Same thing happened to me when upgrading from 19.04 to 19.10. The upgrader froze, after about an hour I rebooted and had to manually fix the upgrade process. Removing mysql-server completely (also mysql- server-8.0 and dependencies) and install again gives this:
ERROR: Unable to start MySQL server: mysqld: Can't read dir of '/etc/mysql/conf.d/' (OS errno 2 - No such file or directory) mysqld: [ERROR] Fatal error in defaults handling. Program aborted! Please take a look at https://wiki.debian.org/Teams/MySQL/FAQ for tips on fixing common upgrade issues. Once the problem is resolved, run apt-get --fix-broken install to retry. dpkg: error processing package mysql-server-8.0 (--configure): installed mysql-server-8.0 package post-installation script subprocess returned error exit status 1 I tried to have apparmor ignore mysql like the last comment here: https://askubuntu.com/questions/1091803/unable-to-install-mysql-with- cant-read-dir-of-etc-mysql-conf-d-error but that doen't change anything. Might or might not be a Ubuntu issue, but before the upgrade I had mysql running (for years) and now I can't install it.
