I got this error upgrading as well. Error files in /var/log/mysql were empty. The problem seems to be the line /lib/init/apparmor-profile-load usr.sbin.mysqld in the startup script /etc/init/mysql.conf
since when I run it manually: root@brixton:/root# /lib/init/apparmor-profile-load usr.sbin.mysqld bash: /lib/init/apparmor-profile-load: No such file or directory After commenting out this line, apt-get -f install continues as expected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/907465 Title: package mysql-server-5.5 5.5.17-4ubuntu6 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/907465/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
