Thank you for taking the time to report this bug and helping to make Ubuntu better.
Bug reporting is mostly about finding & fixing problems thus preventing future users from hitting the same bug. I suspect a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu. You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709 FYI: from what I can see; you upgraded from hirsute (21.04) to impish (21.10) less than 1 day ago; and it was this upgrade that you seem to think was from impish to impish. You've listed the issue as relating to the ubuntu-release-upgrader or what upgraded your system from hirsute/21.04 to impish/21.10; yet that appears to be have successful to me; but instead need support on your now impish/21.10 system with its newer kernel & software. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1949775 Title: System is unusable (crashes) after screen is turned off and afk system must then be hard rebooted to recover.
