The 5.11.0.-22 does not boot. I really would like to know how to find what's missing for it to work.

Any tools or tips to find out?

    What OS & release are you using? Ubuntu 20.04 LTS using the HWE kernel is still on the 5.8 kernel, as 5.11 is still in testing for 20.04. Are you using Pop OS or another OS & thus the testing software? as Ubuntu doesn't yet have 5.11 (due on 20.04.3; current is still 20.042) packages.ubuntu.com/…

  • If you purpose is QA-testing, then thank you, however this site recommends you file bugs so issues can be fixed before they reach end-users. help.ubuntu.com/community/ReportingBugs Thank you for helping make Ubuntu better.

  • I'm not doing any QA, I need a stable system, so this is a bug it seems. I need to know why this occured. lsb_release -a ``` No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04.2 LTS Release: 20.04 Codename: focal ```

  • If you're using 20.04 and want a stable system, then I'd check your sources, as you're not using the stable HWE kernel, but a testing (5.11) kernel currently still in QA before it reaches end-users (who are still on 5.8). Pop OS however uses the 5.11 kernel which is why I mentioned it (they use testing willing to accept glitches more readily to get newer features for newer hardware faster). I would look where it's from (apt-cache policy) and check your sources as stable 20.04.2 uses 5.8 kernel still. Your system has been opened up for -proposed or still in QA software I'm betting.

    Even -proposed for focal still has 5.8.0-61.generic, 5.4.0-79 & older kernels available for focal, so check your sources (if not obvious there, then apt logs) as you're using a (a) manually installed testing kernel, (b) not using Ubuntu 20.04, or (c) have corrupted your sources (5.11 is used by hirsute or 21.04 and not 20.04; at least not yet - that will occur at 20.04.3)

I have the same problem after doing the recommended update. I also run the 20.04.2 LTS OS and as I am a newbee, I don't experiment with the kernel or system. The recommended update went through then it won't boot up. My workaround is to use the Grub troubleshooting option and to select the previous 5.8 kernel and the system works normally.

  • Booting to the previous kernel version is a God send sometimes. Make sure you pin that kernel version so you don't accidentally loose it. Jul 7, 2021 at 0:41
  • Beware, if you re-install the nvidia meta package from the command line in the newer kernel it may impact the previous kernel as well. You may then also be able to fall back to any discrete graphics by purging the nvidia driver until there is a fix for this.
