Thanks Andreas - true but I think this was a symptom rather than a cause. That lock issue was happening after I ran
sudo dpkg --configure -a This kept hanging with the message "This installation of MySQL is already upgraded to 5.7.25, use --force if you still need to run mysql_upgrade" I believe the error report got generated after one of these. Trying to get this resolved, I'd restarted several times but kept getting into the same locking issue as long as I tried to make the mysql-server upgrade clear its installation state. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1817374 Title: mysql-server-5.7 5.7.25 upgrade did not complete properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1817374/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
