Thank you for taking the time to report this bug and helping to make Ubuntu better.
I see no evidence of a system upgrade (from 20.10 to say 21.04) having taken place... the installation media was 21.04 & system is still currently 21.04, thus package was changed from `ubuntu-release-upgrader` to the `linux` kernel. Bug reporting is 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 ** Package changed: ubuntu-release-upgrader (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1932528 Title: Touchpad stopped working after using as a tablet To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1932528/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
