Since restoring from a backup mySQL won't start
I have a Ubuntu 12.04.3 LTS (GNU/Linux 3.8.0-29-generic x86_64) droplet which I ballsed up by attempting to upgrade Ubuntu.
So I restored it to a backup from 1 week ago. However, I can't for the life of me seem to get mySQL to start. After restoring mySQL comes up for a matter of minutes and then dies refusing to start again.
Looking in syslog, it seems to die when this comes up:
Apr 3 23:47:25 localhost kernel: [ 360.410338] type=1400 audit(1428101245.773:24): apparmor="STATUS" operation="profilereplace" name="/usr/sbin/mysqld" pid=2456 comm="apparmorparser"
Trying service mysql start come back with this:
start: Job failed to start
Does anyone have any idea what might be happening please?
