Tried removing mysql-server and mysql-server-5.7, same error.
Also purging causes the same error
you may try to remove package manually
su -c 'dpkg - P -remove --force-all mysql*'
then you need to rebuild rum database
su -c 'apt-get clean all && rpm --rebuilddb'
su -c 'package-cleanup --problems'
Edit
to backup all your databases
mysqldump -u USER -p --all-databases > /mnt/backups/all_databases.sql

A mysql client is installed, but when I try to launch it I get this:

Any help will be appreciated.
Well, I got no help from StackExchange, so I dug deeper and figured it out myself: First I got rid of mysql-server and mysql-client by following instructions at Removing MySQL 5.5 Completely. Then I simply installed the server and client as usual with apt-get. Everything worked fine after that.
