=== cpaelzer__ is now known as cpaelzer [07:25] Kernel 5.9 released [16:48] Hello, where do i report kernel problems ? [16:49] luna_, you mean *Ubuntu kernel* issues? You can use Launchpad, to open a bug: https://bugs.launchpad.net/ubuntu/+source/linux/+filebug [16:50] gpiccoli: alright tried to manually update to kernel 5.9 using these packages: https://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/amd64/ but dkms did not load the zfs modules so i got stuck with an angry message in busybox, no zfs modules loaded [16:51] hmm...so, did you install the headers packages to allow dkms to build zfs? [16:52] gpiccoli: yep installed the headers_all package [16:53] did you manage to check if dkms built the zfs module for this kernel version? The suggestion I can give you is to reboot in a working kernel, and be sure dkms can build the zfs module for the daily 5.9 kernel luna_ [16:54] gpiccoli: i did reboot to the 5.8 kernel now, how can i check if dkms can build for 5.9 ? [16:55] try this: find /lib/modules/ | grep -i zfs [16:55] let me know the results [16:56] https://pastebin.com/ivip547w [16:56] ok, clearly you don't have zfs modules to 5.9.x [16:56] only for 5.8.0-18 and 5.4.0-42 [16:56] can you pastebin the output of "dpkg -l | grep -i zfs" ? [16:57] https://pastebin.com/jA6X0zyU [16:59] what is the output of "dkms status" luna_ ? [17:00] virtualbox, 6.1.14, 5.8.0-18-generic, x86_64: installed [17:00] virtualbox, 6.1.14, 5.8.0-19-generic, x86_64: installed [17:00] virtualbox, 6.1.14, 5.8.0-20-generic, x86_64: installed [17:00] virtualbox, 6.1.14, 5.8.0-21-generic, x86_64: installed [17:03] now, last pastebin: "dpkg -l| grep -i dkms" [17:03] https://pastebin.com/suGPB1td [17:05] hmm..you don't have even a dkms zfs package, it seems. Try to run "apt-get install zfs-dkms" [17:05] let's see how it goes [17:05] After if finishes the installation/build, if all goes fine, try again: "find /lib/modules/ | grep -i zfs" [17:05] see if there are zfs files under 5.9.x/ folder [17:09] nope [17:11] still missing [17:12] try "apt-get install zfs-linux" then, please [17:13] apt could not find that package [17:13] yeah, I'm sorry..it's a source package, my bad [17:13] Do you have any logs from dkms ? [17:14] let me try to install the same kernel you're trying and see if I can have zfs installed too [17:14] gpiccoli: sure i guess so but not sure where they are located /var/log/something ? [17:14] BTW, are you using Ubuntu 20.04 luna_ ? [17:14] nope, i am trying out 20.10 [17:14] 20.10, great! [17:14] let me try here, will get back to you [17:15] using rolling rhino :p [17:15] alright :) [17:15] dkms logs should be on /var/log [17:15] find /var/log | grep -i dkms get you nothing ? [17:15] nope [17:16] BTW, did you install both headers packages luna_ ? [17:16] There is a _all and a -generic that must be installed [17:16] ah that might be the problem then [17:17] try that, while I'm trying here hehe [17:17] did not install the -generic one [17:18] and now, after installed the -generic one, did it work ? [17:18] still installing [17:19] dpkg failed installing it [17:20] uh? [17:20] Why? [17:20] if possible, please pastebin the logs [17:21] got an error message in Swedish so not sure how helpful that is [17:21] hmm..yeah, not useful for me lol [17:22] https://pastebin.com/HnwrbC14 [17:23] saying something about dependency problems [17:25] hmm..odd! So, the steps to make it work are: you need the following packages properly installed : https://pastebin.ubuntu.com/p/wCSSpr6Dn4/ [17:26] after that, if zfs-dkms is already installed, it should build you zfs for that kernel [17:26] if not, installing it will trigger the build [17:26] alright [17:26] you can try now to remove/purge the 5.9 kernel of your system and reinstalling it using the "dpkg -i *" in a folder with the 5 necessary DEBs [17:27] I'm still running this process [17:29] making a second try here now too [17:30] ok! [17:31] nah getting some problem while trying to install linux-headers-5.9.0-050900daily20201012-generic and dkms does not want to do its thing :( [17:32] gpiccoli: sticking with 5.8 for now, but thanks for the help in trying to troubleshoot [17:32] my VM is slow and still building dkms, let's see how it goes [17:33] alright i will stick around [17:33] if you want to continue trying the 5.9, you could change your locale to english and pastebin the outputs, we can try to make that work [17:33] should be a harmless process... [17:33] it's very common to install kernel packages [17:34] getting a bit too tired, will just stay around with 5.8 until you push 5.9 in the repos later [17:35] Hmm..I think the problem is this: [17:35] Loading new zfs-0.8.3 DKMS files... [17:35] Building for 5.4.0-48-generic 5.9.0-050900daily20201012-generic [17:35] [...] [17:35] Building initial module for 5.9.0-050900daily20201012-generic [17:35] ERROR (dkms apport): kernel package linux-headers-5.9.0-050900daily20201012-generic is not supported [17:35] Error! Bad return status for module build on kernel: 5.9.0-050900daily20201012-generic (x86_64) [17:35] Consult /var/lib/dkms/zfs/0.8.3/build/make.log for more information [17:36] I'll read the logs, but seems zfs cannot build in this kernel version [17:36] guess you Kernel, ZFS and Canonical people have something to work on then :D [17:36] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1899515 [17:36] Ubuntu bug 1899515 in linux (Ubuntu) "ZFS Modules Missing" [Undecided,Incomplete] [17:36] if you wanna add something more sensible to my bug [17:37] ok, I'll do! [17:37] thanks for reporting the bug [17:42] no problem, have fun working on it [17:44] thanks luna_ hehe [17:44] Keep following the LP! Let's see how it goes [17:54] will do [17:56] =] [20:45] the zfs module always needs porting to a new kernel version [20:46] aiui that work has only started for 5.9 [22:39] yeah, that's always an issue with out-of-kernel modules
