Hello and thanks for this bug report. From the attached terminal log I guess you manually interrupted the upgrade process at some point. Was it stuck, and for how long?
In general there isn't really enough information here for a developer to confirm this issue is a bug, or to begin working on it, so I am marking this bug Incomplete for now. If you can provide exact steps so that a developer can reproduce the original problem, then please add them to this bug and change the status back to New. ** Changed in: mysql-8.0 (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/1926931 Title: package mysql-server-8.0 8.0.23-0ubuntu0.20.04.1 failed to install/upgrade: installed mysql-server-8.0 package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1926931/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
