package mysql-server-5.1 5.1.41-3ubuntu12 failed to install/upgrade: Package is in a very bad inconsistent state - you should reinstall it before attempting a removal. cant stop mysql server to reinstall it

Do you have a mysql root password set?

Regards
chuck

Hi, chuck
What do you mean? Mysql root password is not empty. Should i put it somewhere?
I've read on the ubuntu forum that it's actually a problem with mysql
upstart script.. So at first i was doing "sudo -u mysql mysqld" after
each boot, then i copied an init.d script from an other machine. Both
solutions work, so the problem is not with mysql.

Here is some stuff from my experience:

Just freezes, and stays in memory forever. Same thing in the case of the install. I cannot get removed, nor installed.

Sorry...just sticks there forever at the ... ending in my last comment.

This looks like it is a duplicate of bug #551130 (https://bugs.launchpad.net/ubuntu/+source/mysql-dfsg-5.1/+bug/551130)

Hey i ran the above command but does not work for me..........then i ran the following command ,the same problem accours...terminal freezes and does not show anything..........

sudo service mysql stop

it means there is some problem in mysql thats why mysql is not stopping and upgrade is not happening....
