Thank you for taking the time to file a bug report. From the logs we can see:
mysqld is running as pid 16349 Error: Unable to shut down server with process id 16349 Do you have by any chance another mysqld process running not managed by the Debian package provided by Ubuntu? I am asking that because I searched for PID 16349 in the mysqld error log and this PID is not referenced there. If you have a mysqld process already running, please kill it before installing the package. Since there is not enough information in your report to begin triage or to differentiate between a local configuration problem and a bug in Ubuntu, I am marking this bug as "Incomplete". We would be grateful if you would: provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to "New". For local configuration issues, you can find assistance here: http://www.ubuntu.com/support/community ** Changed in: mysql-8.0 (Ubuntu) Status: New => Incomplete ** Summary changed: - package mysql-server-8.0 8.0.26-0ubuntu0.20.04.2 failed to install/upgrade: installed mysql-server-8.0 package post-installation script subprocess returned error exit status 1 + package mysql-server-8.0 8.0.26-0ubuntu0.20.04.2 failed to install/upgrade: Unable to shut down server with process id 16349 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938640 Title: package mysql-server-8.0 8.0.26-0ubuntu0.20.04.2 failed to install/upgrade: Unable to shut down server with process id 16349 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1938640/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
