By chance, when you reinstalled did you manually delete /etc/mysql/conf.d? (The installer might not be accounting for manual steps done when removing the old package.)
Also, at one point did you have mariadb installed? I notice a mention in your logs: Start-Date: 2022-01-16 18:13:21 Commandline: apt install libmariadb-dev Requested-By: jarjan (1000) (mariadb is known to interfere with mysql since they have some files named the same way. To work around that it can be worth force purging mariadb before fresh-installing mysql, and vice versa.) ** Changed in: mysql-8.0 (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958641 Title: Apport hook failures: missing conf dir; add_info() takes 1 positional argument but 2 were given To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1958641/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
