Noting that I had this problem too... and like wannabeelinux my mysql datadir was non-default.
MySQL runs just fine pre-update (with some tweaking of the apparmor directory access config), but it's possible that the upgrade script assumes a datadir location. I have it simlinked to the default directory for convenience, so it's possible that a test for /var/lib/mysql passes even though the actual data is elsewhere (on another filesystem). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1075251 Title: package mysql-server-5.5 5.5.28-0ubuntu0.12.04.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.5/+bug/1075251/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
