The syslog reveals there is a problem with the init script:

I finally figured out the issue. Basically, the definition of

some parameters has been removed from the previous version of mysql

and has been replaced with different names. To fix, in

/etc/mysql/my.cnf, replace:

# Tom Added to ensure the server character set is set to utf8

default-character-set = utf8default-collation = utf8_general_ci

with:

# Tom Added to ensure the server character set is set to utf8

character_set_server = utf8

collation_server = utf8_general_ci

Or easily run:

# Miraz added dpkg-reconfigure

dpkg-reconfigure mysql-server-5.5

But make sure there's no old mysql version installation

installed, if there was please remove:

# Miraz quick mysql package check

dpkg -l *mysql*
