problems upgrading to mysql 5.5.33 on debian wheezy 1

I had a few problems with the update of the MySQL server from 5.5.31 to 5.5.33.

apt-get upgrade only led to
Error: Sub-process /usr/bin/dpkg returned an error code (1).

For me it has helped to enter the full path for log-bin in /etc/mysql/my.cnf and .to set innodb_data_home_dir.

I changed

log-bin = mysql-bin

to

log-bin = /var/lib/mysql/mysql-bin

and set innodb_data_home_dir:

innodb_data_home_dir = /var/lib/mysql

Next, the init script /etc/init.d/mysql had to be modified: put exit 0 before the first command in the start-case. The reason for this is to run the start block of the script successfully. In this case, although nothing happens, but it looks like there’s all the best. 😉

After that apt-get upgrade ran without problems.

Finally exit 0 has to be deleted from /etc/init.d/mysqld and the new mysql-server could be started by /etc/init.d/mysql start.
