[Bug 835715] Re: package mysql-server-5.1 5.1.54-1ubuntu4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 100

[James Page]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.

The error you experienced in 4. was due to the apparmor profile provided
with mysql-server.  By default is will only allow access to
/var/lib/mysql so when you moved to to /srv it denied access - you can
see this in dmesg.txt:

[ 8232.324109] type=1400 audit(1314483729.470:59): apparmor="DENIED" operation="mknod" parent=1 profile="/usr/sbin/mysqld" name="/srv/mysql/caes-srv-00.lower-test" pid=30379 comm="mysqld" requested_mask="c" denied_mask="c" fsuid=0 ouid=0
[ 8232.324158] type=1400 audit(1314483729.470:60): apparmor="DENIED" operation="mknod" parent=1 profile="/usr/sbin/mysqld" name="/srv/mysql/caes-srv-00.lower-test" pid=30379 comm="mysqld" requested_mask="c" denied_mask="c" fsuid=0 ouid=0
[ 8232.326361] type=1400 audit(1314483729.470:61): apparmor="DENIED" operation="open" parent=1 profile="/usr/sbin/mysqld" name="/srv/mysql/mysql/plugin.frm" pid=30379 comm="mysqld" requested_mask="r" denied_mask="r" fsuid=1003 ouid=1003

To support this move you would need to update
/etc/apparmor.d/usr.sbin.mysqld - use the configuration for
/var/lib/mysql as a guide.

I can't tell from the attachments what failed when you tried to
uninstall mysql-server.  It looks like its still installed by not
configured - please could you try removing it again and attach the
output to this bug report.

Marking importance as 'Low' as I think this is related to the move of
/var/lib/mysql and 'Incomplete' pending your response.

Thanks
