[Bug 501655] Re: package mysql-server-5.1 5.1.37-1ubuntu5 failed to install/upgrade: subprocess installed pre-removal script returned error exit status 1

@ Brian, you are right. I am right now able to pull up the web page
where I read about "debian-sys-maint" users, it said that Ubuntu uses
"debian-sys-maint" to update/upgrade MySQL installations. The bad thing
that happened with me was the update went fine and my MySQL
installation, MySQL.users table, was corrupted. My root account was no
more valid. I wasn't able to stop MySQL. I had to kill it either using
kill command or system monitor. Once MySQL was down I backed up my data
folder and ran the mysqlupgrade script. May be this all due to missing
"debian-sys-maint" account in mysql.users table. I just noticed that
even in my backed up mysql.user tables there is no "debian-sys-maint"
user. I will spend some more time on it and will try to find out the
pages and other related resources.
