Common reasons for that are a) flaky behavior on start/stop of the service (usually resolved by re-triggering the upgrade) b) (more common) having another service, maybe even a 3rd party mysql/mariadb server that runs and blocks that port You'd need to resolve this local config issue and the upgrade should then complete again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1906976 Title: package mysql-server-8.0 8.0.22-0ubuntu0.20.04.3 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/1906976/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
