[Bug 686805] Re: package mysql-server-5.1 5.1.37-1ubuntu5.5 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Hi Dan, thanks for taking the time to submit this bug report and help us
make Ubuntu better.

THis line from daemon.log suggests that maybe this was just a temporary
problem while restarting the service after upgrade:

Dec  7 15:24:13 ubuntu mysqld: 101207 15:24:13 [ERROR] Can't start server: Bind on TCP/IP port: Cannot assign requested address
Dec  7 15:24:13 ubuntu mysqld: 101207 15:24:13 [ERROR] Do you already have another mysqld server running on port: 3306 ?
Dec  7 15:24:13 ubuntu mysqld: 101207 15:24:13 [ERROR] Aborting

This can happen if you have a lot of connections churning on your server
when the restart is done, as it may take a couple of seconds before the
LISTEN socket is unbound from the interface. If you can stop all clients
from accessing the server before an update, that will probably prevent
this from happening.

You may want to just try

sudo service mysql start

If that works, finish the update by running

sudo dpkg --configure -a

Marking Invalid as this does not appear to be a bug.

** Changed in: mysql-dfsg-5.1 (Ubuntu)
       Status: New => Invalid
