All solutions listed here for removing MySQL fails:

Uninstall MySQL from Ubuntu 16.04

and

Removing MariaDB Installs MySQL and vice-versa

These are my errors:

  1. It looks like there is an error while configuring mysql-common, and that causes a dependency problem that results in mysql-client-5.7 failing to be removed.

    The configuration error is error: alternative path /etc/mysql/my.cnf.fallback doesn't exist, so naturally i'd try to create that path by running sudo touch /etc/mysql/my.cnf.fallback

    After that running sudo dpkg-reconfigure mysql-common will reveal if the error is resolved, if it is, you can likely remove mysql now using sudo apt-get purge mysql*

    If this did not help, please provide the output/errors of these commands so that me and others can determine the problem further.

  2. Solved:

    There were two architecture libraries on my system for mysql.

    libmysqlclient20:amd64 libmysqlclient20:i386

    I removed the i386 and all is solved.
