[00:12] <henninb> hello, after installing lightdm on ubuntu 20.04 - when I try to login it returns to login screen, any advice?
[00:13] <guiverc> henninb, check you have free disk space, if insufficient free disk space in exists in $HOME (your user directory), login will fail causing you to logout
[00:14] <henninb> guiverc, 13% used on the root file system.
[00:15] <guiverc> space in $HOME is what matters, /home if partition seperately
[00:15] <henninb> guiverc, good point. my home is part of the root file system.
[00:18] <henninb> in the journalctl, i do see 'gkr-pam: unable to locate daemon control file'
[00:31] <henninb> ls
[01:02] <arooni> if i wanted to encrypt the /home/ partition on ubuntu 20.04 after its already installed is that possible
[01:02] <arooni> or would i need to reinstall
[01:04] <lapion> Grub adds the same root=UUID=xx for 2 installs on 2 different partitions
[01:10] <lapion> Okay I had to update-grub for the secondary partition
[01:11] <lapion> so first update the grub in the secondary partition then update the grub for the running system and then install the grub to the bootsector
[01:18] <Bashing-om> lapion: My experience dual booting 'buntus - you might consider disabling 30_os-prober ( /etc/grub.d/ ) in the secondary system to preclude recursion in grub's config file.
[01:20] <lapion> Bashing-om, the booted and the secondary where copies using dd and after the fact forgot to change the uuid in fstab so grub used the wrong uuid even though after the fact the uuid was changed on the ext4fs
[01:22] <Bashing-om> lapion: Still, you only want one system controlling booting per drive.
[01:31] <jayjo-> Is there a "recommended" way to run virtual machines on ubuntu today? In particular for running other linux machines (tails, kali, raspbian). I'm reading a lot about qemu. Do I need KVM to use it? Is this the right way to go?
[01:43] <lapion> Bashing-om, disabling that will only allow the secondary os to overwrite grub with a menu that cannot boot the primary
[01:54] <DouglasK> apt says I have "held broken packages", but when I run apt-mark showhold, I get no results... also dpkg -l | grep "^hi" gives nothing.  Ideas on how to fix things? This is Ubuntu 18.04
[01:56] <Bashing-om> DouglasK: Show us what you see, in a pastebin ' sudo apt update ; sudo apt upgrade ' - and we look for a PPA issue I bet :P
[01:57] <DouglasK> could well be ... one moment.
[02:01] <DouglasK> Bashing-om, https://pastebin.com/Jpwfhiwq
[02:03] <DouglasK> I included the requested, plus an apt-install that shows the error.
[02:03] <Bashing-om> DouglasK: Looking ^ .
[02:05] <Bashing-om> DouglasK: We can try - nut all bets are off - bionic install with "http://ru.archive.ubuntu.com/ubuntu xenial InRelease". Ouch !
[02:06] <DouglasK> Eh, it was set to ca.archive.ubuntu.com initially, but some recommended trying a different mirror.  Changing seemed to make no difference.
[02:07] <Bashing-om> DouglasK: What does the system think is the release ' lsb_release -a ' ?
[02:07] <Bashing-om> !info libssl1.0.0 bionic
[02:07] <DouglasK> It says Ubuntu 18.04.1 LTS
[02:08] <DouglasK> I can pastebin the full ver if you like.
[02:08] <DouglasK> It also says "No LSB modules are available".
[02:09] <Bashing-om> 1.0.2n-1ubuntu5.1doNaw let's see what we can do . For sure do not want to mix the releases between xenial and bionic.
[02:09] <DouglasK> So, put the sources.list over to bionic?
[02:14] <Bashing-om> DouglasK: Yeah - like ' sudo sed -i 's/xenialy/bionic/g' /etc/apt/sources.list . then see what the package manager thinks.
[02:14] <Bashing-om> Typo!
[02:15] <DouglasK> No worries... I've backed the file up and will do it in vim
[02:15] <Bashing-om> DouglasK: ' sudo sed -i 's/xenial/bionic/g' /etc/apt/sources.list '
[02:18] <DouglasK> Ok.  821 packages to upgrade.  wow.
[02:18] <DouglasK> Ya, this'll be a while.
[02:18] <DouglasK> also, "0 not upgraded" is promising.
[02:19] <DouglasK> I'll bbiab.
[02:19] <Bashing-om> DouglasK: Fingers crossed :D
[03:11] <TwoNotes> New 20.04 install sees one of my old disks (not the root disk)  with the wrong UUID so will not mount it.
[03:11] <TwoNotes> Instead it sees it as the original (now removed) old root disk
[03:13] <Bashing-om> TwoNotes: review /etc/fstab and compare to ' sudo blkid -c /dev/null -o list ' for the correct UUIDs .
[03:13] <TwoNotes> Isn't the UUID stored on the disk itself?
[03:14] <Bashing-om> TwoNotes: Kernel reads the /etc/fstab file to mount the partitions.
[03:15] <TwoNotes> I know that.  The question is how does it identify the disks.  /dev/disks/by-uuid ?
[03:16] <TwoNotes> Before fixing fstab, I am trying various mount commands
[03:18] <TwoNotes> If I physically replace the new boot drive with the old one, IT properly sees the second disk.  But the new boot disk does not.
[03:19] <TwoNotes> That blkid command sees this second disk as the original (now removed) boot disk.
[03:20] <TwoNotes> Perhaps if I disconnect the disk entirely and reboot, thinks will match up again
[03:21] <Bashing-om> TwoNotes: Humm ... ' sudo blkid -c /dev/null -o list ' <- The switch "-c /dev/null" ensures the command is not using any cached values and polls all of your hardware directly. The "-o list" switch is an option to order the output for easier reading.
[03:24] <DouglasK> Bashing-om, the system did finish the upgrade.  Now to see if it reboots.
[03:24] <TwoNotes> The blkid command sees the UUID of this phantom disk to be the same as my old boot disk drive, which is physically removed and sitting on my deks here
[03:25] <TwoNotes> *desk
[03:26] <Bashing-om> TwoNotes: Got me - cached data ? where the -c option polls the hardware, does this show correctly  ?
[03:30] <TwoNotes> Even with -c it is showing obsolete information about the disk.
[03:30] <Bashing-om> TwoNotes: That then is above my skill level.
[03:31] <TwoNotes> Perhaps shutting down, disconnect the disk, then reboot, will force the BIOS to update its idea of what is there
[03:31] <TwoNotes> Thanks anyway for the fancy blkid command.  That is useful
[03:32] <Douglas_K> Bashing-om, a) it rebooted fine, and b) libssl-dev installed without issue.  Thank you!  Now I can go compile a current version of znc and get back on IRC with style.
[03:35] <Bashing-om> Douglas_K: \o/ - Good things can happen :P
[03:37] <Douglas_K> Absolutely!  I work 3rd lvl support, I'm decent with Ubuntu, but it's not my forte.  I truly appreciate the assist.
[04:38] <Norkle> vote trump!

[09:25] <omega_doom> hello. I am trying to resolve a problem how to enable a hotspot with vpn.
[09:26] <narakrish> Hello all, I'm currently working on a EPOS application developed using Qt running Ubuntu 16.04. We are using CUPS service for printing. CUPS version is 2.1.3. The system is running with a 2GB RAM. We are observing the CUPS memory keeps on increasing and at some point the printers does not print. We are using default CUPS configuration. We are
[09:26] <narakrish> having around 7 network printers connected on the network. Any idea why the memory is rapidly increasing ?
[09:27] <omega_doom> without vpn hotspot works just fine but with vpn it disconnects right away. Does anyone know what might be wrong?
[09:53] <xzu> Hello. new here. I need to make a bug report, but I don't know where the problem really comes from
[09:55] <xzu> (sorry accidental return) I suspect samba. https://askubuntu.com/questions/1272185/20-04-cant-find-brotherdcp-network-printer-when-16-04-does-dcp-j752dw and also https://askubuntu.com/questions/1256728/ubuntu-20-04-windows-printer-via-samba-browse-click-no-response?noredirect=1#comment2160922_1256728
[09:56] <xzu> So the question is: what should I use for ubuntu-bug: samba? cups? system-config-printer?

[10:18] <b247_eu> dear users, i have a strange problem with ipsec, it creates a table 220 route that prevents me to acces my local subnet, if one with same problem (or alike) please advice
[10:37] <wyoung> Hi, what is with iptables version 1.8? Why can't I type in --dport any more?

[10:50] <jlj> Hi! I have a ufw/firewall question. (Let me know if I should be asking elsewhere.) I've been able to successful bridge some LXD containers to my Ubuntu host's ethernet device, but only with ufw disabled. I had been thinking that I could just added some interface rules to the before... files to get it working with ufw enabled, but my reading has turned up some folks working with ebtables to ensure bridged
[10:50] <jlj> traffic is properly processed by the host firewall. I hadn't even heard of ebtables as of Monday; before I dive in, am I making this too complicated? I can put some of the ufw blocks in the Ubuntu pastebin, if that helps.
[11:47] <zetheroo> from time to time I receive a USB hard disk which I cannot mount in Ubuntu (I am using 18.04) and I cannot figure out why. The disk is seen by fdisk https://paste.ubuntu.com/p/M6vXHcwxWC/
[11:48] <zetheroo> it shows up in Nautilus and the right-click menu shows the Mount option, but clicking on it does nothing
[12:35] <BluesKaj> Hi all
[12:40] <malpkt> my device is ubuntu certified (https://certification.ubuntu.com/hardware/201812-26716) and it seems like its codename is somerville (canonical-oem-somerville-bionic-amd64-20180608-47+bolt-l+X51) and i need to obtain the driver for the fingerprint sensor. i found http://dell.archive.canonical.com/ but i dont know what repo to use
[12:41] <malpkt> https://gitlab.freedesktop.org/libfprint/libfprint/-/issues/183 someone already managed to extract it but its not public anymore :(
[14:12] <rob_jones> How can i make a new file created adopt the file system perms of its parent and not my user
[14:12] <rob_jones> I want chmod and chown to match that of its parent
[14:16] <jonfen> i use scp, but i have a situation where i am already ssh'd into the remote, and i want to copy a file from local to the remote.  how can i do that?
[14:17] <rob_jones> cant you use filezilla?
[14:17] <rob_jones> sftp
[14:19] <jonfen> scp would be the one i would use, but since i am already ssh'd, i was wondering if there was something else.  i don't have ftp or sftp configured on either box
[14:20] <jonfen> rob_jones: https://askubuntu.com/questions/642236/how-to-make-the-newly-created-files-inherit-the-directorys-permissions
[14:20] <rob_jones> thanking you :)
[14:29] <b247_eu> it will it work if I just create (from a template) the "/etc/wpa_supplicant/wpa_supplicant.conf" file (on #ubuntu 20.04) and enable from here p2p support bits?

[14:44] <Gh0sta> What is the best way to mount iPhone storage on Ubuntu?
[14:48] <oerheks> Gh0sta, see this howto; https://www.maketecheasier.com/easily-mount-your-iphone-as-an-external-drive-in-ubuntu/
[14:48] <Gh0sta> would I be able to copy photos as well?
[14:48] <Gh0sta> oerheks: thanks
[14:58] <Gh0sta> oerheks: thanks, that did the trick
[14:59] <oerheks> Gh0sta, have fun!
[15:07] <bnason> Is there any way to get the ubuntu server installer to use the cloud config file automatically from a floppy/cd? I'm trying to use Packer to automate creating my vm templates in vsphere and the only way I've gotten it to work (and every example online shows) it using boot_commands and hosting a http server for the cloud-init. The http server is problematic since my vcenter server isn't able to communicate with my local machine.
[15:08] <bnason> So I've had to create a script to automate creating a ssh reverse proxy to a server it can communicate with.
[15:16] <lotuspsychje> bnason: try the #ubuntu-server channel for likeminded volunteers if you want
[15:17] <lotuspsychje> malpkt: i hear gnome 3.38 will get better fingerprint support
[15:22] <bnason> thanks
[15:28] <malpkt> lotuspsychje: i dont think it has anything to do with gnome
[15:28] <malpkt> gnome wont help me without the proprietary driver
[15:29] <lotuspsychje> malpkt: anything to see in your dmesg?
[15:30] <malpkt> no. i just need the proprietary driver because fprintd doesnt have one by default
[15:30] <malpkt> it may be in one of the repos but i dont know how to properly inspect a repo
[15:31] <malpkt> i also obtained an ubuntu image which may include the driver but i dont know where it would be
[15:31] <oerheks> malpkt, what driver? the list on https://launchpad.net/~fingerprint/+archive/ubuntu/fprint and https://fprint.freedesktop.org/supported-devices.html  is all that is supported
[15:31] <malpkt> https://gitlab.freedesktop.org/libfprint/libfprint/-/issues/183
[15:31] <malpkt> my device is https://certification.ubuntu.com/hardware/201812-26716 so there will be a driver in the repos or in an ubuntu image
[15:33] <oerheks> 27c6:530c is not in the list.
[15:33] <malpkt> yes, its not supported by default, so i must obtain a driver for it manually
[15:33] <malpkt> i already have an ubuntu image and found out things like my laptops codename, some repos etc
[15:34] <oerheks> good luck with your search, there is no driver on our iso's.
[15:35] <malpkt> this is a dell ubuntu image
[15:35] <lotuspsychje> malpkt: there's also an interesting bug #1721909
[15:36] <malpkt> Bus 001 Device 002: ID 27c6:530c Shenzhen Goodix Technology Co.,Ltd. Fingerprint Reader
[15:36] <malpkt> it gets recognized
[15:38] <oerheks> even this post fails https://www.reddit.com/r/Dell/comments/hq3kf3/xps_13_fingerprint_drivers_are_here/
[15:41] <malpkt> i couldnt obtain an image for my latitude 3500 but for a G3 3590 which has the same fingerprint reader
[15:41] <malpkt> it contains these files: https://0x0.st/iI6U.txt
[15:42] <malpkt> so if it doesnt contain anything useful, there has to be something in the repo i mentioned, right?
[16:40] <AlexPortable> The bottom portion of my screen is broken. How would I 'exclude' this area from the OS trying to show something there?
[16:41] <oerheks> AlexPortable, no way to do that, AFAIK
[16:41] <lotuspsychje> maybe some kiosk software?
[16:41] <lotuspsychje> that could lock things into a window
[16:45] <AlexPortable> and then run every program in that window?
[16:45] <elias_a> Which log does Ubuntu use for logging installed packages?
[16:46] <cucumber> hi there everyone
[16:46] <lotuspsychje> AlexPortable: well kiosk mode is actually designed to browse in, but you could try tweaking things perhaps
[16:47] <lotuspsychje> elias_a: /var/log/dpkg
[16:47] <cucumber> I just had the chance and the privilege to check the new focal distro
[16:47] <cucumber> I have a question if anyone is willing to help me with
[16:47] <lotuspsychje> shoot cucumber
[16:48] <cucumber> thank you lotuspsychje  how was the name "focal" chosen? and what does the eyes being brightened and having lines on them mean?
[16:48] <lotuspsychje> !codenames | cucumber
[16:48] <cucumber> Have the backdoors been improved? more monitoring or something?
[16:49] <cucumber> the eyes give me the creeps
[16:49] <elias_a> lotuspsychje: TY
[16:49] <lotuspsychje> cucumber: lets focus on ubuntu support channels in here please
[16:50] <cucumber> oh ok
[16:50] <cucumber> thanks
[16:50] <lotuspsychje> cucumber: feel free to use the #ubuntu-discuss channel for other ubuntu talk
[16:50] <cucumber> I certainly will
[16:50] <cucumber> thank you lotuspsychje
[16:51] <lotuspsychje> AlexPortable: a virtual machine could also be an idea, giving you a window sized
[16:55] <rfm> AlexPortabe, lotuspsychje xnest would be less overhead than a VM but setting up the session would take a bit of work
[16:55] <lotuspsychje> rfm: i'm not familliar of that, what does it do?
[16:56] <oerheks> does that help a broken screen?
[16:57] <malpkt> i wonder if xrandr's --transform could help
[16:57] <lotuspsychje> might not oerheks :p
[16:57] <rfm> lotuspsychje, it's an X server that renders into a X window.  so start Xnest, resize its window to the working part of the screen, run everything there
[16:57] <malpkt> like this: https://superuser.com/questions/1435053/how-to-use-xrandr-to-crop-part-of-monitor-off
[16:58] <lotuspsychje> rfm: interesting!
[17:00] <rfm> apparently there's something called xephyr which is also a nested X server.  know nothing of it (Xnest is very old, we used to use it back in the '90s to test new window toolkits without breaking the working session)'
[17:13] <malpkt> do you think dell would make an ubuntu image available for my machine (https://certification.ubuntu.com/hardware/201812-26716)? it came with windows 10. i still have warranty
[17:13] <samthewildone> what is the way to rsync multiple (source) directories to multiple (destination) directories ?
[17:13] <samthewildone> I'm doing "# rsync -avz dir1/ dir2/ dir3/ ... user@server:/dir1" <- how to do create multiple destinations ?
[17:15] <oerheks> samthewildone, you are anwered in ##linux
[17:15] <oerheks> malpkt, ask dell?
[17:15] <oerheks> i have no confirmation your fingerprint will work.
[17:16] <malpkt> https://gitlab.freedesktop.org/libfprint/libfprint/-/issues/183 - seems like there is a way
[17:17] <ioria> malpkt, already tried this ? http://dell.archive.canonical.com/updates/pool/public/libf/libfprint-2-tod1-goodix/
[17:18] <malpkt> no, i will take a look
[17:20] <oerheks> ioria, good spot!
[17:20] <oerheks> why did i not find this..
[17:20] <malpkt> this looks very promising. it contains the correct usb id
[17:20] <lotuspsychje> the famous dell repos
[17:21] <malpkt> i will make sure to document it if it works
[17:21] <malpkt> i wont be DenverCoder9
[17:41] <swensson> So, I've recently started to use screen, I did loose the connection and the screen -r does not work & prompts this: 1264.pts-0.myhostnamehere   (09/16/2020 03:48:19 PM)        (Attached) How can I jump into that screen? .O
[17:42] <leftyfb> swensson: screen -D -r
[17:42] <jozefk> I got KUbuntu 20.04 and sometimes, often, when I turn on the PC and try to play a video or audio file, the sound is stuttering. Is there a fix for that? It's driving me crazy to keep reabooting always. And now, even after reboot it's still there the same issue
[17:43] <swensson> ah, cheers leftyfb ! =)
[17:47] <lotuspsychje> jozefk: wich video player are you using? is your sound and graphics driver loaded correctly?
[17:50] <swensson> how about two screens open?  1735.pts-1.myHostnamehere and  1264.pts-1.myHostnamehere
[17:51] <jozefk> lotuspsychje: I tried both VLC and MPV. I rather like to use MPV. Graphics must be loaded correctly. About sound drivers I don't know. How do I check that?
[17:51] <lotuspsychje> jozefk: sudo lshw -C sound
[17:52] <lotuspsychje> jozefk: some cases on nvidia drivers, sound can get affected too, might doublecheck too
[17:53] <jozefk> lotuspsychje: https://paste.ubuntu.com/p/dMdKrRgMC6/
[17:54] <lotuspsychje> jozefk: ok seems loaded, what about your nvidia driver version? nvidia-smi
[17:54] <jozefk> https://paste.ubuntu.com/p/832n6v9Xxp/
[17:54] <lotuspsychje> jozefk: ok tnx, could you try a switch to 435 as a test please?
[17:55] <jozefk> 450 was installed automatically by CUDA
[17:55] <jozefk> How do I switch to 435?
[17:57] <lotuspsychje> jozefk: lets see wich drivers are available for your card, ubuntu-drivers list
[17:57] <jozefk> https://paste.ubuntu.com/p/DRSB6X4nDG/
[17:58] <lotuspsychje> jozefk: ok, so 435 is among them, you can try the switch
[17:59] <jozefk> is that done through cli or ?
[17:59] <lotuspsychje> jozefk: you can choose, havent used kubuntu in a while, so not sure where they handle drivers GUI there
[18:00] <lotuspsychje> jozefk: from apt, sudo apt install nvidia-driver-435 and reboot
[18:00] <jozefk> ok. I will try and see what happens
[18:00] <jozefk> cli is usually more simple to me
[18:01] <lotuspsychje> jozefk: if it doesnt influence, we can try other steps
[18:01] <jozefk> that thing didn't work though: https://paste.ubuntu.com/p/HvR7npGgqQ/
[18:02] <lotuspsychje> jozefk: do you have external ppa's added to your system?
[18:03] <jozefk> maybe if they got installed automatically somehow, like for Chrome, or Visual Studio Code. I don't know
[18:03] <jozefk> It could be that some where added when installing CUDA
[18:03] <jozefk> too
[18:04] <lotuspsychje> jozefk: unmet dependencys often arise when external ppa's fight with apt sources
[18:05] <jozefk> https://paste.ubuntu.com/p/rpBvkV9swc/
[18:07] <lotuspsychje> jozefk: i think the ubuntu drivers get mixed with your cuda repo
[18:07] <lotuspsychje> jozefk: we can only advice to get your system as vanilla possible here, clean the external repos and fix your sound issue first
[18:08] <jozefk> then later I will have another issue, to install cuda and get it working :) but maybe I can't have both, who knows :)
[18:08] <malpkt> ioria: it worked. thank you so much
[18:08] <lotuspsychje> jozefk: could you pastebin your dmesg plz?
[18:09] <lotuspsychje> malpkt: tnx for the feedback, interesting for us to know ioria oerheks
[18:09] <ioria> malpkt, good job
[18:10] <jozefk> https://paste.ubuntu.com/p/sdxSQmDFJw/
[18:11] <malpkt> ioria: i also found a PKGBUILD which automates this: libfprint-2-tod1-xps9300-bin
[18:12] <jozefk> by the way I use the sound from MoBo, not from GPU. anyway, maybe there is some conflict between them
[18:15] <lotuspsychje> jozefk: there seem to be some errors about sound indeed, nd_hda_intel 0000:0a:00.4: No response from codec, disabling MSI: last cmd=0x0043a03e
[18:16] <jozefk> that's something to do with the sound on MoBo. Maybe GPU drivers aren't affecting that? or what could be the cause?
[18:17] <lotuspsychje> jozefk: i would still try the driver switch, ive seen more users in the past with those fixed by driver switch
[18:19] <jozefk> in that case I must forget about cuda I think. coz it's not going to work if I have nvidia drivers installed first and I try to install cuda
[18:20] <ax562> is there a way to check what version of intel firmware is loaded?
[18:30] <jozefk> https://bugzilla.kernel.org/show_bug.cgi?id=205229
[18:31] <jozefk> that seems related to my problem. if that error from dmesg is a right track. I don't have Intel CPU though
[18:45] <tomreyn> jozefk: before you try anything else, fix the vmware network driver problem.
[18:45] <tomreyn> (i didn't follow your chat, just looked at your dmesg)
[18:47] <jozefk> tomreyn: could that affect the sound issue?
[18:49] <tomreyn> jozefk: it taints the kernel, and it triggers an oops, could affect the kernel in many ways. this doesn't have to affect sound, but can.
[18:49] <tomreyn> alternatively just don't load those modules tainting the kernel and see whether you can still reproduce the audio problem
[18:50] <jozefk> is that done by modifying the grub or how do I do it?
[19:03] <bumblefuzz> how do I disable ipv6 on ubuntu system-wide?
[19:04] <daoumilseitek> hi
[19:04] <daoumilseitek> i have to install an ubuntu 16.04 for work
[19:04] <daoumilseitek> towards the end of install it seems ubiquity is removing every single package, one by one
[19:05] <daoumilseitek> (and i don't even know where from − install or live)
[19:05] <daoumilseitek> looks like a bug
[19:05] <daoumilseitek> anyone run into similar bug
[19:05] <daoumilseitek> it takes very long
[19:06] <daoumilseitek> it's a virtualbox install (for now) of 16.04.7 desktop
[19:14] <ToTheInternet> hello. i set up ubuntu with a GUI on AWS EC2 following the official documentation: https://ubuntu.com/tutorials/ubuntu-desktop-aws#2-setting-up-tightvnc-on-aws I can connect to the instance but the resolution is tiny, and all the documentation about changing it talks about the "Activities" overview but i don't have that? how can i bring it up?
[19:14] <ToTheInternet> obv i don't usually use ubuntu so pls excuse the basic question. pressing my Windows key ("Super key") doesnt do anything
[19:14] <tomreyn> !blacklist | jozefk
[19:15] <osse> ToTheInternet: do you see button in the lower left with 3 by 3 squares?
[19:15] <tomreyn> alternatively add    modprobe.blacklist=MODULENAME   to the kernel command line
[19:15] <bumblefuzz> so, I've disabled ipv6 using /etc/sysctl.conf but 'ip -6 addr' still shows an ipv6 address... why??
[19:16] <ToTheInternet> osse: no. there is a button with a tool tip saying "Click here to hide all windows and show the desktop"
[19:16] <ToTheInternet> the button does exactly that
[19:16] <jozefk> tomreyn: I see I can blacklist modules with kmon too https://github.com/orhun/kmon#blacklisting-a-module
[19:17] <jozefk> just not sure how do I unblacklist them later :)
[19:17] <jozefk> Or maybe I should better fix the vmware network card driver issue instead
[19:20] <bumblefuzz> can someone explain how 'cat /proc/sys/net/ipv6/conf/all/disable_ipv6' outputs 1
[19:20] <bumblefuzz> and how 'ip -6 addr' outputs an ipv6 address?
[19:21] <ToTheInternet> osse: this is what the desktop looks like https://ibb.co/tbz1dB7
[19:21] <techied> hey, I'm trying to enable livepatch on my server. I did `sudo snap install canonical-livepatch` which appears to have worked correctly (canonical-livepatch 9.5.5 from Canonical✓ installed) but when I run `sudo canonical-livepatch enable 820---` it just hangs until i ctrl+c
[19:22] <osse> ToTheInternet: very interesting. that looks like an older ubuntu
[19:22] <ToTheInternet> i think it's gnome maybe
[19:22] <ToTheInternet> i mean i did do:  sudo apt install ubuntu-desktop
[19:23] <oerheks> techied, what is the use for `sudo canonical-livepatch enable 820---`???
[19:23] <techied> what do you mean?
[19:23] <oerheks> installing the snap makes it start automaticly
[19:23] <techied> no, you need to enable it with the livepatch token according to https://auth.livepatch.canonical.com and https://ubuntu.com/security/livepatch
[19:23] <ToTheInternet> maybe i'm missing some packages that i need to install to get the "normal" ubuntu gui?
[19:24] <techied> i did it on another system (my laptop) and it worked fine with this method
[19:26] <oerheks> wait,  820--- is your token?
[19:26] <techied> well i redacted the rest
[19:26] <techied> it starts with 820
[19:26] <oerheks> i see, i wondered about that number
[19:27] <techied> finally got a message back: `2020/09/16 21:26:20 error executing enable: cannot enable machine: bad temporary server status 500 (URL: https://livepatch.canonical.com/api/machine-tokens) server response: machine token already exists`
[19:29] <jozefk> I think I will try to install new VMWare Player version and see what happens
[19:29] <oerheks> check your ubuntu one account, i guess, to see if you can enable your server, maybe there are 3 attempts already?
[19:29] <bumblefuzz> does anyone know how I'm still getting an ipv6 address in ubuntu when I've "disabled" ipv6 via sysctl.conf?
[19:31] <oerheks> isn't sysctl the old way? you can disable ipv6 in your networkmanager easily.
[19:31] <jozefk> will be back after reboot and test
[19:32] <oerheks> sae would be in grub; GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1"
[19:32] <techied> oerheks: thanks, turned out to be the machine's  UUID; https://askubuntu.com/questions/1264961/
[19:33] <bumblefuzz> sorry this is ubuntu server
[19:33] <bumblefuzz> I don't have a desktop
[19:37] <jozefk> after installing the new version of VMWare Player, and reboot, sound is back. I'm not sure now if that fixed the problem or it's just working randomly :)
[19:38] <jozefk> maybe the dmesg can tell?

[19:39] <TR2990WX> hi, right after the installation on my laptop I see a nice logo when the laptop startup. Then I installed a newer mainline kernel and the logo disappeared and the boot process show a few warnings/errors. Is there a way to bring back the nice logo ?
[19:41] <ToTheInternet> is there any way how i can bring up the thing that the Action key brings up? without using the Action key?
[19:41] <ToTheInternet> because its not working. i installed the ubuntu-desktop package on a fresh ubuntu 18 install
[19:42] <ToTheInternet> and pressing the windows key doesn't do anything.
[19:44] <daoumilseitek> FTR my bad ; it appears to be a normal part of install
[19:46] <ikonia> doesn't a fresh ubuntu 18 install come wuth ubuntu-desktop already installed ?
[19:49] <oerheks> ikonia, yes?
[19:49] <ikonia> so why would ToTheInternet need to install ubuntu-desktop package on a clean ubuntu '18' install
[19:49] <oerheks> bumhow did you control networking on your server? not worthy to mention in your 1st question?
[19:50] <oerheks> oh
[19:50] <oerheks> ikonia, no idea, some want to make it a trivia channel
[20:24] <shurdeek> I'm wondering what software is used to generate the images at https://cloud-images.ubuntu.com/ . I need to use a modified image, as I want to use NFS root and the published images don't have the kernel module for my network card (RTL8111). I thought it uses vmbuilder but that's obsolete.
[20:45] <oerheks> shurdeek, all you need is the backport-iwlwifi-dkms package
[20:45] <oerheks> !info backport-iwlwifi-dkms
[20:46] <oerheks> for normal iso's one could use cubic, why would a cloud image need this wireless package?
[20:50] <jeremy31> The RTL8111 should be supported by the r8169 kernel module in the Ubuntu kernels
[20:51] <shurdeek> thank you for the information, however, that doesn't really solve my problem
[20:51] <shurdeek> I boot the cloud images over PXE.
[20:52] <shurdeek> I could probably manually modify the image to add the module, but I want a clean solution rather than a hack.
[20:52] <oerheks> so, why can't you add that driver to the image?
[20:53] <shurdeek> I probably could, but I want a proper way to do that, instead of doing it manually.
[20:54] <shurdeek> I could mount the image, add the module, regenrate initramfs and save everything. But there has to be a more normal way to do this.
[20:54] <jeremy31> The r8169 driver is part of linux-modules-extra, so that must not be part of the image
[20:55] <shurdeek> do you know if there is a more standardised approach than modifying the image manually? I can't find any documentation on how these images are created in the first place
[20:55] <shurdeek> they used to be created by vmbuilder, but that's now obsolete and I haven't found any info on what replaced it
[20:57] <shurdeek> hmm maybe if I used a different prebuilt kernel....
[21:06] <arktvrvs> boon2
[21:23] <abyssangel> hello
[21:52] <rr123> was increasing confused by ubuntu dns, in NetworkManager I set manual DNS to a invalid address, turn interface off/on to make it take effect, systemd-resolve --status showed this DNS's IP(though unreachable), however I can still surf, nslookup reports it gets from 127.0.0.53, what the hack is that, and where does it got IP from?
[21:54] <rr123> is i do: nslookup invalidwhatever.com, it says ""server cn't find invalidwhatever.com: NXDOMAIN", so it seems there is a local cache for all hostnames I have tried
[21:54] <rr123> sudo systemd-resolve --flush-caches does not help either
[21:55] <rr123> systemd already made linux bad enough, ubuntu's netowrk changes made it even more difficult
[21:56] <leftyfb> rr123: use nm-connection-editor
[21:56] <xtao> 127.0.0.53 is systemd-resolved , and i believe it has a hardcoded fallback in the case of no DNS servers working where it goes to 1.1.1.1, 9.9.9.9, and 8.8.8.8
[21:56] <leftyfb> and under "Method" pick "Automatic(DHCP) addresses only"
[21:57] <rr123> xtao: i hate that hard-code thing, because of it i could not debug pihole
[21:57] <leftyfb> xtao: that is incorrect. 127.0.0.53 is pointing to localhost which runs a DNS caching daemon and then goes out to your configured DNS. There is no valid default namesever
[21:58] <leftyfb> rr123: setting a manual DNS entry in the NM for the latest Ubuntu versions doesn't do anything unless you also set the entire profile to manual
[21:59] <rr123> i mean, let me just change /etc/resolv.conf and be done with it if I need override whatever is hidden, systemd/ubuntu wasted me half of day debugging while in the old days, it should take less then 5 seconds
[21:59] <rr123> leftyfb: how to set the entire profile to manual
[22:00] <leftyfb> rr123: https://linuxconfig.org/how-to-configure-static-ip-address-on-ubuntu-18-10-cosmic-cuttlefish-linux
[22:00] <rr123> all I want is to just manually designate a DNS, for god sake
[22:00] <leftyfb> rr123: I've given you 2 options
[22:01] <rr123> sometimes i feel ubuntu is getting worse than windows, unnecessarily complex
[22:01] <leftyfb> rr123: this is a support channel. Please following along with troubleshooting. Keep all rants in #ubuntu-offtopic
[22:02] <leftyfb> rr123: and to clarify, the issues you're experiencing are with the Gnome project, not Ubuntu.
[22:02] <rr123> leftyfb: in the half day I already tried those, does not work for me
[22:02] <xtao> well it's not incorrect is it. a process called systemd-resolved is listening on 127.0.0.53:53 as a stub resolver. you can see that with sudo fuser 53/udp and then sudo ls -l /proc/<pid>exe
[22:02] <leftyfb> xtao: yes, that is a caching daemon
[22:03] <rr123> will systemd-resolve --flush-cache clean that caching daemon?
[22:04] <leftyfb> rr123: it doesn't cache which nameserver you have configured. It caches DNS queries
[22:05] <rr123> nslookup google.com output first line is always 127.0.0.53, never saw anything with DNS server
[22:05] <rr123> so it always goes to local cache first
[22:06] <leftyfb> yes
[22:06] <rr123> which means my tcpdump port 53 can not catch anything?
[22:06] <rr123> but i can see tcpdump port 53 on the gateway
[22:09] <rr123> so I tried to change /etc/resolv.conf to 28.0.0.53 which is invalid, nslookup still happily reports right IP address, some hidden code somewhere still
[22:10] <rr123> actually whatever is in /etc/resolv.conf does not matter, on the gateway tcpdump reports 28.0.0.53 is responding with DNS replies
[22:12] <rr123> i delete /etc/resolv.conf that does stop nslookup
[22:12] <rr123> the problem with systemd is that, if there is an issue, nobody knows how to debug and fix
[22:54] <sine0> how do you get the version number of a software in apt-chace
[22:54] <sine0> cache even
[22:57] <hggdh> sine0: apt-cache policy
[22:59] <Bashing-om> sine0: ?? 'apt-cache show <package>' shows the version. "apt-cache show mousepad >> Version: 0.4.2-1". Maybe I do not understand your intent ?
[23:03] <sine0> show worked, thanks
[23:03] <Bashing-om> sine0: \o/
