I tried to purge all packages installed, related to mysql. And this:

apt-get purge mysql-server
apt-get purge mysql-common
rm -rf /var/log/mysql
rm -rf /var/log/mysql.*
rm -rf /var/lib/mysql
rm -rf /etc/mysql
# and then:
apt-get install mysql-server --fix-missing --fix-broken

But even after it I cannot install mysql.

Any suggestions?
