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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1939251 Title: nvidia driver crashes after kernel upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1939251/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
