The pre-start checks include a re-load of the apparmor profile: Error del analizador AppArmor para /etc/apparmor.d/usr.sbin.mysqld in /etc/apparmor.d/usr.sbin.mysqld en la l?nea 9: No se pudo abrir <<abstractions/mysql>>
Please can you check that /etc/apparmor.d/abstractions/mysql is installed and if it is not then try re-installing apparmor: sudo apt-get install --reinstall -o DPkg::Options::="--force-confmiss" apparmor Hopefully this will resolve your issue. I don't think this is actually a bug but a problem with your local install - marking 'Invalid'. ** Changed in: mysql-5.5 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to mysql-5.5 in Ubuntu. https://bugs.launchpad.net/bugs/1024222 Title: package mysql-server-5.5 5.5.24-0ubuntu0.12.04.1 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/1024222/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
