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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1939251 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) OK ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: ubuntu-release-upgrader-core 1:20.04.35 ProcVersionSignature: Ubuntu 5.11.0-25.27~20.04.1-generic 5.11.22 Uname: Linux 5.11.0-25-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.18 Architecture: amd64 CasperMD5CheckResult: skip CrashDB: ubuntu CurrentDesktop: ubuntu:GNOME Date: Sun Aug 8 18:05:04 2021 InstallationDate: Installed on 2021-02-24 (165 days ago) InstallationMedia: Ubuntu 20.04.1 LTS "Focal Fossa" - Release amd64 (20200731) PackageArchitecture: all ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: ubuntu-release-upgrader Symptom: dist-upgrade UpgradeStatus: No upgrade log present (probably fresh install) mtime.conffile..etc.update-manager.release-upgrades: 2021-02-24T10:56:52.723450 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1939251/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
