[00:10] <sarink> ssh user@host "node -v"  gives me "node: command not found". i think this is because the $PATH is different? i added "PermitUserEnvironment yes" to /etc/ssh/sshd_config, but it still doesn't work. what else am i missing?
[00:11] <leftyfb> sarink: try ssh user@host "source .bashrc ; node -v"
[00:12] <leftyfb> sarink: you could also just give the full path to node
[00:14] <sarink> yeah if i use the full path it works. but i'm writing a much longer script and don't want to have to do that for everything... sourceing also doesn't work
[00:15] <leftyfb> sarink: maybe something like ansible would be better than a "longer script"?
[00:16] <sarink> i don't see why i can't get the same PATH from the selected user's profile? surely there is a way to do such a thing?
[00:18] <leftyfb> sarink: depends on where that PATH is set
[00:23] <matsaman> sarink: always a way
[00:35] <neighbourmike> im attempting to re-image my ubuntu desktop due to a problem with peer connectivity, this should reset smb, network settings, the works correct?
[00:36] <leftyfb> neighbourmike: re-image?
[00:36] <neighbourmike> smb.conf*, d.init or ifconfig
[00:37] <leftyfb> neighbourmike: what do you mean by "re-image"?
[00:37] <neighbourmike> leftyfb: i think i mean like re-set sorry for not being clear.
[00:37] <leftyfb> neighbourmike: there is no reset capabilities built into ubuntu by default
[00:39] <leftyfb> neighbourmike: you should either troubleshoot the individual issues and fix them 1 at a time or reinstall ubuntu from scratch and restore your files from backup
[00:40] <neighbourmike> yeah i know that. I had wsdd, and samba properly configured for my LAN filesharing drive to all other PCs, including win10 which gave me problems at first..So i was thinking if i could save my settings for samba and wsdd but reset my dhcp ip etc network related info it would solve my peers not connecting.
[00:40] <neighbourmike> on qBittorrent
[00:42] <neighbourmike> like literally i have 0 peers, 0 bits but my download is fine, so ive disabled firewall, as well as port forwarding TCP UDP port but nothing seems to allow peers in Qbittorrent
[00:42] <neighbourmike> set up port forwarding*
[00:43] <leftyfb> neighbourmike: I don't think torrent "peer connectivity" has anything to do with your samba settings. You'd be on your own with wsdd as it doesn't look like that's an officially supported package in ubuntu
[00:43] <sarnold> neighbourmike: are you behind a NAT firewall?
[00:45] <neighbourmike> i dont think so
[00:45] <leftyfb> neighbourmike: if you're doing port forwarding on a router, you're more than likely NAT'd
[00:45] <neighbourmike> it's just strange it's at zero bits. None. Before I had some connectivity. Now I've got none.
[00:45] <neighbourmike> connections*
[00:46] <neighbourmike> Should i try to simplify what could be causing the problem by disabling port forwarding and resetting my ubuntu desktop network settings from static ip to local dhcp
[00:47] <neighbourmike> last time i tried unfortunately setting eth0 back to defaults nothing seemed to do change.
[00:47] <neighbourmike> i have my modem firewall in localhost set to minimum

[05:17] <mr_lou> Hello all.
[05:17] <mr_lou> For a long time now I've noticed weird audio issues. Playback of Twitch streams or mp3 files from VLC often gives a variation in pitch, as if it's playing from a bendt vinyl record or something. Makes absolutely no sense to me whatsoever. Anyone heard of this before?

[06:03] <Guest96> zaggynl: No output for "ss | grep 70 "

[06:12] <ihristov> Try wth ss -tapn and get the PID
[06:15] <Guest96> ss -tapn does not show PID.. It displays "State      Recv-Q Send-Q                                                          Local Address:Port                                                                         Peer Address:Port"

[09:18] <webchat68> Hi
[09:18] <webchat68> Is it possible to create an iso from my current ubuntu installation
[09:19] <lotuspsychje> webchat68: you want a backup from your installed system/packages?
[09:20] <webchat68> Transientively, yes  -  I'm moreso looking to have an iso that's preconfigured how I like it for distribution amongst servers
[09:21] <webchat68> IE; instead of reinstalling packages, repositories, rebuilding binaries etc... I will install this iso and have those base packages installed.
[09:21] <lotuspsychje> webchat68: unofficialy there is cubic to create ubuntu iso's yourself, but for server mass deploy you might better talk to the #ubuntu-server guys
[09:22] <webchat68> thanks lotus

[12:56] <mtj> hey folks, is the snapd package required for a basic gnome desktop install?
[12:56] <mtj> ..and the various core18, gnome-3*, gtk-common-themes snap pkgs?
[12:57] <oerheks> yes.
[13:43] <mtj> oerheks: thanks for confirming.. curious, what breaks snapd (and its pkgs)  are removed?
[13:44] <mtj> s/snapd/if snapd/
[13:47] <lotuspsychje> mtj: you can purge snapd and keep running ubuntu/gnome if thats your question?
[13:47] <mtj> lotuspsychje: yep, thats my situation
[13:48] <mtj> just reading this... https://www.kevin-custer.com/blog/disabling-snaps-in-ubuntu-20-04/
[13:50] <mtj> im guessing that the  core18, gnome-3*, gtk-common-themes snap pkgs are required deps general snap apps
[13:51] <mtj> many thanks

[14:32] <ens> i'm interested in learing about cloud computing + learning more python with ubuntu projects. is there an open source project / community that i can get involved with that deals with that a lot so i can skill up?
[14:32] <ens> learning*
[14:32] <rbasak> cloud-init perhaps?
[14:35] <tzpl> hi. how can i upgrade from 20.10 to 21.04?  do-release-upgrade says 'Your Ubuntu release is not supported anymore'
[14:35] <ens> rbasak: thanks, just been checking out the wiki for it. looks pretty cool.
[14:38] <Helenah> Hiya, my /var/lib/dpkg/alternatives/x-www-browser file is corrupt (literally says corrupt, unexpected end of file), how do I fix this? I can't even remove or re-install chrome (I want to remove chrome).
[14:43] <ens> rbasak: would you happen to have any other suggestions for how i would go about modernising my knowledge of ubuntu on cloud and programming stuff? i've got sysadmin and coding experience but it's pretty oldhat and i am kinda looking to get with the times.
[14:44] <ens> i have done almost nothing involving cloud stuff, usually just did on-prem stuff with mostly baremetal.
[14:45] <Helenah> Once can never complete their computer science knowledge, it's just too vast. lol
[14:45] <Helenah> You'd reach the grave trying, believe me! :)
[14:46] <ens> it's true, but it's really hard to keep up for me since i think the world has moved on a lot since my last job, and i kinda have the time to modernise my knowledge so i may as well get involved in a worthy project like ubuntu while doing it!
[14:46] <oerheks> Helenah, you might want to try to copy /var/lib/dpkg/alternatives/x-www-browser from the live iso ?
[14:47] <ens> everyone asks for cloud skills and python/go these days it seems.
[14:47] <Helenah> hmm
[14:49] <Helenah> I'm desperate for another way, what does this do?
[14:49] <Helenah> Wow that looked good!
[14:52] <BuildTheRobots> good afternoon. trying to add a custom CA certificate to my desktop machine, ideally so it's recognised in browsers. I found some old instructions for ubuntu server which I followed and which said it added the CA (`cp custom-ca.crt /usr/local/share/ca-certificates && update-ca-certificates`), but none of my browsers (chrome, ff or vivaldi) seem to recognise sites signed with it. Could anyone advise please?
[14:54] <oerheks> BuildTheRobots, did you logout/login after that? or better, reboot
[14:55] <oerheks> instructions seems right
[14:56] <BuildTheRobots> I rebooted after and then tried to open a site signed with the custom CA in ff, chrome and vivaldi and all 3 still reported it as insecure
[14:56] <TJ-> BuildTheRobots: is the added certificate in the correct format?
[14:56] <BuildTheRobots> @oerheks ^^
[14:56] <BuildTheRobots> urm, i believe it's in the correct PEM format. It has a -----BEGIN and -----END lines
[14:57] <oerheks> oh, chrome uses its own; Note that updating ubuntu system certificate store by update-ca-certificates has no effect on Chrome.
[14:57] <BuildTheRobots> iirc firefox has used it's own store for a while too
[14:58] <oerheks> 6
[14:58] <oerheks> In Ubuntu, Chrome uses its own certificate store. You can import your RootCA.crt in Chrome's settings -> privacy and security -> manage security keys -> manage certificates -> authorities
[14:58] <BuildTheRobots> found the option to add to both
[14:58] <BuildTheRobots> fantastic, thank you :)
[14:58] <BuildTheRobots> i guess i should try cli curl and see if that's happy with it (that would imply my update-ca-certificates import actually worked at a system level)
[14:58] <BuildTheRobots> (which it does)
[15:00] <Helenah> I got the answer oerheks and I would like to drop it here just incase anyone else needs it: sudo update-alternatives --remove-all google-chrome-stable & sudo rm /var/lib/dpkg/alternatives/google-chrome-stable & sudo apt-get install --reinstall google-chrome-stable
[15:00] <Helenah> Now I'm going to try and remove google chrome because I need longer use it! :3
[15:00] <Helenah> s/need/no
[15:01] <Helenah> Oh same issue! o.o
[15:01] <BuildTheRobots> thanks oerheks and TJ- :)
[15:01] <Helenah> Sigh, I'm probably just going to get the default file. :/
[15:13] <imi> I saved a file from a snap application to /tmp
[15:14] <imi> now obviously that file didn't made it to the systemwide /tmp, it's inside a chroot /tmp or whatever
[15:14] <imi> how do I find that file on my actual file system? (outside of the chroot)
[15:15] <oerheks> interesting, did that snap have access to /tmp?
[15:16] <oerheks> If so, why would it not be in /tmp but an other place
[15:16] <imi> oerheks: not to the system wide /tmp as I said. to a /tmp of a chroot
[15:17] <oerheks> that would be the same,..
[15:17] <imi> no it is not
[15:18] <imi> snaps can write to /tmp but the file written to the /tmp does not appear in /tmp (maybe overlay fs? maybe chroot? maybe both?)
[15:18] <oerheks> normally snaps are confined to the homefolder.
[15:18] <oerheks> what snap exactly?
[15:19] <imi> shapezio :) but I remember a different snap with the exact same behaviour as well
[15:20] <ens> there is a security setting that stops tmpfiles showing up for others users iirc
[15:21] <imi> same user
[15:23] <ioria> imi, maybe an /home/$user/tmp and then bind mount /tmp ?
[15:23] <oerheks> shapezio here does not have access outside the home folder.
[15:23] <oerheks> so i wonder, even with a chroot..
[15:26] <h1pot> talking about snaps, the kdenlive one isn't rendering any video
[15:31] <lavaball> cups unshares my printers. i just have to share them again and all is fine, but it would be nice if they didn't unshare themselves in the first place.
[15:44] <rbasak> ens: learn cloud-init and lxd for fast local emulation (if using an image like ubuntu:focal) maybe? Usually the way to get into this kind of thing is to have a project to do that you're motivated to finish. Difficult for others to suggest specifics then though.
[15:44] <orion__> Who is the best person with whom to speak regarding kernel build errors, specifically related to the linux-image-generic deb for Ubuntu?
[15:44] <rbasak> !ask | orion__
[15:46] <orion__> rbasak: linux-image-unsigned-$(uname -r) does not build for me. The problem is that the file-downloader in the debian/scripts directory tries to fetch a broken link.
[15:46] <orion__> Specifically: https://launchpad.net/ubuntu/+archive/primary/+files/wireguard-dkms__all.deb
[15:47] <ens> rbasak: thanks, your suggestions are really good. i've been reading up on cloud-init and lxd and it looks like surely the way to go to do a lot of learning. i'm getting some spare hardware with a decent disk size and ram size for studying with so i'll probably do what you suggest.
[15:48] <ens> rbasak: it's kinda hard to have a good project these days since for a lot of stuff i need there's some person who has already written something for it! but i guess i'll brainstorm a bit.
[15:53] <McE2> Hi, where can i learn about the dicretory structure of the ubuntu repository ; for example what are the "override.xxxx" files in http://old-releases.ubuntu.com/ubuntu/indices/
[15:55] <oerheks> The  override  files  used to make the official Packages lists may be found in the indices on any Debian mirror http://manpages.ubuntu.com/manpages/trusty/man5/deb-override.5.html
[15:56] <oerheks> just open any override file

[18:31] <Samian> I don't like the saying "you get what you pay for" because ubuntu is free even though I'd place its value in the billions and Windows and OSX cost money even though their value is less

[18:44] <colin_b> Hi, I'm new to linux (ubuntu/pop!os) and I just changed my hostname from "pop-os" to "pc-colin". After a reboot, my wired ethernet no longer works. What could be the cause?
[18:48] <sarnold> colin_b: you can use ip -c a, ip -c l, ip -c r  to see information about the interfaces, ip addresses, routing tables, and look for errors there
[18:53] <colin_b> Thanks. I can't see any error there. This is the output of the commands: https://pastebin.com/ads7S6Nj
[19:00] <thyriaen> can i set a 4th level choose of my keyboard ?
[19:01] <sarnold> colin_b: so it looks like your usb adapter should be able to talk to 192.168.61.101 -- can you ping 192.168.61.101 ? or interact with it in some other fashion?
[19:02] <oerheks> thyriaen, sure?
[19:02] <colin_b> @sarnold Yes, I can ping it
[19:03] <sarnold> colin_b: okay, cool.. how about ping 8.8.8.8?
[19:03] <thyriaen> oerheks, how do i do it ?
[19:04] <oerheks> settings, region + language , input sources
[19:04] <colin_b> No wait
[19:04] <colin_b> I was connected using USB tethering (backup for now). It can't even establish an ethernet connection: "Activation of network failed"
[19:04] <sarnold> colin_b: oh :(

[19:04] <thyriaen> oerheks, not sure we understand eachother, i would like to modyfiy my current keyboard layout in such a way that  i have an extra modifier for a 4th layer of symbols on my keyboard
[19:05] <oerheks> oh, i thought 4 keyboardlayouts
[19:05] <colin_b> @sarnold did you receive my message at 21:04:08? Had to turn off my USB ethernet for testing the command
[19:05] <thyriaen> yea, no - just one layout but a 4th layer
[19:05] <sarnold> Tue 03 19:04:30 < colin_b> I was connected using USB tethering (backup for now). It can't even establish an ethernet connection: "Activation of network failed"

[19:06] <colin_b> Ok, that's the last one. Good :)
[19:07] <sarnold> colin_b: cool; I was a bit surprised it took 22 seconds to get to irc, but maybe that shouldn't be surprising :) heh
[19:08] <noarb-> I'm researching setting up sbuild + schroots to build packages locally like the security team recommends here: https://wiki.ubuntu.com/SecurityTeam/BuildEnvironment ... How does changing the filesystem impact the procedure? does launchpad buildd use lvm like https://help.ubuntu.com/community/SbuildLVMHowto (first page mentions its an extension of this page)? I also found using debootsrap with btrfs
[19:08] <noarb-> https://gist.github.com/81887821/1bbd2ff019548ddc01e7cd989b858ef0 does my choice of fileystem to build with matter? Or, does it matter moreso than the filesystem I chose for my day-to-day workstation?
[19:12] <sarnold> noarb-: irc has line length limits, I think your first message was cut off at "using debootsrap with btrfs"
[19:14] <noarb-> Ah sorry about that. I was just wondering if my choice of filesystem to build on matters much, or moreso than the filesystem I choose for my workstation? Is it only mentioning it in case I'm building on a dedicated disk, and need to format it?
[19:15] <sarnold> noarb-: filesystem choice does matter; I found I couldn't build on my new laptop following those BuildEnvironment instructions because I used zfs for root, and the overlay stuff doesn't work there
[19:16] <sarnold> noarb-: I *think* sbuild has some support for using zfs datasets but I couldn't figure out how to use it. :( so I still do all my builds on my old laptop, with ext3 ..
[19:17] <sarnold> noarb-: you might be able to get sbuild to use btrfs subvolumes, that might be a nice improvement
[19:18] <sarnold> noarb-: the buildds probably don't do lvm, they re-use the same VMs over and over again, filesystems are never resized etc, just "cleaned", whatever that means :)
[19:18] <noarb-> Does buildd on launchpad use LVM? Would there be a benefit in matching that? https://gist.github.com/81887821/1bbd2ff019548ddc01e7cd989b858ef0 shows using btrfs; is the "improvement" build times via write speedups or caching between runs or something?
[19:18] <dale> Hi, is there some way to tell what repository an installed package came from?  I've got a docker.io package installed and I'm trying to tell if it came from Ubuntu repos or Docker repos.  Docker repos were once installed but are no longer installed.
[19:18] <oerheks> sure it is the docker repo, apt-cache policy docker
[19:19] <sarnold> dale: searching for the version string is about the best you can do, I fear
[19:19] <dale> oerheks: This looks interesting.
[19:20] <noarb-> Maybe btrfs would be like ext3 + eatmydata? So its for caching/speed? Sorry just completely naive on it, probably just overthinking it
[19:21] <sarnold> noarb-: I'm not sure if i'd expect it to be faster or slower than ext4..
[19:22] <dale> oerheks: I think this is telling me that at least the package version I have installed matches what is in the Ubuntu repos, since now all I have installed are the Ubuntu repos.  The "Installed" and "Candidate" versions are the same, and the "Version table" lists my currently-installed version in the updates/universe repository.
[19:23] <dale> So barring Docker folks releasing a package with exactly the same (long, complicated) version descriptor as Ubuntu, I think I have the Ubuntu package installed.
[19:23] <dale> Thanks oerheks, sarnold :)
[19:52] <shinobi> Is Wayland recommended over X?
[19:53] <sarnold> it depends what applications you use, what hardware you have, etc
[19:55] <oerheks> Mir or Wayland, it will be.
[19:55] <nemo> sarnold: Wayland is still experimental with firefox
[19:55] <nemo> although personally I avoid it 'cause I use X forwarding a lot
[19:56] <nemo> and X scripting
[19:56] <sarnold> nemo: heh, the two applications I use are firefox and urxvt .. I'm not rushing into wayland myself :)
[20:01] <nemo> sarnold: tried out webrender yet?
[20:02] <sarnold> nemo: heh, I'm not sure :) I've got https://bugzilla.mozilla.org/show_bug.cgi?id=1514148 "WebRender seems to ignore Expose events on X11" in my firefox history which maybe suggests I did, at some point, but maybe it was just someone else talking about it..
[20:02] <nemo> I know they are working on it, I'm just kinda apathetic
[20:03] <nemo> sarnold: X11 works for my simple needs and Webrender... doesn't.
[20:03] <nemo> sarnold: er. *wayland*
[20:03] <nemo> webrender works quite nicely indeed
[20:03] <sarnold> nemo: oh, wayland, no, never tried it.
[20:04] <nemo> So. Just fixed another issue with the 4 ubuntu machines at work.  After replacing the gnome login with slim and reducing memory usage ten-fold, the admins said that the login still wasn't working
[20:04] <nemo> turns out gnome3 now requires gl acceleration which wasn't working in the web consoles.
[20:05] <nemo> sooooo followed some instructions for purging gnome3 (which wiped X too, but I just reinstalled it) and added a basic MATE
[20:05] <nemo> all better!
[20:05] <nemo> and even less memory usage and disc space wasted
[20:07] <nemo> sarnold: well IMO you should check it out if you spend a lot of time in your web browser. seems to really help
[20:07] <nemo> even on top of layers acceleration
[20:07] <nemo> I've just run into a few edge case bugs
[20:09] <nemo> sarnold: for example https://m8y.org/tmp/testcase484.xhtml still renders blurry in webrender due to the scaling and transforms
[20:09] <nemo> actually even blurrier than in the past
[20:09] <nemo> I suspect stuff like that is low priority for them though
[20:14] <AmR> sarnold: Thanks :)
[20:18] <AmR> How I can make swap part active at system startup ?
[20:19] <oerheks> see the swap manual?
[20:19] <oerheks> !swap
[20:19] <sarnold> nemo: webrender enabled, thanks for the hint :)
[20:20] <sarnold> nemo: nice job with the vast memory savings ;)
[20:21] <nemo> sarnold: yeah, really my fault for not having used "lubuntu" in first place eh ☺  but these 4 ubuntu servers have an amusing history.
[20:21] <sarnold> nemo: hehe
[20:21] <sarnold> like most machines..
[20:21] <nemo> sarnold: When they hired me in 2007 they had 0 linux desktops or servers.  They gave me 30 minutes as admin on my assigned machine to setup "tools needed to do your job as a developer"
[20:21] <nemo> sarnold: so I installed virtualbox and ubuntu
[20:22] <nemo> er. ubuntu *inside* virtualbox.  booting to ubuntu was still technically not allowed at the time ☺
[20:22] <nemo> hm. actually... checking lubuntu's history it didn't even exist at the time
[20:23] <nemo> sarnold: anyway after many jumps from physical to virtual it eventually became nemo's personal server image and got cloned a few times.  all the stuff *not* derived from that is devuan+slim+xfce - but I guess these 4 machines ended up on gnome3 due to ubuntu defaults ☺
[20:24] <sarnold> nemo: okay most histories don't involve going *to* physical from virtual :)
[20:24] <nemo> sarnold: virtualbox → (dd|nc) → physical 1 → (dd|nc) → physical 2 → vmware image split → clone → nutanix → moar cloning
[20:25] <nemo> really, kudos to ubuntu for probably 4 flawless upgrades and effortlessly handling all that software
[20:25] <nemo> sarnold: actually, probably one transition from 32 bit to 64 bit too
[20:26] <nemo> s/software/hardware/
[20:26] <sarnold> nemo: oh yeah, I helped someone through that once after telling them not to do it, it worked out surprisingly well. heh :)
[20:26] <nemo> it's all getting fuzzy at this point
[20:53] <TurboTech> Good afternoon.
[20:56] <nemo> G'day
[21:01] <TurboTech> I have been running ubuntu for years and I had to do a new install on my computer because of broken packages and things that evolved over time with my previous 18.04 Ubuntu Studio.  I am a photographer on the side and I am having a problem with Web Ice Tea opening my ROES program.  It has worked in the past, but now it will not get past permissions of unsigned jars.
[21:07] <leftyfb> TurboTech: https://techblog.jeppson.org/2018/01/fix-icedtea-cannot-grant-permissions-unsigned-jars-error/
[21:07] <leftyfb> TurboTech: not recommended though. They disabled some ciphers for a reason. You might wan to contact your ROES vendor to update their application
[21:08] <leftyfb> TurboTech: https://www.bleepingcomputer.com/news/security/oracle-to-block-jar-files-signed-with-md5-starting-with-april-2017/
[21:09] <TurboTech> Thank you,  I contacted White House Color Lab and they have no idea about linux.
[21:09] <leftyfb> it has nothing to do with linux
[21:09] <TurboTech> I understand.  The minute you tell them linux they freak out.  They have no idea what Ice Tea is.
[21:09] <leftyfb> TurboTech: they are signing their java application with an outdated cipher(probably MD5)
[21:10] <TurboTech> I will try to contact ROES directly.
[21:10] <leftyfb> it has nothing to do with ice tea either. It's how they are signing their jar application
[21:11] <leftyfb> eventually, all java/jre clients are going to have it blacklisted so it won't work anywhere, then it becomes a bigger issue for them
[21:13] <TurboTech> I understand.
[21:15] <TurboTech> Thank you for your help
[21:28] <AmR> did ubuntu swap work with /etc/fstab or systeamd ?
[21:30] <leftyfb> AmR: on my 20.04 machine swap is listed in fstab
[21:30] <leftyfb> but it's also encrypted, so not sure if it's due to the LVM encryption
[21:37] <zekiah> Ubuntu
[21:46] <hjalp> Hi there, any ARM side devs around?
[21:49] <hjalp> I've had in issue with the latest Raspberry Pi kernel update on 21.04 (raspi-1016), I got it to boot again by importing the 1016-raspi stuff from a fresh Ubuntu Server install after the 1015-raspi broke everything, but now my iptables won't work and the OS is trying to do some sort of update (to the kernel?) every time I reboot, although  it always
[21:49] <hjalp> just ends up in 1015-raspi as a result :<
[21:50] <hjalp> ufw won't work and all that ... I've tried all possible solutions, is there a way to just rewrite the kernel headers or something
[21:50] <hjalp> This seems to be a frequently asked question and an issue especially on the Raspberry Pi side
[21:56] <hjalp> each reboot, it atm does the animated "Ubuntu 21.04" text mode screen with four dots in it (". . . ."), apparently in attempt to upgrade the kernel, just to be stuck in 1015-raspi again when it boots up after a few minutes of that
[21:57] <hjalp> also I don't understand how Ubuntu Server was apparently able to install 1017-raspi of that same 5.11.0 kerneltree but Xubuntu hasn't got that available at all
[21:58] <waveform> hjalp, the typical method for (at least temporarily) stepping down to a lower kernel version is to use "sudo flash-kernel --force <version>" assuming the <version> specified is still installed, e.g. "sudo flash-kernel --force 5.11-1015-raspi" but be aware that's only a temporary solution; the next kernel upgrade will run flash-kernel fresh which will copy the latest installed kernel to the boot partition
[22:00] <hjalp> waveform thanks for the reply! however it doesn't work apparently because it can't find DTB bcm2711-rpi-4-b.dtb from /etc/flash-kernel/dtbs and some other directories
[22:00] <waveform> hjalp, the four dots on the boot screen are not a kernel upgrade attempt; that's just plymouth presenting a "pretty" boot screen during boot-up though I'm a little confused why that's appearing -- it's not on by default in ubuntu server, and ubuntu desktop images present a graphical "spinner" instead (though I'm not familiar with what xubuntu images do unfortunately)
[22:01] <waveform> hjalp, what's in "/boot"? (and I do mean /boot and not /boot/firmware -- the former is where flash-kernel is looking for "available" kernels and dtbs)
[22:02] <hjalp> waveform after the kernel update at around 1014-raspi fried my Ubuntu builds, I had to wait for a kernel upgrade to Ubuntu Server (even on that side, on a brand new USB install, the OS was just booting to the rainbow of death)
[22:02] <waveform> if you specify something like "sudo flash-kernel --force 5.11-1015-raspi" it will expect to find "/boot/vmlinuz-5.11-1015-raspi" (and initrd.img, etc.)
[22:02] <hjalp> waveform oh, you were missing the .0. in between
[22:03] <hjalp> it's 5.11.0 -
[22:03] <waveform> ah, that's me being dumb :)
[22:03] <waveform> yup, should be "sudo flash-kernel --force 5.11.0-1015-raspi"
[22:04] <hjalp> it still doesn't work ... hmm ... there is a symlink for dtb -> dtbs/5.11.0-1016-raspi/./bcm2711-rpi-4-b.dtb
[22:04] <hjalp> what if instead of 1015 I'll try to just redo the 1016 ?
[22:05] <hjalp> that seems to work
[22:05] <waveform> the symlinks are all largely ignored on raspi -- they're used on PC installs with grub though
[22:06] <hjalp> yeah that's the biggest head scratcher in all of these types of situations when some of the features from the PC side are implemented in the bootloader and others are not ...
[22:06] <hjalp> waveform ok so I ran that for 1016-raspi,  should I just reboot now or ?
[22:06] <hjalp> that seems  to have been successful
[22:06] <waveform> yup, if it's run successfully then that's effectively "installed" that kernel (and its associated initrd, and dtbs) to the boot partition
[22:07] <waveform> (which will require a reboot to operate)
[22:07] <hjalp> we'll see ... yep, I'm reboot ing
[22:07] <hjalp> @wavef btw after that complete OS-incapacitating thing with around 1014-raspi
[22:08] <hjalp> ... the boots have been really slow (sorry, typoed) waveform
[22:08] <hjalp> from what I've gathered it's running a forced fsck in the early boot and editing /etc/fstab didn't help , etc ...
[22:09] <hjalp> @waveform no idea what's that about, especially since my other build worked just fine after getting a "boot-transplant"
[22:11] <hjalp> viewing with esc underneath the splash screen reveals that it runs a thorough disk check; this is something that happened only after the failed update: and on this machine the iptables are now somehow broken, I get a bunch of dmesg errors etc, not even ufw is starting up properly :<
[22:11] <waveform> hjalp, I can't say I'd heard of the OS-incapacitating thing -- been happily running 1015 here on my hirsute installs. Do you happen to remember where you got your xubuntu image? I'm only seeing PC images on the xubuntu.org site, but I'd like to try and replicate something this severe
[22:12] <waveform> (will probably have to be tomorrow though -- it's past 11PM here at the moment)
[22:13] <hjalp> waveform https://askubuntu.com/questions/1353872/raspberry-pi4b-64bit-21-04-5-11-kernel-trees-1014-raspi-1015-raspi-apt
[22:13] <hjalp> waveform ok thanks, now it's at least back to 1016-raspi
[22:14] <hjalp> however I get no driver for the bcm2711; that seems to have been broken as well.
[22:14] <hjalp> my iptables aren't working in either one of the available modes
[22:14] <waveform> do you have a specific error for the bcm2711 driver? (there's a lot of drivers for the SoC :)
[22:17] <hjalp> not really -- hmm , how should I start looking for that one? I noticed that I've had no sound (I rarely use audio) since that botched apt update
[22:17] <hjalp> waveform on this RPi4B to be specific, in the other one that I fixed with the same trick as mentioned in that AskUbuntu link ,everything's working a-ok, no boot delays, no broken iptables, no audio issues ...
[22:18] <hjalp> at least sudo dmesg | grep bcm doesn't bring much up
[22:19] <hjalp> ok well at least pulseaudio isn't loaded as a server
[22:19] <hjalp> (but it's running as a daemon)
[22:20] <hjalp> (although the config says 'Daemonize = no' ? )
[22:21] <waveform> hjalp, I've no particular ideas about the audio other than to check that "dtparam=audio=on" is somewhere in /boot/firmware/config.txt (prior to any dtoverlay= lines) which is required to enable the audio hardware
[22:23] <hjalp> waveform how about the iptables? as I began to look that one up, I only found references to kernel mismatches (which indeed seems to be the case atm)
[22:23] <hjalp> I can't basically plug that in the internet atm since ufw isn't loading up
[22:23] <waveform> hjalp, on boot messages, "journalctl -b" is usually enough to bring up the necessary bits, but sometimes there's extras in /var/log/syslog which can be useful
[22:25] <waveform> hjalp, on iptables do you see a specific error when you try something like "sudo iptables -L -n"?
[22:25] <hjalp> waveform also the fsck after every boot is a bit of a ?; I'm wondering if there's a method to check out what's forcing into that with each boot; I dont' have the "forcefsck" file in "/" , /etc/fstab has 0 , 0 for both partitions etc.
[22:26] <waveform> hjalp, well let's sort out that you're actually *getting* an fsck first -- are you seeing a message actually saying it's fsck'ing?
[22:27] <hjalp> it's not showing up anything else except after the "jam" is cleared, it says ..itable clean: checked blah out of blah bytes ("...itable" because I can't read what's in there since it draws it out of the screen)
[22:27] <hjalp> failed to start "set up additional binary formats", failed to start "Uncomplicated Firewall" ...  Starting of Arbitrary Exec..Automount Point not supported ...
[22:29] <waveform> on systemd there's a systemd-fsck@ service which is instanced to all the mounted disks; I'm not familiar enough with it to know what its criteria are for bothering to check, but that's the next place probably worth checking
[22:30] <waveform> what's also a bit confusing is that you've got the -1016 kernel at all -- that's only in -proposed from what I can see; did you enable proposed to test a kernel release?
[22:32] <hjalp> @waveform alright I'm checking that out
[22:33] <hjalp> waveform -- iptables/1.8.7 Failed to initialize nft: Protocol not supported
[22:34] <hjalp> waveform ... and hence ufw doesn't work either -- I've tried switching to the legacy mode with 'sudo update-alternatives', but in that one ufw says that there's some mismatch that likely requires kernel update
[22:35] <hjalp> waveform yes, I have the proposed repo enabled, but that doesn't explain how it still wouldn't work when I reverted all the way back to 1014 or so
[22:36] <waveform> hjalp, it would depending on what else you've got installed from there. If you've enabled proposed across the board (without pinning), you can pretty much expect breakage at some point; just reverting the kernel version isn't going to avoid that
[22:36] <hjalp> running waveform iptables-restore/1.8.7 says the same; "Failed to initialize nft: Protocol not supported"   https://raspberrypi.stackexchange.com/questions/120322/ufw-error-couldnt-determine-iptables-version <= pretty much close to that
[22:37] <luigi>          n  cb
[22:37] <hjalp> waveform disable proposed and downgrade all?
[22:38] <waveform> frankly I'd consider just re-installing if you've enabled proposed and upgraded everything, but if that's impractical for some reason, then yes -- that'd be the sensible next step
[22:39] <waveform> it does sound like you've got a mismatch between the kernel that's being booted (from /boot/firmware) and what's installed on the root partition (specifically it sounds like iptables is failing to load various nft_* modules)
[22:40] <hjalp> well, I've got 9901 installed packages now that I checked, so I'd rather not reinstall from scratch, but ...
[22:41] <hjalp> aside this complete apt-update related bootloader collapse glitch everything's been running fine
[22:43] <waveform> I've got to head off now, but I'll try and reproduce the upgrade issue tomorrow based on that bug-report
[22:44] <hjalp> waveform it was fixed some time after that, I wonder if part of the mismatch is because I took the boot stuff from a Ubuntu Server and stuck into the Xubuntu
[22:46] <hjalp> waveform thanks for the help tho ... I'm rebooting now but systemd-udevd is hanging up (am still waiting)
[22:48] <hjalp> waveform btw, I have another build that's working perfectly and it's the same Xubuntu 21.04 that I fixed the same way (it doesn't have any boot delay btw, works like a charm)
[22:48] <hjalp> I'm wondering if I should just grab its files or something
[23:53] <obztrack> Hi i would like to know if there any big difference between Mint and Xubuntu for playing game on Steam on a tiny laptop?
