Your bug misses the error logs one would usually attach, but from the bit I see it seems your server failed to (re-)start.
But a service (re)start is a requirement for an upgrade - since the file is missing I recommend you check /var/log/mysql/error.log which often has more info why it failed to start. Resolving these issues you find in there and re-installing the package usually helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890029 Title: package mysql-server-8.0 8.0.21-0ubuntu0.20.04.3 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/1890029/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
