[Bug 1939251] Re: nvidia driver crashes after kernel upgrade

[Chris Guiver]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Please don't post/attach a .crash file.  The crash file should be
submitted using the `ubuntu-bug /var/crash/[filename].crash` which
gathers more details and populates fields making the .crash file much
easier to explore.

I suggest you submit that file, as this report is incomplete; you've
tagged it related to `ubuntu-release-upgrader` but you've not used that
tool (it would have upgraded your system to 20.10; ie. it's the tool
that upgrades you from one release to the next (20.04 to 20.10, or 20.04
to 22.04.1) and doesn't relate to a normal 'dist-upgrade'.

This issue likely relates to the HWE kernel, as recently the 5.8 kernel
stack (from 20.10) was moved to 5.11 (from 21.04) and thus package
likely should have been `linux-generic-hwe-20.04` (ie. switch to newer
5.11 is your issue).  (LTS releases have two kernel stack choices; GA
the more stable stays on 5.4, HWE upgrades during the first ~two years
of life).

I'll mark this 'incomplete' allowing you to submit your crash file and
create a new bug.  If you believe I've in error, or made an error,
please leave a comment saying why, and the bug report status can be
returned to "New".

** Package changed: ubuntu-release-upgrader (Ubuntu) => linux (Ubuntu)

** Changed in: linux (Ubuntu)
       Status: New => Incomplete

Title:
  nvidia driver crashes after kernel upgrade

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  My two older Zotacs use the NV 340.108 driver and both are having the
  same issue. After the latest dist-upgrade they boot fine but don't
  display video, just a blank black screen with a randomly blinking
  cursor. They're headless but I got into both with ssh in order to
  uninstall the NV driver and now both boot normally but just use the
  Nuveau default driver. Unfortunately I can't use either computer like
  this (no NV driver). Afterward, I tried installing the NV driver with
  Software-Updater but then received this warning after a few minutes:

  Error while applying changes
  pk-client-error-quark: Error while installing package: installed nvidia-340 package post-installation script subprocess returned error exit status 10(313)
