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.

  • Thanks for your assistance. Here is the result of your suggestion, after touching /etc/mysql/my.cnf.fallback sudo dpkg-reconfigure mysql-common /usr/sbin/dpkg-reconfigure: mysql-common is broken or not fully installed

  • This page askubuntu.com/editing-help#comment-formatting explains how to format comments, however, the suggestion to add to two spaces for a line break does not work. Are linebreaks not allowed in comments despite the advise from stackexchange stating in the markdown editing help age to add 2 spaces for a line break?

Solved:

There were two architecture libraries on my system for mysql.

libmysqlclient20:amd64 libmysqlclient20:i386

I removed the i386 and all is solved.
