[Bug 444349] Re: package mysql-server-5.1 5.1.37-1ubuntu4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Thomas M Wetherbee]

I had this problem on a vanilla update from jaunty to karmic. Everything
seemed to update okay, but later when I went to run a MySQL backup I
couldn't do it. It was only then that I realized that karmic included an
"upgrade" to MySQL 5.1. The upgrade had not completely worked.

I went in and tried reinstalling from Synaptic, and that's when I got
this error. This caused me a lot of trouble. Not finding the exact cause
of the error, I tried going back to 5.0, and ultimately purged MySQL and
tried a fresh install. Even that didn't work. Of course purging caused
many of my installed applications to be removed, so it's been an ongoing
hassle.

The GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor=0" work-around
allowed me to install and configure MySQL 5.1. At this point things are
looking good, although my testing has been very limited. I haven't
looked at what went wrong with apparmor; perhaps someone here will
explain it and save me the trouble.

This is the second update in a row that had some major failure for me
(jaunty and karmic). I am a technical user, and I keep my systems in
good order, so it is disappointing that we are seeing this sort of
update trouble. I understand that upgrades are a major support hassle,
but if we want common users to embrace Ubuntu we are going to need a
smooth upgrade process. Perhaps the six month upgrade cycle is too
aggressive?
