Hi Christian, as Lucas wrote there is not enough information here to differentiate between a local configuration problem and a bug in Ubuntu, however there is also another problem: Ubuntu only supports upgrading from one version to the next version, or from one LTS version to the next LTS version. This means that the correct upgrade path for your setup would have been:
17.10 -> 18.04 LTS 18.04 LTS -> 20.04 LTS Jumps like 17.10 -> 20.04 LTS may in most cases just work, but are not supported. In your case I suggest you to fully uninstall any mysql package, complete the upgrade and then reinstall mysql. The Ubuntu community can help you in this kind of operation: http://www.ubuntu.com/support/community Since the reported problem arose during an unsupported operation I think the final status of this bug is Won't Fix, however I'm setting it to Incomplete just in case you don't agree with my conclusions. You know already the "change status back to New after commenting". ** 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/1881667 Title: package mysql-server-8.0 8.0.20-0ubuntu0.20.04.1 failed to install/upgrade: package is in a very bad inconsistent state; you should reinstall it before attempting configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1881667/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
