[debian-mysql] Bug#682232: Bug#682232: mysql-server-5.5: Fails to upgrade squeeze -> wheezy, does not start

[Clint Byrum]

Hi Sergio, thanks for taking the time to report a bug.

Can you include your entire /etc/mysql/my.cnf And also a listing of 
your datadir (usually /var/lib/mysql). I think the answer, since you 
have no innodb tables, is to rm /var/lib/mysql/ib*. I have tested the 
squeeze -> wheezy upgrade and it worked ok for me in the simple case of 
an empty database without any innodb tables, but perhaps your innodb 
tablespace was corrupted somehow.
