[00:02] <pirx> hi! i get errors when trying to upgrade 18.04 -> 20.04. do-release-upgrade ends up saying "could not calculate..." and in apt.log i see errors about the package python-is-python2: https://pastebin.com/67teZ9ZU  but according to dpkg etc i dont have that package installed, and it doesnt seems to exist to me according to apt
[00:03] <pirx> i have searched the web and see other people have similar problems, but i havent found any suggestions. anyone here? :)
[00:05] <tripelb> sarnold can I ping fromy computer
[00:05] <sarnold> pirx: try dpkg --get-selections | grep python2
[00:06] <tripelb> (Sorry for the lag I got a phone call. sarnold
[00:06] <sarnold> tripelb: yes, ping 192.168.0.3 or whatever
[00:06] <sarnold> tripelb: look up the ip address of your computer with 'ip a' before it hangs, so you know what address to ping
[00:08] <pirx> sarnold: yepp, no python-is-python2 there either, only python2.7 and python2.7-minimal
[00:09] <sarnold> pirx: strange. I wonder why it got dragged in in the upgrade computations :(
[00:10] <sarnold> pirx: it's probably worth a bug report; ubuntu-bug do-release-upgrade should get you started
[00:11] <tripelb> sarnold i used <hostname -I>   because I couldn't figure out what the output of <ip addr show> or <ip a> meant. My ip is .... Is there any reason not to just tell you here? I don't want to be dumb, well dumber than I am.
[00:12] <tripelb> I sent it to my phone and I'm searching how to ping.
[00:12] <pirx> ......dpkg-query: no packages found matching do-release-upgrade  ...  The problem cannot be reported: This report is about a package that is not installed.
[00:12] <pirx> something is horribly wrong? :)
[00:13] <sarnold> pirx: ugh. I thought ubuntu-bug would look up the owning package :) try ubuntu-bug /usr/bin/do-release-upgrade
[00:14] <sarnold> tripelb: ipv4 addresses are almost always 'private' to a local LAN, I bet 99% of folks in here have an IP on their desktop that's like 192.168.0.7 or something :)
[00:15] <tripelb> 192.168.1.126
[00:16] <tripelb>  ping -c 192.168.1.126    was not good enough. Domain??   Sarnold
[00:17] <tripelb> I left domain blank so it spin out a bit of the man page sarnold
[00:17] <tripelb> SpiT
[00:18] <sarnold> tripelb: skip the -c
[00:18]  * tripelb breaks step and remembers how ubuntu used to work outofthebox before 2012
[00:19] <tripelb> seednodeo  <ping 192.168.1.126>
[00:21] <tripelb> OK works sarnold as low as 2.77 but mostly around 15 and as high once as 21
[00:21] <sarnold> tripelb: cool. now, when it hangs, find out if it's still responsive or not :)
[00:21] <sarnold> tripelb: getting an ssh to work would be very helpful, if it does, then you might be able to fix the problem remotely
[00:22] <tripelb> Sarnold I had to install "terminal emulator" app. (This did not used to exist the last time I tried to SSH. This one looks simple. That was maybe two three years ago.)
[00:22] <tripelb> Sarnold It's actually still responsive but it's so slow nothing happens. I have been able to tell that some of the times that it hangs.
[00:24] <sarnold> tripelb: aha, excellent; that suggests something like a kernel memory leak. keeping an eye on sudo slabtop output over time might be useful
[00:32] <pirx> sarnold: bug reporte! thanks!

[02:07] <sarnold> tripelb: waaaaaat?? that's insane :)
[02:07] <tripelb> I can live with it
[02:13] <tripelb> Sarnold. I notice that on hexchat.hexchat is weird. let me check og it is yhe same in the text program
[02:14] <tripelb> Fine. It is just hexchat. I am looking for an alternative
[02:18] <sarnold> tripelb: hmm, I've been using irssi for almost twenty years now.. I've been on the fence about trying out weechat. I think it has more features, more easily available, but takes more memory and may not be able to handle as much irc as I do..
[02:18] <sarnold> tripelb: but both are pretty far departures from hexchat :) hehe
[02:20] <tripelb> Anyone, I am considering The Lounge "modern irc client BUT it wants me to install node.js -> and that sounds like Win to me. So I will ask before installing.
[02:21] <tripelb> I think pigin was missing replay of previous lines or logging or some normal thing. Nick completion. There are a short list of features.
[02:22] <tripelb> Sarnold node.js ?
[02:42] <sarnold> tripelb: i've heard good things about THe Lounge but it's clearly not for me :)
[02:43] <sarnold> tripelb: installing node.js is probably just 'sudo apt install nodejs'

[05:50] <viktor_> hi al. i'm trying to copy files from a mounted encrypted folder (using vaults in KDE) to my home server. used Fillezilla and regular sftp. But i can't seem to copy anything. anyone can help me out?
[05:53] <Tabmow> viktor_: does it work via the cmd line?
[05:58] <viktor_> Tabmow: nope. i can ssh into the required folders. but sftp doesn't work. i think it might be a permissions problem though.
[06:00] <viktor_> Tabmow: that's what is was. i chmod the target folder to 777 and it works. just have to familiarize myself with groups and permissions to have more elegant solutions :)

[08:26] <superschnell> Hi all. I was wondering: if you have a repository, and you see packages for e.g. bionic, but within that, you see various versions, from 1.0, 1.5, 2.0 to 2.5 and "nightly". This resolves to e.g. deb.repo.org/pool/bionic/nightly/... etc  ... how can I select the "nightly" version specifically?

Just say it isn't found.
[08:37] <superschnell> Just says*
[08:41] <superschnell> Hmmm, I modified /etc/apt/sources.list.d/foreman.list and changed deb http://deb.theforeman.org/ bionic 2.0 to: deb http://deb.theforeman.org/ bionic nightly

[10:08] <lotuspsychje> ask your specific question to the channel P-NuT so volunteers can think along with you
[10:09] <P-NuT> Oh right, I am looking at using Modsecurity on ubuntu, but it seems a faff to use it with NGINX, whereas it seems easier to use with apache. I was wondering if anyone had any personal stories of running either in production that could advise.
[10:11] <P-NuT> might be a better question for the nginx channel though...

[11:53] <pirx> can i manually look into this somehow? like, where are the DBs/lists of what packages the system possibly thinks it has?
[11:55] <pirx> i'd like to just nuke-purge it somehow and do the upgrade, and hope that 20.04 will have all the packages it needs:)  (also, i just bumped the server from 16.04 to 18.04)

[12:49] <PCatinean> I am runnint a VM and do df -h where I see < 50% disk usage, yet when I try to do touch test.txt it says no space left on device
[12:49] <PCatinean> How can this be?
[12:50] <hggdh> PCatinean: check inodes usage: df -i
[12:50] <PCatinean> hggdh, that is indeed 100% what is that? :O
[12:58] <hggdh> PCatinean: inodes are used to store file information. Each file has an inode. Usually the number of inodes in a filesystem is fixed (can be specified when crewting the FS). If you run out of indoes in a FS, then you cannot create files anymore
[12:58] <PCatinean> That's a bummer, not sure how to unstuck this
[12:58] <hggdh> PCatinean: this usually happen when you have (hundreds of) thousands of small files
[12:59] <PCatinean> it's docker related, it's a node in a cluster but docker is not even starting anymore because of the low space
[13:00] <hggdh> how to increase the number of inodes... depends on the filesystem. XFS, for example, allows to dynamically increase it, but ext4 does not
[13:01] <hggdh> one option is figure out WHERE you have these files; perhaps they are old docker logs, or something like it, and you can delete them
[13:02] <PCatinean> hggdh, it seems they are in aufs folder of /var/lib/docker but I cannot start clearing there since it can brek running containers
[13:02] <PCatinean> I used ncdu to get the data
[13:09] <hggdh> well... I have no experience with aufs, so... sorry. It seems aufs merges other filesystems (like overlayfs), but this is as far as I can go
[13:09] <PCatinean> sorry, I meant overlay2

[15:12] <stevenm> where (literally on the filesystem) does dpkg store knowledge of it's primary and foreign architectures?
[15:19] <dyeplexer> My system is freezing up at random times, which is I think due to my graphics driver in the system (for intel graphics). Opening any opengl application/hardware accelerated graphics progam in the system with the "iris" driver freezes it up immediately. I have been working around this using the environment variable `MESA_LOADER_DRIVER_OVERRIDE=i965` thus using the `i965` driver.
[15:20] <dyeplexer> Recently with newer versions of chrome and firefox it seems to be happening again maybe for the same reason. I get repeated messages of these: https://0x0.st/-ThN.txt in my kernel log. Can anyone tell me what is this for? Disabling hardware acceleration in chrome here seems to make the system more stable.
[15:20] <dyeplexer> And does anyone know how to solve the previous problem? I am running ubuntu 20.04.1 with linux 5.4.0-70-lowlatency

[15:34] <dyeplexer> although I think most of the problems arise from my update from 18.04 to 20.04. A lot of broken packages were there and who knows what cruft. Maybe I'll just try doing a fresh install

[18:13] <leftyfb> modifying /etc/resolv.conf directly is not recommended

[18:44] <[itchyjunk]> oh, hmm, no idea.
[18:44] <[itchyjunk]> Maybe running it has fixed it now
[19:01] <zmagii> Fuchs and leftyfb, thanks.
[19:58] <crackhead> Can anyone help me with this issue: I just installed/cloned a program, Xcalib, from the Git Repo, followed the cmake and make commands, for the installation, but now when I try to run the program, I get "no such file or directory", even though it seems the install finished fine..
[19:59] <crackhead>  I'm trying to install and use this Xcalib program to invert the monitor colors while doing a lot of editing and save my tired eyes..
[19:59] <crackhead> The Git channel guys say it's not a Git issue - it's a simple Ubuntu issue. So I hope someone here can help.
[20:01] <leftyfb> crackhead: undo/uninstall whatever you have done and run: sudo apt install xcalib # to install it. It's already in the Ubuntu repository
[20:02] <crackhead> I did, and that didn't work in the first place. Gave the ramp size error.
[20:02] <crackhead> So the suggestion in Askubuntu was to reinstall the Git version which was supposedly more updated than the repo file (which they said was from 2008)
[20:08] <EriC^> crackhead: maybe this might help https://forums.linuxmint.com/viewtopic.php?t=301627

[20:20] <vmguy23m> Hello, I have a USB tocuhscreen that isn't working. It fails to register the device upon connect, according to dmseg. However, it works fine on the lock screen. Any help?
[20:22] <vmguy23m> (i meant login screen, does nt work after logging out though)
[20:35] <kyle__> Is there a simple way to make less --raw behave as raw, instead of some stupid attempts to pipe to an external tool based on file extension?
[20:35] <kyle__> (honestly file extension?  What is this win95?)
[20:36] <vmguy23m> Please don't answer my question until I say I'm back, I have to go. I will be back at around 5 UK time
[20:37] <kyle__> vmguy23m: when you come back, pastebin the dmesg contents for what happens when you plug it in.  Would help.
[20:39] <kyle__> As for the less issue, take the case where you need a file NAMED .iso because a BMC will only boot a file named .iso, but is actually a fat formatted image.  less --raw boot.iso should let you see the fat headers & other raw info.  But instead it "cleverly" sees .iso, attempts to process as an iso9660 and gives you a helpful "CD-ROM is NOT in ISO 9660 format" message.
[20:43] <kyle__> less --raw is meant to be RAW output, for people who know they want raw output, and are using it to check very specific things.
[21:21] <Randolf> How can I set the timezone in Ubuntu 18.04 LTS to the Pacific Timezone?  This is for Vancouver, BC, Canada, but the command "timedatectl set-timezone Canada/Vancouver" says this is an invalid timezone.
[21:25] <cipherboy> Randolf: `ls /usr/share/zoneinfo` -- various entries there show the right invocations. I believe it is 'America/Vancouver' not 'Canada/Vancouver'
[21:33] <Randolf> Canada is not part of the USA, and this works on other systems.
[21:34] <Randolf> Can I just set Pacific Time?  Because if Washington, USA changes the way their timezone works, it won't be valid here for Vancouver, BC, Canada.
[21:35] <summonner> in /usr/share/zoneinfo/Canada there are 8 timezones
[21:36] <cipherboy> Randolf: On my 20.10 box, America/ includes other popular non-US destinations like Barbados and Buenos Aires and in this case, America generally refers to both North and South America. Could just be that on the other system they have a different zoneinfo version.
[21:36] <jeremy31> Randolf: It says America/Vancouver, not USA/Vancouver
[21:37] <jeremy31> CA	+4916-12307	America/Vancouver	Pacific - BC (most areas)
[21:38] <summonner> sudo timedatectl set-timezone Canada/Pacific
[21:38] <summonner> worked on mine just now.
[21:39] <summonner> Canada/Pacific is a symlink to ../America/Vancouver    so either try the above command again with sudo or use the symlink
[21:40] <jeremy31> The US Pacific time zone is US	+340308-1181434	America/Los_Angeles	Pacific
[21:49] <zamba> my ubuntu system is consuming nearly all of the allocated swap.. but the main memory is not exhausted.. how can i free up the swap space?
[21:50] <kxsl> kernel should manage it automatically. don't worry about freeing swap if there is free ram
[21:50] <jeremy31> zamba: how much RAM?
[21:51] <zamba> jeremy31: 8 GB
[21:52] <jeremy31> That is a bit odd unless you have a lot of browser tabs open
[21:54] <zamba> it's a headless server
[21:55] <zamba> but it's not healthy.. there are some issues with systemd pid 1 consuming a single core alone
[21:56] <lapidot> Running 18.04 and on boot I see a segfault in Xorg.0.log -- https://pastebin.com/QxmQHwxZ
[21:57] <sarnold> lapidot: my guess is this is related: [    26.173] (EE) Unknown chipset: NV167
[21:58] <sarnold> lapidot: maybe try the nvidia drivers instead of nouveau?
[22:07] <StupidDanbo> I can't run Chromium in Xubuntu 20.04.2. Running "chromium-browser" in a terminal gets me "cannot create temporary directory for the root file system: Permission denied"
[22:08] <StupidDanbo> only one search result for that error, in Japanese or something.
[22:08] <gnUser> Hi guys, my headphones microphone does not work on Ubuntu all of a sudden unless I press the inline volume button up or down. Any idea how to fix this?
[22:08] <Randolf> cipherboy/jeremy31:  Thanks, I'll use this for now then.  That should be called "Americas" rather than "America" because the USA is always referred to as "America" while North, Central, and South America are normally referred to as "the Americas."
[22:09] <jeremy31> Randolf: It seems everything in North America and South America is listed as America in time zones
[22:09] <Randolf> summonner:  Canada/Pacific just worked for me -- thanks!  (I must have mistyped this when I tried this earlier.)
[22:10] <sarnold> StupidDanbo: check dmesg or auditd logs
[22:10] <Randolf> jeremy31: Yeah, that seems to be the case.  That's unfortunate because it creates confusion since here in Canada we don't think of ourselves as Americans or as part of America.
[22:10] <retrospectacus>  my IntelliJ is installed by ubuntu "snap". How to upgrade to this tar.gz?
[22:11] <retrospectacus> https://youtrack.jetbrains.com/issue/IDEA-266391#focus=Comments-27-4835064.0-0
[22:12] <StupidDanbo> sarnold, I found dmesg but I don't know how to check auditd logs. I also don't know what I'm looking for.
[22:13] <sarnold> StupidDanbo: if you've got auditd installed,it'll be logging to /var/log/audit/audit.log
[22:13] <sarnold> StupidDanbo: look for DENIED messages from apparmor, that's part of the snap security policy enforcement
[22:15] <StupidDanbo> sarnold, like this? kernel: audit: type=1400 audit(1618387248.008:39): apparmor="DENIED" operation="capable" profile="/usr/sbin/cups-browsed" pid=1070 comm="cups-browsed" capability=23  capname="sys_nice"
[22:16] <StupidDanbo> or in syslog: kernel: [50643.353913] audit: type=1400 audit(1618437798.426:92): apparmor="DENIED" operation="mkdir" profile="/snap/snapd/11588/usr/lib/snapd/snap-confine" name="/home/tmp/snap.rootfs_M5wPet/" pid=11562 comm="snap-confine" requested_mask="c" denied_mask="c" fsuid=0 ouid=0
[22:17] <retrospectacus> nevermind, snap remove intellij-idea-ultimate
[22:17] <sarnold> StupidDanbo: yeah that second one -- strange.. maybe sudo snap refresh?
[22:20] <StupidDanbo> sarnold,  error: cannot perform the following tasks: - Run configure hook of "chromium" snap if present (run hook "configure": cannot create temporary directory for the root file system: Permission denied)
[22:21] <sarnold> StupidDanbo: yikes. uh. I'm thinking you'll need someone with more experience than me, try in #snappy ?
[22:57] <haijuno> Are there any other themes for gnome other than the ones included in the tweak app?

[23:28] <sneakyimp> so I downloaded the latest version of ubuntu to replace the default installed by apt (which has a bug). I have apt purged/autoremoved the old blender but I want the new blender to properly installed -- i.e., typing 'blender' in a terminal window will invoke the new blender. Can someone tell me a) which directory to put the blender.tar.xz contents in and b) tell me how the blender.desktop file, which doesn't specify any path to the app, 
[23:28] <sneakyimp> s supposed to find the app?
[23:29] <sneakyimp> in what directory does one put apps to make them available to all users (or at least root and my current user) ?
[23:29] <sneakyimp> ARG...i meant to say I downloaded the latest version of BLENDER. sorry sorry.
[23:33] <sarnold> sneakyimp: normally you'll put things you want available to everybody into /usr/local/bin/
[23:34] <sarnold> sneakyimp: that directory is usually in the PATH of whatever process would use the .desktop file to start blender, so it probably doesn't need the fully path
[23:44] <sneakyimp> sarnold: thanks+++! looks like /usr/local/bin does not exist on my Ubuntu 20.04 machine but this directory does in fact exist in my path.
[23:44] <sneakyimp> sarnold: there is, however, a /usr/bin directory full of apps
[23:45] <sneakyimp> sarnold: what is the difference between these two locations? I'd very much like to follow whatever appropriate traditions may apply.
[23:45] <sarnold> sneakyimp: yes, that's managed by dpkg or rpm or whatever distribution package system is in place
[23:45] <sarnold> sneakyimp: but /usr/local/ won't be touched by (nearly all) debs or rpms or whatever
[23:46] <sneakyimp> sarnold: if I create /usr/local/bin, does this directory need any special permissions?
[23:46] <Intelo> Does monitor have any relation with ubuntu?
[23:46] <Intelo> compatibility/support etc?
[23:46] <sarnold> sneakyimp: root:root 755
[23:47] <sneakyimp> sarnold: OK going to create that dir, give it a whirl
[23:51] <sneakyimp> sarnold: oh dang it looks like the blender.tar.xz file has a lot of contents (see https://paste.ubuntu.com/p/yjszC5njZc/ ). I don't think I should just move that stuff into /usr/local/bin. Should I create a directory /usr/local/bin/blender and put it in there? That doesn't seem like it'll work with the exec directive in the blender.desktop file, which says: Exec=blender %f
[23:53] <sarnold> sneakyimp: that readme.html probably describes what should go where
[23:55] <sneakyimp> sarnold: it says
[23:55] <sneakyimp> Linux: Unpack the archive, then run the Blender executable.
[23:55] <sneakyimp> sarnold: looks like some bad/vague advice here as well https://docs.blender.org/manual/en/latest/getting_started/installing/linux.html#install-from-blender-org
[23:56] <StupidDanbo> my /tmp folder was a symlink, and apparently "apparmor doesn't like symlinks" so I recreated the folder and I'm still getting the error that I don't have permission to create temporary directory for the root file system.
[23:57] <sneakyimp> stupiddanbo: only root (or sudo) has permission to make any directories in /
[23:58] <StupidDanbo> I don't know what I'm doing. I'm just trying to get Chromium to run, and snap and apparmor are in the way or something.
