keyboard selection screen after selected, comes up again slightly larger and won't continue past it again.
[02:31] <hhaglid> What is this?
[02:32] <hhaglid> Nevermind, that is a question a Google search can answer.
[02:44] <rob> I'm on my second Dell XPS laptop with Ubuntu 20.04 that has crapped out from apparent RAM failures: sudden freezes and crashes for no apparent reason, and the Dell RAM failure flashing light code often when trying to boot. With the first machine I just put it down to a hardware flaw. Now the same thing is happening with a completely new device, I'm wondering if there could be anything that I am
[02:44] <rob> doing, or Ubuntu is doing, that could affect this. Any thoughts?
[02:48] <lotuspsychje> rob: check your dmesg/journal logs to share with volunteers, so they can have a look
[03:08] <rob> Thanks lotuspsychje. I've actually been running OK for a bit now, so I guess nothing useful to see in the logs, but will make a note to do this next time the problem hits.
[03:09] <lotuspsychje> rob: you can also keep a journalctl -f running all day, see what happens at what time
[03:21] <rob> Actually, lotuspsychje I see it's possible to filter journalctl stuff by time, so here are logs from yesterday when I had a few of those freezes: https://termbin.com/zcpv
[03:22] <rob> https://termbin.com/dc1r
[03:24] <rob> I think there's so much in these journalctl logs termbin isn't taking it. Is there anything I can do to filter further? I don't have note of exact times of the failures.
[03:26] <rob> Are there specific things you would grep for, for example?
[03:30] <Bashing-om> rob: Like: ' journalctl -b |grep failed ' or ' journalctl -p 3 -xb ' to filter for errors.
[03:47] <rob> I was just talking about getting these freezes on here and then I had 2 in a row in a couple of minutes. Here is journalctl for the last 15 mins: https://termbin.com/jycn
[04:00] <Croran> rob: if your xps has ram sockets, reseat your ram. then run memtest86+ overnight to verify.
[04:00] <Croran> rob: not memtest86, but memtest86+. I believe it's included in the bootable Ubuntu image.
[04:04] <rob> Croran: thanks; I think the RAM is hard-wired into the motherboard on these things!
[04:05] <rob> Yeah, just confirmed that. It's soldered in.
[04:06] <rob> Do you think that means the motherboard is screwed? That's what seemed to be the case with my last machine. The current one is a replacement for that.
[04:06] <tsapien> Wow I thought one of the upsides tot he XPS was that it was upgradable RAM wise
[04:06] <Croran> memtest86+ is still relevant. it's completely independent of linux. essentially it's own OS.
[04:07] <Croran> that will tell you 99% whether you truly have a ram issue.
[04:07] <rob> OK, cool. So I'll boot from the image, run that and see what happens.
[04:07] <rob> Thanks very much for your help.
[04:07] <Croran> yeah. let it run for awhile. ideally overnight but at least a few hours
[04:07] <Croran> you're welcome
[04:12] <Bashing-om> rob: UEFI system then: http://www.memtest86.com/ <- proprietary offering; as UEFI is proprietary.
[04:14] <rob> OK, thanks
[05:52] <StopTheseFucking> I'm not good with Linux but i've got some hackers who are using my shit to mine bitcoin and they
[05:52] <StopTheseFucking> are having a blast.
[05:53] <StopTheseFucking> Help me stop them.
[05:53] <StopTheseFucking> I'd also like to take control of their mining for my own uses. My father is very ill and I need the money
[05:55] <StopTheseFucking> anyone?
[06:03] <TheBigK> StopTheseFucking: is this a joke or something?
[06:05] <StopTheseFucking> It's not.
[06:06] <Bojidar> irc.all4y.net
[06:07] <TheBigK> StopTheseFucking: do you have even ubuntu installed?
[06:07] <StopTheseFucking> Uh... Yeah.
[06:07] <TheBigK> which version... what exactly do you want to accomplish
[06:07] <StopTheseFucking> Well. First I'd like to stop them remotely acessing my computer.
[06:08] <TheBigK> do you know how they get in? Linux is actually pretty secure operating system
[06:08] <StopTheseFucking> They're using PPP or bluesnarfing
[06:10] <StopTheseFucking> Oh, and They
[06:10] <StopTheseFucking> are using google workspaces
[06:10] <StopTheseFucking> They're connected currently
[06:12] <StopTheseFucking> Shit.
[06:14] <TheBigK> can u pastebin netstat -anp
[06:14] <TheBigK> !paste
[06:22] <StopTheseFucking> 'm having some trouble
[06:23] <TJ-> StopTheseFucking: first thing you do is disconnect the PC from the network. Without that everything else is pointless
[06:45] <Croran> StopTheseFucking: How did these hackers get 'PPP' or 'bluesnarfing' set up on your PC to begin with?
[06:45] <Croran> StopTheseFucking: I'd suggest just shutting the system down and booting to an Ubuntu install CD - into the live desktop.
[06:48] <StopTheseFucking> Is therer no like, easy way to do this?This coputer was donated to me
[06:49] <alkisg> An easy way to remove "unknown malware put there by unknown means"? Sure, just reformat the donated PC
[06:50] <StopTheseFucking> I[06:50] <StopTheseFucking> sWell, that way they get away with it
[06:50] <alkisg> If there was an easy automated way to remove unknown malware, then antivirus programs wouldn't need to exist
[06:50] <StopTheseFucking> I don't carew how hard it is
[06:50] <StopTheseFucking> I wat to find them
[06:51] <alkisg> We don't care either, don't worry
[06:52] <Croran> alkisg: lol
[06:52] <StopTheseFucking> I mean, does no onSO, the world just is what it is?
[06:52] <Croran> StopTheseFucking: are you sober?
[06:52] <StopTheseFucking> sAs a fucking bird
[06:52] <StopTheseFucking> They've got it where i can't see what I'm typing
[06:53] <alkisg> It's like saying "I don't care how hard it is to treat coronavirus, aids and cancer, I just want to cure them". Sure buddy we'd like that too, but when something isn't possible, try to see what IS possible
[06:53] <Croran> here's a good tip for Ubuntu users. I learned this here. `dfc -Tt -squashfs` will give you a nice color formatted output of all your mount points and space and remaining space, without the stupid snap virtual disks cluttering it up.
[06:57] <StopTheseFucking> How do i see if thyere using Remminna?
[06:58] <alkisg>  Post the netstat output that they asked you before
[07:09] <StopTheseFucking> Uploaded file: https://uploads.kiwiirc.com/files/51b525b99d7b8dfd500238e8ad838771/pasted.txt
[07:13] <Croran> StopTheseFucking: that's not netstat output
[07:16] <user123> Hi
[07:16] <EriC^^> hello user123
[07:16] <Croran> user123: hi
[07:18] <StopTheseFucking> I'm in wiorkspaces.
[07:18] <Croran> StopTheseFucking: aren't we all
[07:39] <pevoz23> Hey there! I'm facing a bug with kernel 5.11.27: my system won't boot. I wanted to report the bug, but I can't find a way (if there's any) to access the log of failed boots. In /var/log I only found logs for successful boots
[07:42] <Croran> pevoz23: at what point does the boot fail?
[07:43] <sator> Hi, I'm considering to switch from LTS to interim; I've read the official wiki about the Ubuntu life cycle and also tens of articles here and there on internet about LTS vs interim but still I have a doubt about security when using an interim version for everyday activities. As most of the users (I think), 90% of installed software on my LTS box is
[07:43] <sator> coming from "main", the remaining 10% from "universe", so I'm bit concerned about the statement that interim releases only get security supports on "main". Does this mean that upgrades in "universe" for a interim might be unsafe or become a security issue? Can someone shed a bit of light on this topic?
[07:45] <alkisg> It means that if a package in universe has a known security issue and a fix for it, the fix may land on the LTS version but not on the non-LTS version
[07:46] <alkisg> For example, see some security issues there: https://ubuntu.com/security/notices
[07:46] <pevoz23> Croran: I'm not really able to answer, but quite at an early stage I would say. I just see a message "x86/cpu sgx disabled by bios, then a result from fsck on the root partition, after that it seems to enter a loop of the same messages (mainly related to talpa vfshook, i.e. related to the sophos AV). Then I have to hard shut down
[07:48] <alkisg> pevoz23: and the system boots with the older kernel? Which one is that?
[07:49] <pevoz23> alkisg Yep. Right now I'm using that system with 5.8.0-63-generic
[07:50] <alkisg> pevoz23: does sophos come with a kernel module, that it might be incompatible with kernel 5.11 yet? Can you disable it and see if it boots without sophos?
[07:51] <Guest9957> why KDE applications connect to internet whenever i launch them?
[07:51] <Guest9957> dolphin kate etc..
[07:53] <shortyy> hey, is there something comparable to tracker.debian.org for ubuntu packages?
[07:54] <alkisg> shortyy: the package information is available at https://launchpad.net/
[07:54] <shortyy> ugh, thanks. I think the ui is quite horrible for lp :/
[07:55] <user123> I am getting pseudo_Abort error when i run bitbake imx-image-multimedia
[07:55] <pevoz23> alkisg That could indeed very much be. I'll give that a try. I was actually more worried that a kernel update went wrong, as yesterday evening I came home and had no video signal out of the pc (it was running on the HWE kernel, so I guess already 5.11.x, where x<25or 27) and had to do a hard reset. However, then I sudo apt --reinstall'ed the latest
[07:55] <pevoz23> kernel with no better results. So i guess it could indeed be something related to sophos (and, if not, probably to nvidia)
[07:55] <user123> With multilib support this error
[07:55] <alkisg> shortyy: it has a lot of information there, code, bugs etc, it's not just package information, so it can be a bit confusing
[07:55] <sator> @alkisg: ah! So for LTS, if a package has a known security issue and a fix for it, the fix is provided immediately as update. Does it means that some "universe" packages for LTS 20 might be more updated than the same for LTS 21?
[07:55] <Croran> pevoz23: your system might not be booting to the point where it can write any logs. I think there's a way to boot your system to a serial output and log from another system.
[07:56] <Croran> pevoz23: i'm not exactly sure how it's done though.
[07:56] <Croran> pevoz23: oh here https://www.kernel.org/doc/html/v4.15/admin-guide/serial-console.html
[07:56] <alkisg> sator: no, not "immediately". It's just "more possible" that the fix will land in an LTS version, than in a non-LTS version. And usually this means "just the fix", not "a whole newer version that also has the fix"
[07:56] <pevoz23> Croran ok, thanks! Good to know. I'll do a research, then, if I'll need it :)
[07:57] <pevoz23> Croran ah, great, thanks!
[07:58] <Croran> pevoz23: you're welcome
[08:01] <Cool_Omar> Hi
[08:01] <Croran> Cool_Omar: Hi Mr. Cool
[08:02] <Cool_Omar> anyone succeeded to compile NDISWrapper from source?
[08:02] <Cool_Omar> Hi Croran
[08:03] <Cool_Omar> Need a fix for this
[08:03] <sator> @alkisg: thank you, now it is clear to me how it works; well, I'll consider it. My biggest issue with Ubuntu 20 is that my HP printer refuses to work, it was working perfectly on Ubuntu 18 but now is almost 1 year I have to struggle to print something (I need to use an USB key to transfer files on my old box with Ubuntu 18, or find a Windows box)
[08:03] <sator> and really I do not want to wait another year for the LTS upgrade that brings the newest version of HPLIP that might fix my issue...
[08:03] <Croran> Cool_Omar: why would we do that? it's available as a package
[08:03] <alkisg> sator: maybe work on that then? Which printer it is?
[08:04] <Croran> sator: which application are you typically printing from?
[08:04] <juliandroske> yes, but seems not requires CPUS to be installed in the package
[08:04] <Cool_Omar> Croran: to install some drivers that aren't working through normal package
[08:05] <shortyy> sator, i mean unconventional, but did you try the version from hp directly (for ubuntu)
[08:05] <shortyy> to see if a new version fixes the issue
[08:07] <Cool_Omar> Croran: here's a sample of my errors
[08:08] <Cool_Omar> Croran: /home/omar_mustafa/Downloads/ndiswrapper-1.63/driver/loader.c:157:4: error: too many arguments to function ‘__vmalloc’
[08:08] <Cool_Omar>   157 |    __vmalloc(load_driver->sys_files[i].size,
[08:08] <Cool_Omar>       |    ^~~~~~~~~
[08:09] <Cool_Omar> ./include/linux/vmalloc.h:132:14: note: declared here
[08:09] <Cool_Omar>   132 | extern void *__vmalloc(unsigned long size, gfp_t gfp_mask);
[08:09] <Croran> Cool_Omar: please don't paste multi-line errors in irc.
[08:10] <Cool_Omar> Croran: Ok but that's all my errors
[08:10] <Cool_Omar> Croran: Can u help?
[08:10] <sator> @alkisg: It is a HP Deskjet 3635 and connected to the USB
[08:11] <Croran> cool_omar: it appears to me that the latest ndiswrapper 1.63 source tgz does not include the latest svn changes from 2017.
[08:11] <sator> @Croran: I always use the same applications I was using with Ubuntu 18: evince, libreoffice... standard stuff, nothing new or special
[08:11] <Croran> Cool_Omar: i would suggest downloading the latest svn code and compiling from that
[08:11] <Croran> sator: chrome?
[08:12] <Cool_Omar> Croran: got link for that svn??
[08:12] <sator> @Croran: Chrome? No, thank you :)
[08:12] <Croran> sator: ok. just wondering because chrome printing stopped working right for me after my upgrade to 20.04.
[08:12] <Croran> Cool_Omar: it's on source forge, the same place you opened a issue ticket 4 days ago
[08:13] <sator> @Croran: However it does not work in any application in Ubuntu 20, while it works perfectly with all applications in Ubuntu 18
[08:13] <Croran> sator: understood. i just wondered if it were only an issue with chrome, as that was my experience.
[08:14] <alkisg> sator: how did you install the printer? Was it autodetected? What happens when you try to print? Is there any error message involved?
[08:17] <sator> @alkisg: The printer is autodetected, but I also tried to install it manually by CUPS; the error is the pretty (in)famous "Device communication error (5012)"
[08:18] <sator> alkisg: basically it does not work as printer and does not work as scanner
[08:18] <alkisg> sator, try this: sudo apt purge ippusbxd
[08:19] <alkisg> This daemon is supposed to provide ipp queues for driverless printing, but in many cases it's causing issues
[08:19] <alkisg> Then reboot; you might also need to remove/re-add the printer, but in my case it then worked immediately
[08:19] <alkisg> It's also one of the answers in a question about your error message: https://askubuntu.com/questions/1012562/device-communication-error-5012-hp-printer
[08:23] <sator> alkisg: Think I've tried that as well, but I'll try it again, thank you. I'm also checking by hp-check but output is useless because: warning: ubuntu-20.04 version is not supported. Using ubuntu-19.10 versions dependencies to verify and install...
[08:24] <sator> alkisg: so the whole output is useless
[08:24] <alkisg> You can check if you already purged the package with: dpkg -l ippusbxd
[08:25] <sator> alkisg: I have that package installed but I'm pretty sure to have tried that way - it is installed because when I try to fix something removing packages and see that does not work, I reinstall them
[08:26] <sator> but I'll re-try later, thank you
[08:26] <alkisg> Give it a try; see if it at least removes the error message. Cheers.
[08:33] <ubuntu> hello
[08:41] <Croran> Guest3848: hello
[08:43] <Guest3848> apt-get install hello wored
[08:43] <Guest3848> who are you
[08:44] <Guest3848> @Croran who are you
[08:45] <Croran> Guest3848: I'm Croran. Clearly.
[08:53] <sator> alkisg: It works! After one year struggling, it finally works! Where did you get that information about the ippusbxd daemon? I really tried all possible (reasonable) ways I found on internet without success, where did you find this?
[08:59] <alkisg> sator: I bumped into that issue a year ago, and it took me a couple of days to find it (and I'm a VERY experienced professional technician)
[08:59] <alkisg> So I noted it down as it was extremely annoying
[09:07] <sator> sator: Thank you, really. I'm experienced as well but as I print or scan very rarely I just googled it and tried the suggested fixes - at the end I was suspecting a hplip issue as the printer was properly detected but did not dig much into it as I do not print every day and had a "backup" solution (the old laptop)
[09:08] <sator> thank you, I'll take a note of this issue as well!
[09:08] <sator> @alkisg
[09:09] <alkisg> Cheers! :)
[09:12] <sator> alkisg: there is another issue that one day I really have to investigate, though; when I boot my Ubuntu 20 box, 9 times on 10 I get the GRUB shell prompt, I reset it and I could get it again and again or maybe I'll get the GRUB menu but it would not boot because "you must load kernel first"; after many attempts, resetting the box, I finally manage
[09:12] <sator> to boot it.
[09:13] <alkisg> sator, that's on BIOS or UEFI? Do you have multiple disks and/or grub installations?
[09:32] <supremekai> Hello! I have ubuntu 20.04 with the swap memory assigned to a partition. I'm not very familiar with this subject, but in my previous computer I was able to config swap using a swap file. Do u guys now any cool guide to increase swap memory using partition?
[09:34] <Croran> supremekai: ubuntu supports swap file too.
[09:34] <Croran> supremekai: you're wanting to increase swap memory? why?
[09:34] <supremekai> Croran, can I leave the swap partition and also add more with a file?
[09:34] <supremekai> I mean having the swap on both partition (already by default in ubuntu 20.04) + additional swap in swapfile
[09:34] <Croran> supremekai: not sure. I don't think I've ever seen a configuration like that.
[09:34] <alkisg> supremekai: what's the output of this command? (sudo parted -l; grep -i swap /etc/fstab; cat /proc/swaps) | nc termbin.com 9999
[09:35] <alkisg> You can have multiple swap files and multiple swap partitions etc, sure
[09:35] <supremekai> Croran, I have like 8GB of RAM and 1GB of swap, I can increase it right?
[09:35] <supremekai> alkisg, I'll check right away :P I'm at wind00z right now
[09:35] <supremekai> I'll turn up my computer with ubuntu
[09:36] <supremekai> but the swap is in a partition (didn't create it, probably assigned by default at ubuntu 20.04 install?)
[09:36] <supremekai> alkisg, thanks! So I can add a swap file too
[09:37] <supremekai> I'm kind of worried to mess it up, upon trying to assign more space to the swap partition
[09:37] <supremekai> I have no unallocated space
[09:37] <alkisg> Yes, although in some cases it doesn't make sense to add a whole lot of swap, it may not help as much as you think it will
[09:37] <supremekai> alkisg, I have 8 GB RAM and 1 GB of SWAP and I find my computer kind of slow
[09:38] <alkisg> You can resize partitions with a live cd and gparted if you want to increase the size of your swap partition
[09:38] <supremekai> How much swap do u think I can add up with 8 GB RAM?
[09:38] <alkisg> supremekai: yeah, swap doesn't make things faster. It makes things that are about to crash (out of ram), go slow instead
[09:38] <supremekai> I tried gparted, but I don't have unallocated space available
[09:38] <alkisg> You can resize existing partitions, to make space
[09:38] <supremekai> alkisg, yup, that snap store is the worst thing ever lulz I installed apps like a maniac
[09:39] <supremekai> shopping spree lulz
[09:39] <Croran> alkisg: assuming the swap is on a platter drive. swap on nvme won't slow crashing apps down that much. lol.
[09:39] <supremekai> I have nvme in that computer
[09:39] <Croran> i have 0 swap. no partition. no file.
[09:39] <supremekai> How much RAM?
[09:39] <Croran> 16gb
[09:40] <supremekai> idk I guess I installed too much bs from that snap store upon that shopping *free* spree
[09:40] <supremekai> I looked like one of those coupon ladies at the supermarket
[09:40] <Croran> what do snaps have to do with swap?
[09:40] <alkisg> Croran: the best nvme is order of magnitudes slower than ram, but that's not the main point; the point is that ram paging makes programs slower because they can't access their data directly
[09:41] <supremekai> Croran, I have too much apps running in the background, but no time to check it and clean it up
[09:41] <alkisg> `a = x[1]` needs one CPU instruction; paging needs millions of them
[09:41] <supremekai> my ram is always at 80%
[09:41] <supremekai> usage
[09:41] <ogra> thats what you want !
[09:42] <ogra> yu want your ram used ... why else do you have it 😉
[09:42] <supremekai> argo what do I want?
[09:42] <ogra> the more apps can operate in ram the better
[09:42] <Croran> alkisg: i'm aware nvme is a lot slower than ram. my point is that in the past swap often let you stop a crashing application before it ate all your swap space. today it is less likely to serve that purpose.
[09:42] <supremekai> I'm like those coupon ladies.. I like to save RAM
[09:42] <supremekai> lulz
[09:42] <ogra> this is not windows !
[09:42] <ogra> linux handles ram totally diferent
[09:42] <ogra> you want it all "used"
[09:43] <supremekai> but ubuntu is crashing like windows right now
[09:43] <alkisg> Croran: it's still an issue. systemd-oom is planned to try to help against crashes, so that only programs are closed instead of the OS crashing. But it's not "there" yet.
[09:43] <supremekai> I work with a lot of heavy stuff so it's always crashing up
[09:43] <ogra> how is it crshing exactly ... 8GB + 1GB swap seems fine, you should identify the apps that cause issues instead
[09:43] <supremekai> I have this Acer Nitro 5 AN515 for the ubuntu
[09:44] <supremekai> and it does not keep up
[09:44] <Croran> alkisg: what's the practical upshoot of that? are you saying swap is practically helpful today, even on an NVMe storage device?
[09:44] <alkisg> Croran: of course. E.g. you have 8 gb ram, you try to do something in gimp with a big image, it temporarily needs 12 gb => swap will be used instead of crashing
[09:45] <alkisg> There's no difference in that concept based on nvme, rotational or other storage technology
[09:45] <Croran> alkisg: okay. i guess i've never encountered a situation like that with 16gb of ram.
[09:45] <ogra> swapping will always make everything slow ... unless your sawp lives in a tmpfs in ram 😉
[09:45] <ogra> (but then you dont need swap 😛 )
[09:46] <alkisg> Croran: sure, if you never used more than e.g. 14 GB RAM, you won't have this issue. Me, with 16 GB RAM, I frequently have it, because I have 10 programs and 5 VMs open
[09:46] <ogra> ram is  accessed directly from teh CPU ... disks always go through a controller, a driver stack etc etc ... so even if your NVME is "as fast as ram" it cant be as fast
[09:47] <ogra> *cant be used
[09:47] <Croran> Does GIMP really crash if you load a file larger than RAM? It's not intelligent enough to stop malloc'ing?
[09:48] <alkisg> Gimp, chrome, linux in general, yeah
[09:48] <alkisg> Memory allocation in windows is better in that regard
[09:49] <ogra> supremekai, adding swap will only protect you from hard crashes but will not speed up a lot ... (as soon as your system starts to use swap it will slow down) ... identifying the apps you dont need and stopping them will be way more helpful than adding more swap
[09:49] <alkisg> (while caching is a whole lot better in linux)
[09:50] <Croran> supremekai: weird choice to buy nvme but only 8gb of ram.
[09:52] <sator> alkisg: it is UEFI, one GRUB, dual boot with with Windows and two disks (but Windows and everything but /home, /var and swap are on same "primary" boot disk - bottom line, the second disk is not used by the OS to work)
[09:52] <Croran> alkisg: I stopped using VMs on my main desktop because virtualbox was causing system instability. Do you use virtualbox?
[09:53] <alkisg> sator: this just adds some potential things that can go wrong; e.g. the UEFI selecting the wrong file or the wrong disk, so e.g. you may end up to a second grub.cfg that  you don't even know you have
[09:54] <alkisg> Croran: yes I've been using it for ages, it's excellent, no stability issues
[09:54] <Croran> alkisg: huh. with Windows VMs?
[09:54] <alkisg> Anyway, off for now, cheers, later...
[09:54] <Croran> alkisg: have a good one
[09:55] <sator> alkisg: thank you again, have a nice day!
[09:56] <alkisg> Croran: I have a windows installation in /dev/sda1 that I boot with virtualbox because I don't want to reboot. Yeah, that one is stable too
[09:57] <alkisg> (and when I do reboot, I can boot it without virtualbox as well)
[09:57] <Croran> huh
[09:57] <Croran> yeah i don't want to reboot either. i rarely use windows, but sometimes want it for testing.
[09:57] <alkisg> I also have some windows xp, 7 and 98. The 98 isn't stable, support for it has been removed a long time ago
[09:58] <ogra> technically support for all the versions you listed is gone 🙂
[09:58] <lavaball> can i print black and white? i'm guesisng i just have to add a color scheme or something. i'm not sure though.
[09:59] <Croran> lavaball: you've only been printing in color up to now?
[09:59] <lavaball> yes.
[09:59] <lavaball> well, if there was color in the thing i sent to the printer.
[09:59]  * alkisg also has around 30 linux distribution installations, for testing; these work fine too
[09:59] <Croran> lavaball: should be super simple. a setting in 'advanced' or 'settings' that says 'black and white' or 'greyscale' or something.
[09:59] <lavaball> but i would also like colored stuff to come out black and white sometimes.
[10:00] <lavaball> i looked, but it said no color schemes availabe or something.
[10:00] <alkisg> ogra: I meant support in virtualbox, not from microsoft...
[10:00] <ogra> ah ... 😄
[10:00] <alkisg> Windows 98 needed some weird compatibility code for their 16bit emulation or something, and they removed it
[10:01] <Croran> lavaball: have you looked in the printer properties from the printers panel?
[10:01] <lavaball> not yet.
[10:02] <Croran> lavaball: i think you'll find something relevant in the 'job options -> other options' section, though i only have a monochrome printer so your experience may differ.
[10:05] <lavaball> okay.
[10:05] <lavaball> thanks.
[10:27] <AsenM> Hello, in MySQL i'm doing set global log_queries_not_using_indexes = 'OFF'; but it still stays ON? Basically my command doesn't change it. Any ideas?
[10:46] <paul424> https://askubuntu.com/questions/154737/how-do-i-install-drivers-for-a-konica-minolta-200 I need to install K-M c224e ... Does the method in the link should suffice ? the device URI in my case would be lpd://192.168.1.120/print
[10:46] <paul424> assuming the IP is correct , what is LPD ?
[10:58] <bobdobbs> Hi. I'm trying to figure out the location of a script in my path. Usually I use 'which' for this. But in this case when I run 'which nvm' instead of getting a path back, what looks like a bash script gets printed to the terminal
[11:02] <EriC^> bobdobbs: can you share the output on a pastebin?
[11:03] <EriC^> bobdobbs: actually, try "type -a which" and "type -a nvm"
[11:10] <bobdobbs> output of 'type -a which'
[11:11] <bobdobbs> http://pastie.org/p/4PvdCpq5KQd8hh16uAoYHs
[11:11] <bobdobbs> output of the latter command: nvm is a shell function from /home/mantis/.nvm/nvm.sh
[11:11] <bobdobbs>  
[11:13] <EriC^> bobdobbs: what does '/usr/bin/which nvm' give?
[11:14] <bobdobbs> no return.
[11:15] <bobdobbs> ... which is odd. Because if I hit 'nvm' then I get output from nvm
[11:16] <EriC^^> which shell are you using?
[11:16] <bobdobbs> I think this might be the result of stuff I don't understand, related to how some of these tools install themselves in hidden folders in the home directory, and then install aliases to themselves... somewhere
[11:16] <bobdobbs> I'm using zsh
[11:17] <EriC^^> "type" seems to find it, wonder if it uses something other than $PATH
[11:18] <EriC^^> ah, type is a shell built-in, it must be something zsh related
[11:18] <EriC^^> what's the output of 'which nvm' anyways?
[11:22] <bobdobbs> It's too big to cut and paste from my text editor.  But if it helps, then here are the last lines: http://pastie.org/p/7ho5aECZYtrTnRSJ3wq0NK
[11:23] <EriC^^> seems like it's outputting the nvm.sh
[11:23] <bobdobbs> yes
[11:29] <EriC^^> bobdobbs: maybe try asking in #zsh
[11:55] <paul424> lotuspsychje, hello
[12:11] <BluesKaj> Hi folks
[12:17] <paul424> https://askubuntu.com/questions/154737/how-do-i-install-drivers-for-a-konica-minolta-200 I need to install K-M c224e ... Does the method in the link should suffice ? the device URI in my case would be lpd://192.168.1.120/print
[12:17] <paul424> assuming the IP is correct , what is LPD btw?
[12:18] <linsux> i dd entire ubuntu and failed to boot from new disk partition, is there way to fix it
[12:20] <EriC^^> linsux: was it uefi?
[12:35] <linsux> i fixed it with boot-repair
[12:36] <paul424> nobody answers so let me put it another way : Is the method in 'add printers' called 'enter uri' a valid one ?
[12:43] <asgas> I can switch from a regular release to lts easily right?
[12:48] <FNAShinobi> Running 20.04 and every day or two I have to disable my wifi and then enable it again because the speed goes down to 4Mbs. I usually get 100 Mbs from the wifi on this machine. As soon as I do that wifi re-enable it's back to 100 Mbs. Anyone have any ideas on what the problem may be?
[12:57] <rbasak> FNAShinobi: sounds like a driver or firmware issue. These things are usually specific to your particular hardware.
[12:57] <rbasak> It might also be an unfortunate interaction with your particular wifi access point.
[13:00] <FNAShinobi> rbasak: I don't think it's the access point, the other devices in the room are pulling 100Mbs. Do you know of a scenario where it's the AP and re-enabling the wifi adapter would correct? I can test to confirm it's working as it should
[13:00] <FNAShinobi> rbasak: If I want to install the intel drivers for the wnic, do I just copy the files in the firmware directory?
[13:02] <rbasak> FNAShinobi: note that I said _interaction_ with the access point. It's hard to pin an issue down to a specific bug in a particular device without some very time consuming debugging. But it's quite common to find that two different devices won't speak to each other well, but each device individually works with everything else.
[13:03] <rbasak> I can't answer your question about drivers. It depends on your specific hardware and what is available. Usually it's a route to trouble to be installing drivers from third party sources, though of course in your case it may be necessary to fix the issue. We'd prefer to fix the drivers that we ship.
[13:04] <rbasak> One other relatively easy route to work around a wifi issue is to get a USB wifi adapter that is supported well by Linux. For example most stuff that supports a "Raspberry Pi" will work well.
[13:05] <rbasak> Of course that's also inconvenient, but it is often way easier than messing with drivers.
[13:08] <hajonnes> My hdd:s are spinning even if they are unmounted several hours. I would like to let them to not spin up. I only rarely use them. @ubuntu 20.04. how do I set this setting?
[13:09] <hajonnes> I mean the best would be if they do not spin up even during boot. and I let them spin up if I mount them.
[13:48] <webchat88> Hey. I want to dual-boot windows with ubuntu in my desktop. But after reading some articles I'm having some doubts regarding partitioning, is anyone familiar with partitioning in dual-boot with windows?
[13:54] <webchat88> How saw in an article that if you do something like 4 or more partitions your disk becomes Dynamic, and reverting it back is not easy with windows installed. I didn't quit undertand it
[13:54] <webchat88> *I saw
[13:55] <DArqueBishop> webchat88: question. Why dual boot?
[13:55] <DArqueBishop> For most use case scenarios I'd argue virtualizing one of the OSes would be the easier and cleaner option.
[13:55] <webchat88> I installed windows literally just for games, the main OS I want it to be ubuntu
[13:56] <webchat88> Ubuntu because I think it has the most support regarding hardware...
[13:58] <webchat88> What if I had two ssd disks? Would I still have any problem?
[13:58] <webchat88> One for windows and other for ubuntu
[13:59] <alkisg> webchat88: you can dual boot with the same disk without any issues
[13:59] <mago> Hello im trying to make darknet, and it needs opencv
[14:00] <mago> I am in ubuntu 20.04 installed opencv through the command line, got opencv4.2
[14:00] <mago> But when making darknet i get: No package 'opencv' found
[14:00] <mago> How do i fix that?
[14:01] <webchat88> @alkisg I was about to install it, until I saw that thing about Basic/Dinamyc disk when having 4 or more partitions. I didn't get that
[14:01] <leftyfb> mago: please contact the maintainer of "darknet" for support building their software and it's requirements
[14:02] <alkisg> webchat88: are you on ubuntu currently? What's the output of: sudo parted -l | nc termbin.com 9999
[14:02] <webchat88> For example. I already have 3 for windows (created by windows itself), If I install ubuntu I would have problably more 3 or 4 (root, swap, home)
[14:03] <mago> leftyfb i am googling, contacting, asking in opencv, and also here.. If anyone knows it be great help..
[14:03] <mago> Really is more an opencv ubuntu issue than darknet..
[14:03] <mago> I think opencv through the ubuntu repository is not in the path,, so that makes it an ubuntu issue really
[14:03] <webchat88> @alkisg Nope, I installed Windows first, I saw it's better to install it first
[14:04] <leftyfb> mago: when you're building software, you usually need the associated libraries for it, not the binaries
[14:04] <alkisg> webchat88: can you boot from an ubuntu live cd?
[14:04] <leftyfb> mago: that said, contact the "darknet" maintainer for support about which libraries it requires
[14:04] <mago> Package opencv was not found in the pkg-config search path.
[14:04] <mago> Perhaps you should add the directory containing `opencv.pc'
[14:04] <mago> to the PKG_CONFIG_PATH environment variable
[14:04] <mago> No package 'opencv' found
[14:04] <alkisg> webchat88: in the BIOS/MBR mode, you can have up to 4 primary partitions; one of them can be extended that can have numerous logical partitions; and in UEFI/GPT mode, you can directly have numerous primary partitions. So no problem in either case
[14:05] <mago> Thats the issue, do you know how to add too PKG_CONFIG_PATH ?
[14:07] <Nuliel> Hello,
[14:07] <webchat88> @alkisg Yeah, just need to download the iso and burnt it to the usb. But what does that command do? Didn't find any info
[14:08] <alkisg> webchat88: that would show us if you're in MBR mode or in GPT mode, and what partitions you already have
[14:08] <alkisg> webchat88: in windows, the equivalent would be "upload a screenshot of diskmgmt.msc"
[14:12] <Nuliel> I have a question: I would like to retrieve the latest version number of ubuntu (for LTS and intermediate version, so for now "21.04" and "20.04.3"). the goal is to allow to update automatically the download site of iso https://www.ubuntu-fr.org/download/ . Is there a site that permits to just retrieve the latest version number? For now we parse
[14:12] <Nuliel> https://wiki.ubuntu.com/Releases but it's not good as it doesn't contain 20.04.3
[14:15] <webchat88> @alkisg I think I'm starting to understand, one storage device can have up to 4 primary partitions and each partition can be divided in sub-partitions? In windows I have a "C:", "Disk 0 Partition 1" and "Disk 1 Partition 4".
[14:15] <webchat88> I can do livemod ubuntu if that info isn't enough
[14:16] <BluesKaj> Nuliel, https://releases.ubuntu.com/
[14:17] <webchat88> My bad, *  "C:", "Disk 0 Partition 1" and "Disk 0 Partition 4"
[14:17] <Nuliel> thank you BluesKaj, I will parse this page instead of https://wiki.ubuntu.com/Releases
[14:23] <webchat88> @alkisg And  I'm using GPT in "Disk 0"
[14:31] <webchat88> Disk0 already has 3 primary partitions, so I was in MBR mode I could only do one more. But since it's in GPT there is no problem how many partitions I do?
[14:31] <webchat88> *if I was in MBR
[14:34] <alkisg> webchat88: exactly, you can have as many as you like
[14:38] <webchat88> Thank you so much for help! Just to confirm, the disk will stay "Basic"? And out of curiosity, I will make one partition for Ubuntu, so that will count as another primary partition. But when configuring ubuntu (when making the root, swap, home partition), that would be sub-partition of the "primary partition ubuntu"?
[14:38] <homura> ubuntu rocks
[14:38] <homura> arch sucks
[14:38] <octav1a> uwu
[14:39] <hajonnes> homura, why, I'm thinking of switching...
[14:44] <mago> Hello.. When i do: $whereis opencv.pc
[14:45] <mago> And it returns: $opencv:
[14:45] <mago> What does that mean?
[14:51] <leftyfb> mago: again, opencv is a library, not a binary/program
[14:51] <mago> leftyfb I get lost here, what you mean? It seems my program is looking for opencv.pc..?
[14:52] <webchat88> Check if this helps you, nice content: https://ss64.com/bash/whereis.html
[14:52] <leftyfb> mago: sudo apt install libopencv-dev
[14:52] <leftyfb> mago: you really should be taking the time to understand these sorts of things before going and creating a public "dark net"
[14:54] <mago> No, no.. Darknet is just a computervision program, is not as bad as it sounds.. Thanks leftyfb
[14:55] <mago> In linux they where suggesting config packages are not in the main library and we were trying to locate the right package.
[14:55] <mago> Actually leftyfb I alread installed libopencv-dev with python3-opencv
[14:57] <leftyfb> mago: libopencv-dev gives /usr/lib/x86_64-linux-gnu/pkgconfig/opencv.pc
[14:58] <alkisg> webchat88: they will be 3 primary partitions; the disk will stay basic
[14:59] <mago> Is it posible its giving opencv4.pc instead?
[14:59] <leftyfb> mago: what version of ubuntu?
[15:00] <mago> ubuntu 20.04
[15:00] <leftyfb> mago: ubuntu 20.04 installs libopencv-dev version 4.2.0+dfsg-5
[15:28] <mago> Ok, got it working in the end thanks leftyfb
[15:36] <enyc> Hrrm --  has anybody experienced  Signal-Desktop  on Ubuntu 20.04.x  updated  giving Blue window (except for menus)  and no longer  working,  e.g. maybe with nvidia-340 older video type ??
[15:42] <webchat88> @alkisg hmm, got it. Thanks for the help!
[15:59] <Guest6> can i rename the files in a .zip file without extraction?
[15:59] <Guest6> i can't extract it, because i think there's a probelm in the names
[16:01] <Guest6> the files names inside the .zip files have " * " character... linux wouldn't allow me to extract it
[16:01] <Guest6> also it wouldn't allow me to extarct files without extension :/
[16:03] <Guest6> oh nvm lol
[16:03] <Guest6> i can edit them INSIDE ark
[16:03] <Guest6> but not in dolphin exploring with ark
[16:48] <alkisg> Guest6: '*' is a valid file name in linux, e.g.: touch '/tmp/*'

[19:30] <hubwired> it's been a while since I was on IRC ...
[19:30] <matsaman> welcome back
[19:30] <tsapien> welcome back
[19:30] <hubwired> this covid  made everybody stayed away even from Cyber space...
[19:30] <matsaman> pretty sure it's done the opposite
[19:30] <hubwired> thanks mat, tsapien
[19:31] <matsaman> for those comfortable enough to still have cyberspace
[19:32] <hubwired> yeh @ mat, .. ;)
[19:33] <matsaman> hubwired: if you type 'mat' and then hit TAB, that'll probably help you
[19:34] <hubwired> thanks matsaman
[19:34] <hubwired> hehehe
[19:35] <hubwired> old habits die hard
[19:35] <hubwired> :)
[19:37] <hubwired> i have to re-install my local irc server so I can get my irc bots back and see if i have to update them
[19:37] <hubwired> before i'll try to use one of them...
[19:37] <matsaman> yes, you've got to
[19:38] <hubwired> unreal irc , is still good option for me ?
[19:43] <agners> Does somebody know who/what sets vm.min_free_kbytes in Ubuntu? I see vm.min_free_kbytes = 45056 on a Raspberry Pi with 2GB of RAM, there is nothing specifically setting it to that value in /etc/sysctl.conf and friends.
[19:51] <sarnold> agners: https://elixir.bootlin.com/linux/latest/source/mm/page_alloc.c#L8428
[19:51] <Guest4558> my Kde dolphin tries to connec tto interent when i open another Disk location, so i blocked it's access... now it freezed and won't open anything ;/
[19:52] <agners> sarnold: yes, that does not add up at all: the system 2GB memory, that should approximately equate to 5792k. But the value is almost 10 times as much
[19:53] <matsaman> Guest4558: blocked with what
[19:54] <Guest4558> matsaman: opensnitch
[19:54] <matsaman> Guest4558: so unblock it?
[19:55] <Guest4558> but why it wants to connec to tinternet, it should work fine without it
[19:55] <Guest4558> it's strange
[19:56] <sarnold> agners: hmm. strange.
[19:56] <matsaman> Guest4558: any network mounts it can see?
[19:56] <sarnold> agners: when my first guess was systemd, I found this jc package has some test output that shows exactly what you've got .. http://codesearch.debian.net/search?q=vm.min_free_kbytes&page=1
[19:56] <matsaman> anyway, there is probably more information you can get from the likes of opensnitch, to determine what remotely it is attempting to access and why
[19:57] <Guest4558> wait a second
[19:59] <agners> sarnold: oh interesting
[20:01] <Guest4558> it was trying to reach 127.0.0.1
[20:01] <Guest4558> dunno what's that
[20:06] <sarnold> Guest4558: that's localhost
[20:06] <TJ-> Guest4558: that is localhost, the address of the systems' lo loopback interface, which should always be reachable
[20:06] <TJ-> Guest4558: many local services talk to each other via ports on that address so you block it, you break them
[20:07] <Guest4558> so it's not an actual internet location
[20:07] <TJ-> far from it :)
[20:07] <Guest4558> will reenable then
[20:07] <Guest4558> thank you :)
[20:08] <Guest4558> btw all kde applications use the same manner,,
[20:27] <Cool_Omar> hi everyone
[20:28] <matsaman> hi just you ;)
[20:30] <Cool_Omar> Croran: I followed your advice and got the vmalloc error
[20:37] <Cool_Omar> Croran: note: declared here
[20:37] <Cool_Omar>   113 | extern void *__vmalloc(unsigned long size, gfp_t gfp_mask);
[20:40] <nergar> is there a way to get a file from a clonezilla backup? does anyone know?
[20:40] <nergar> i mean, an easy way... other than restoring the image somewhere
[20:40] <tomreyn> Cool_Omar: are you aware that ndiswrapper is a kind of last resort, but most of ther time it won't really help "solution"? are you really sure there is no better option? hwich chipset are you trying to get to work, on which ubuntu release?
[20:41] <Cool_Omar> tomreyn: Yes I'm sure
[20:42] <Cool_Omar> I just need a fix for the error I mentioned
[20:42] <tomreyn> nergar: i'm not sure which format the backup you have is, do you know? if it's a mountable image file you can loop mount it
[20:43] <tomreyn> Cool_Omar: i see. it's unlikley this will happen here, especially without more context (but sure, you can try).
[20:43] <nergar> its a clonezilla img, it is a folder with a bunch of files inside tomreyn
[20:43] <tomreyn> Cool_Omar: maybe there is an ndiswrapper channel?
[20:44] <Cool_Omar> tomreyn: where?
[20:44] <tomreyn> Cool_Omar: on one of the larger IRC networks. i don't know, just wondering.
[20:45] <Cool_Omar> tomreyn: It's for my RTL8822BE Bluetooth Which I tried everything with no luck at all
[20:45] <tomreyn> nergar: "img" sounds more like a single file?
[20:46] <Croran> Cool_Omar: that's not an error. that's a line number and a function declaration. paste your error to pastebin and link it.
[20:46] <Croran> Cool_Omar: so you downloaded the latest svn code and you're trying to compile that?
[20:47] <nergar> tomreyn, yes, clonezilla uses the term "image" and creates saves it under a folder ending with -img but the actual mess looks something like this https://www.ubackup.com/screenshot/en/others/clonezilla/clonezilla-image-file.png
[20:49] <Cool_Omar> Croran: Yes I downloaded it and https://paste.ubuntu.com/p/9Vt4MK5My8/
[20:50] <tomreyn> nergar: i see, those are gzip compressed partition images. which of those are you trying to access?
[20:52] <nergar> ahh I see
[20:52] <nergar> my / partition
[20:52] <nergar> im guessing mmcblk0p1.vfat-ptcl-img.gz is my EFI partition and the mmcblk0p3.btrfs-ptcl-img.gz.aa files are my /
[20:53] <tomreyn> nergar: those aren't on the screenshot. but that could be.
[20:56] <crazyfrog> where can i get help with phpmyadmin and mysql?
[20:58] <tomreyn> nergar: the '.aa' in 'mmcblk0p3.btrfs-ptcl-img.gz.aa' suggests that this is a multi-part (gzip) archive. you will probably need to reassemble it and decompress it to be able to loop mount it.
[20:58] <tomreyn> https://unix.stackexchange.com/questions/219142/mounting-a-btrfs-image-file#answers should work against the reassembled, uncompressed, btrfs image - i assume.
[20:59] <tomreyn> crazyfrog: depends, is this phpmyadmin and mysql on a supported ubuntu release?
[21:00] <crazyfrog> yes
[21:01] <crazyfrog> mysqli::real_connect(): (HY000/2002): No such file or directory
[21:01] <crazyfrog> from phpmyadmin
[21:02] <tomreyn> crazyfrog: what's the output for   cat /etc/os-* /proc/{version*,cmdline} | nc termbin.com 9999
[21:02] <cloudcell> hello, I cannot install cuda development libraries on ubuntu 20.04, the error says that I hold broken packages, but I see that I don't have broken packages:
[21:02] <cloudcell> in synaptic
[21:03] <cloudcell> https://www.irccloud.com/pastebin/K9Xw1dJE/
[21:03] <cloudcell> can anyone help me?
[21:03] <Cool_Omar> +
[21:04] <tomreyn> cloudcell: use apt:   sudo apt update && sudo apt -f install && sudo apt --simulate -Vy full-upgrade
[21:04] <cloudcell> thanks tomreyn , let me try that
[21:05] <Croran> Cool_Omar: huh. well looks like a different error at least, no?
[21:05] <ozzloy> test
[21:06] <tomreyn> cloudcell: i had not yet seen the message you posted. it says that     package "cuda-11-4" is not available in version 11.4.1 or greater from your currently configured apt repositories. you can check which version of it is availbale using:   apt policy cuda-11-4
[21:06] <Croran> cloudcell: what is your output for `sudo apt-mark showhold` ?
[21:06] <tomreyn> ozzloy: for tests, please    /join #tests
[21:07] <cloudcell> https://www.irccloud.com/pastebin/8DwhrsDU/
[21:07] <ozzloy> tomreyn, lol, that's awesome there's a channel specifically for that.  thanks for letting me know
[21:07] <cloudcell> https://www.irccloud.com/pastebin/3BnAecuk/
[21:08] <cloudcell> the output for "sudo apt-mark showhold" is nothing
[21:08] <Croran> huh
[21:10] <wheatstonebridge> Hi all!  I'm working with NetworkManager and ModemManager.  NetworkManager should kick off ModemManager after it sees that there is a valid /dev/cdc-wdm0 device.  That is not happening in my case.  I can connect with modemmanager and it works fine.  But I can't get NetworkManager to initiate the connection.  I also never see a /dev/wwan0 device.
[21:10] <wheatstonebridge> Does anyone know what is responsible for launching ModemManager from NetworkManager (or whatever else I'm missing)??
[21:10] <cloudcell> tomreyn: so nothing helped me so far, I put the output in snippets above
[21:11] <tomreyn> cloudcell: according to https://www.irccloud.com/pastebin/8DwhrsDU/ you have a PPA configured for the "stacer" software, but this PPA does not provide packages for your Ubuntu release (20.04 LTS = "focal"). You can also see this here - no "focal": https://launchpad.net/~oguzhaninan/+archive/ubuntu/stacer
[21:13] <tomreyn> cloudcell: this is an error you should solve, probably by removing ths apt repository. but it is probably not the cause for the problem with the cuda package. according to https://www.irccloud.com/pastebin/3BnAecuk/ there is a "cuda-11-4" package available in version "11.4.1-1" - which I think does match the "version 11.4.1 or greater" requirement. so there can be another problem preventing installation of this package.
[21:14] <Starmina> Hello everyone, i have a tons of "kernel: audit:" logs in syslog. I tried to tweak /etc/rsyslog.d/50-default.conf to remove those to no avail. It drives me crazy. Some search on Google talk about some files in /etc/audit/... to tweak but I have no such files. And I don't even have a /var/log/audit file ! The default 50-default.conf shows nothing about audit. I don't even have any package related to audit appart from "libaudit". I randomly tried to add
[21:14] <Starmina> "audit.none -/var/log/syslog" but of course, this doesn't work. Removing the first line in 50-default.conf (with *.* -/var/log/syslog) indeed stop "kernel audit" messages from showing up as well as any other logs, which is not the behaviour i'm looking for. My last hope is to ask here, i feel sorry :| usually Google work for me.
[21:14] <tomreyn> cloudcell: what happens when you try to install "cuda-11-4" directly?
[21:14] <Croran> cloudcell: maybe try `sudo apt install --ignore-hold cuda`
[21:15] <cloudcell> let me try
[21:15] <cloudcell> thanks Croran
[21:15] <cloudcell> https://www.irccloud.com/pastebin/PbvPNPLX/
[21:15] <Croran> Starmina: yeah i also find that debugging type syslog messages are super annoying
[21:16] <Croran> starmina: and i've tried researching ways to filter them out too. actually i seem to recall once i actually modified and recompiled a kernel driver in freebsd just to get rid of its debug messages.
[21:17] <tomreyn> Starmina: those "audit" records are often related to apparmor 'violations'. and those are often triggered by badly crafted snaps.
[21:17] <Croran> Starmina: if you find a good way to filter them i'd like to know too.
[21:18] <Max-P> you can disable those by booting with `audit=0`
[21:18] <tomreyn> is this the right approach, though?
[21:18] <Croran> Max-P: adding a kernel command line in grub?
[21:19] <tomreyn> better identify the software triggering them and find a fix for it, or an alternative
[21:19] <Croran> personally i'd like to filter them down to a single line for repeats. the way the USB error messages get 'compressed'.
[21:19] <cloudcell> https://www.irccloud.com/pastebin/9tkvhhyY/cuda-installer.log
[21:20] <cloudcell> tomreyn: ^^
[21:20] <tomreyn> Croran: i'mnot sure whether rsyslog rate limiting works for kernel messages or not (my gut feeling is "not").
[21:20] <Croran> cloudcell: seems like you downloaded the cuda install script and ran that? can you try downloading the cuda deb package and install it with dpkg?
[21:21] <tomreyn> cloudcell: what am i looking at there?
[21:21] <cloudcell> https://www.irccloud.com/pastebin/68VLMA9U/nvidia-installer.log
[21:22] <Croran> cloudcell: i wouldn't expect the nvidia-provided install script to work on ubuntu. it might, but i wouldn't expect it to.
[21:22] <cloudcell> tomreyn: I posted the output
[21:22] <tomreyn> cloudcell: of?
[21:22] <Croran> cloudcell: download this and try to install it with dpkg  - https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2004/x86_64/cuda-11-4_11.4.1-1_amd64.deb
[21:23] <cloudcell> of installing cuda directly
[21:23] <cloudcell> Croran: doing this now
[21:23] <tomreyn> cloudcell: i guess you better work with Croran this one, i'm not really much into nvidia lands. good luck!
[21:24] <Croran> tomreyn: i think i'm just explaining what you wanted him to do. lol
[21:24] <cloudcell> thanks tomreyn !
[21:24] <Croran> in my experience, nvidia provided driver install script doesn't work on ubuntu since, like 16.04...
[21:25] <Croran> The 'ubuntu way' is to install the deb packages.
[21:25] <tomreyn> Croran: i'd expect this, too. i was trying to first get full understanding of what cloudcell actually ran to produce that output, but it seems you guessed right - upstream installer.
[21:26] <cloudcell> Croran: it fails to install it says that 'the following packages have unmet dependencies:'
[21:26] <cloudcell> and then does not list any packages at all
[21:26] <Croran> cloudcell: this seems likely to be a common issue. what did google say?
[21:27] <Cool_Omar> Croran: no How it's a different error?
[21:27] <Croran> cool_omar: isn't it a different error compared to the error you were getting when you tried to compile with the other version?
[21:28] <cloudcell> Croran: https://www.google.com/search?channel=fs&client=ubuntu&q=The+following+packages+have+unmet+dependencies%3A++nothing
[21:28] <Croran> cloudcell: dumb search
[21:28] <Cool_Omar> Croran: it's the same one
[21:28] <Croran> cloudcell: https://duckduckgo.com/?q=ubuntu+20.04+cuda+problem+held+packages&ia=web
[21:28] <cloudcell> last time i came across this issue, i ended up reinstalling the os
[21:29] <Croran> Cool_Omar: oh.. ok. i didn't reliably remember what the old error was. anyway. the notes on the latest svn update from 2017 seemed likely related to the problem you were encountering.
[21:29] <Croran> Cool_Omar: so sorry it didn't help.
[21:30] <Croran> cloudcell: have you tried 'sudo apt install nvidia-cuda-toolkit' ?
[21:30] <cloudcell> trying this now: https://forums.developer.nvidia.com/t/error-with-cuda-repository-on-ubuntu-20-04/188023
[21:31] <Cool_Omar> Croran: I need a patch @ least
[21:31] <Starmina> Well for kenrel audit message I have messages when login trough ssh with things like msg='op=PAM:setcred grantors=pam_permit" etc... but I also have that everytime cron execute etc... It seems werid to add audit=0. I would just like to filter those message in /var/log/audit (for example)
[21:31] <cloudcell> will try sudo apt install nvidia-cuda-toolkit, Croran
[21:31] <Croran> i mean, ubuntu is one of the main, if not the main supported OS for nvidia cuda.
[21:31] <cloudcell> on my mx linux everything works perfectly, Croran
[21:32] <Croran> should be many people experiencing that issue, unless there's something you've specifically broken on your system
[21:32] <cloudcell> well, let's see how this toolkit gets installed
[21:32] <Starmina> I don't even know when those message starting to appear
[21:32] <Starmina> On my other Raspberry on Ubuntu 20.04 i don't even have "audit" messages at all
[21:33] <Starmina> This one is on 21.04
[21:33] <crazyfrog> tomreyn, i have to (re-)install the container
[21:33] <tomreyn> Starmina: you could share some of the messages you would like toget rid of. that would possibly enable folks here to help you out.
[21:33] <Starmina> Well, of course
[21:33] <tomreyn> Starmina: on a pastebin, of course
[21:34] <nergar> tomreyn, thanks ill check that
[21:34] <Starmina> Sep  2 23:34:01 raspberry kernel: [13399.403258] audit: type=1300 audit(1630618441.840:4171): arch=c00000b7 syscall=64 success=yes exit=1 a0=7 a1=ffffca140490 a2=1 a3=ffffb6472010 items=0 ppid=1733 pid=87891 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=542 comm="cron" exe="/usr/sbin/cron" subj=unconfined key=(null)
[21:34] <nergar> sorry, i had to attend something
[21:34] <Starmina> For example. (lol)
[21:34] <Croran> Cool_Omar: does the SVN version you downloaded have the proper #include <linux/vmalloc.h> line at approximately line 23 of the driver/loader.c file?
[21:34] <Croran> Starmina: nice pastebin
[21:35] <Starmina> And there' is a TON of these, each time I login, logout, etc.
[21:35] <Croran> tomreyn: here's the ones i get https://pastebin.com/a8CTYduu
[21:36] <cloudcell> Croran: the toolkit was installed perfectly
[21:36] <cloudcell> but the cuda version is 10 (in the toolkit)
[21:37] <Starmina> Exerpt of syslog :
[21:37] <Starmina> https://pastebin.com/9k6u4ZmF
[21:38] <Croran> cloudcell: nice.
[21:38] <Cool_Omar> Croran: @ line 24 #include <linux/vmalloc.h>
[21:39] <tomreyn> Croran: those are snaps which get access denials to some place on the file system4, i guess
[21:40] <Croran> cloudcell: looks like to get version 11 on 20.04 you'll need to use a manual install process. 20.10 has a package for version 11 if you want to upgrade your os. https://askubuntu.com/questions/1288672/how-do-you-install-cuda-11-on-ubuntu-20-10-and-verify-the-installation
[21:40] <Croran> Cool_Omar: ok. well that's good. that line wasn't there on the latest .tar.gz source package.
[21:41] <Croran> Cool_Omar: have you considered going back to an old version of ubuntu that is verified as being able to compile ndiswrapper?
[21:41] <Croran> cool_omar: as a test.
[21:41] <cloudcell> thanks Croran , I will read this
[21:41] <Cool_Omar> which one?? Croran
[21:42] <tomreyn> Starmina / Croran: https://wiki.archlinux.org/title/Audit_framework discusses how to more selectively filter messages. Starmine has a different audit record type than the usual snap triggered ones, though, 1300
[21:42] <Croran> cloudcell: the last response there i think is the relevant one.
[21:42] <Starmina> Well I have removed snap entierly from my system so that can't be from snap for sure
[21:43] <Starmina> auditctl
[21:43] <Starmina> oops
[21:43] <Croran> cool_omar: I'd suggest 12.04 since it looks like that was the most current version mentioned in the official ubuntu docs for ndiswrapper
[21:43] <Croran> Cool_Omar: https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper
[21:44] <tomreyn> Starmina: it seems to be from snap-store in your case. which is a snap.
[21:44] <Starmina> hmm okay
[21:44] <tomreyn> Croran: let's not recommend EOL releases please ;)
[21:45] <Croran> tomreyn: well it's less of a waste of time than trying to get ndiswrapper to compile on 20.04, and if he can verify ndiswrapper doesn't help anyway, then issue solved. :)
[21:46] <tomreyn> it might be better to try one of the git repositories providing drivers for this thing right away. or just replace it by something that's less picky
[21:46] <Croran> tomreyn: yeah i wonder what the hardware even IS
[21:46] <tomreyn> s/less picky/has vendor support on linux/
 tomreyn: It's for my RTL8822BE Bluetooth Which I tried everything with no luck at all
[21:48] <Cool_Omar> exit
[21:48] <Croran> tomreyn: ah nice. aren't bluetooth dongles like $2 now?
[21:49] <Cool_Omar> quit
[21:49] <tomreyn> Croran: not the current ones, i think. and certainly not everywhere
[21:58] <Starmina> It seems it'll be more easy to just reinstall my raspberry pi :/
[22:07] <robin_> Hi everyone, Robin here
[22:11] <Croran> Hi Robin. Croran here.
[22:13] <Croran> tomreyn: the arch article about filtering audit messages talks about editing a file in /etc/audit/rules.d/. i don't even have a /etc/audit. let alone a /etc/audit/rules.d
[22:14] <sarnold> install auditd?
[22:16] <morgans> bluetooth dongles that work with linux. I have been looking on Amazon and they run fomr 6 to dunno $35 and each one has a but about it, imho. Where should I look for one?
[22:17] <Croran> morgans: if i needed one and wanted reliable i'd probably go with the asus usb-bt500. asus actually distributes a linux driver and it appears people have had good experiences with it.
[22:17] <Croran> morgans: another option is there's a 'panda' brand that is supposedly designed just to be compatible with linux
[22:18] <morgans> Ill check on that right now. Thanks Croran
[22:19] <morgans> $14 - I am in.
[22:20] <Croran> morgans: what are you actually going to do with it? wireless stuff on a desktop is more hassle than it's worth IMO.
[22:20] <Croran> sarnold: ah. good call.
[22:21] <sarnold> linux bluetooth is notoriously poor, it could be that the dongles are fine and the software is the problem
[22:21] <morgans> I am going to connect a keyboard and lalso a speaker (for now)
[22:21] <morgans> Croran,
[22:22] <WaV> My AirPods work great with my laptop, suprisingly (since they're an Apple product).
[22:22] <sarnold> WaV: do they also work as headset, with microphones working?
[22:22] <Croran> morgans: your keyboard battery is going to die at the worst time and you're going to miss something important while you're scrambling for batteries.
[22:22] <sarnold> I spent an hour or so one day trying to make airpods work and gave up :)
[22:22] <Croran> morgans: you're going to have to plug your speaker in to charge it anyway. lol.
[22:23] <WaV> sarnold: I haven't tried the microphone part, but yes they do work as a headset.
[22:23] <morgans> my keyboard worked fine with the logitech dongle
[22:25] <WaV> sarnold: I'll let you know. Downloading GNOME sound recorder.
[22:26] <sarnold> WaV: woot
[22:27] <morgans> my keyboard worked fine with the logitech dongle Croran  5 reviews mentioning linux worked, 2 failed.
[22:28] <Croran> morgans: not saying it won't. just saying you're reliant on batteries. another point of failure.
[22:29] <Croran> morgans: my keyboard theoretically works forever.
[22:29] <Croran> sarnold: sweet. got my auditd rules going and apparently working correctly.
[22:30] <sarnold> Croran: yay :)
[22:32] <Croran> sarnold: hmm. now that said... i filtered based on msgtype 1326 and msgtype 1400 and it appears those resolve to 'AVC' and 'SECCOMP' rules, which leaves me wondering what else i filtered beyond broken snap action.
[22:35] <morgans> well, thank. I should search through "my stuff" and see if I can find one. for the kb only but that will be nice. The kb has a touchpad.
[22:47] <WaV> sarnold: It doesn't appear to work as a microphone... at least natively anyway.
[22:47] <sarnold> WaV :(
[22:47] <sarnold> WaV: thanks for giving it a try
[22:51] <WaV> I didn't have a need for it before. Now I'm probably going to spend the next couple days scouring the Internet for a work-around, lol.
[22:52] <sarnold> even in the best case that you manage to get it to work, it'll fallback to a bluetooth protocol that is worse than you'd get connected to an android or ios or macos or windows peer :(
[22:55] <WaV> sarnold: Ah, oh well. Thanks for the heads up
[23:14] <WaV> sarnold: This is a limitation of Pulseaudio, right?
[23:17] <sarnold> WaV: or bluez, I'm not sure which
[23:18] <WaV> sarnold: Wonder if it'll get improved upon in the future. Oh well, time to head out.
[23:20] <sarnold> WaV: I hope so. have a good night :)
