After upgrade to 12.04 mysql server was unable to start.
I tried many different things but without any luck.
Now when I try to install it, I get:
$ sudo apt-get install mysql-server-5.5 Reading package lists... Done Building dependency tree Reading state information...

Can someone suggest some way to fix this or I must to reinstall entire system?
Thanks in advance.
