Comment 10 for bug 501655

@ 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.
