Hello Karoly and thanks for this bug report. auth_socket.so is now shipped as part of the mysql-server-core-8.0 package:
$ apt-file search auth_socket.so mysql-server-core-8.0: /usr/lib/mysql/plugin/auth_socket.so The package is installed as a dependency of mysql-server-8.0. Even if that's not the culprit, looks like you're facing an actual issue. If you believe that's a bug in Ubuntu, could you please provide us with steps to reproduce the problem from a clean Focal system? Thanks! ** 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/1972046 Title: mysql-server-8.0.postinst tries to install nonexistent plugin and sets the wrong permissions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1972046/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
