    Building off of another answer, open a terminal (press Ctrl+Alt+T) and run the following:

    sudo -i
service mysql stop
killall -KILL mysql mysqld_safe mysqld
apt-get --yes purge mysql-server mysql-client
apt-get --yes autoremove --purge
apt-get autoclean
deluser --remove-home mysql
delgroup mysql
rm -rf /etc/apparmor.d/abstractions/mysql /etc/apparmor.d/cache/usr.sbin.mysqld /etc/mysql /var/lib/mysql /var/log/mysql* /var/log/upstart/mysql.log* /var/run/mysqld
updatedb
exit

    If you want to delete the log of what you did while using the mysql client:

    rm ~/.mysql_history

    If you want to delete the logs of what all users on the system did while using the mysql client (the other users might be unhappy with this):

    awk -F : '{ print($6 "/.mysql_history"); }' /etc/passwd | xargs -r -d '\n' -- sudo rm -f --

    or for all logs including those outside of existing user home directories:

    sudo find / -name .mysql_history -delete

  2. I found some help, but it did not remove everything. I added an asterisk before and after mysql like this:

    sudo apt-get remove --purge *mysql\*
sudo apt-get autoremove
sudo apt-get autoclean

  3. Another way, that worked for me, was to use Synamptic Package Manager. On the left hand pane,where it says: All, Installed, etc. there is an entry for Not Installed (residual config.) (or similar wording). Under there I found options to clear all MySQL install files. This worked for MySQL 5.7.

  4. I used a collab of 2 answers, first I ran this

    • sudo -i

    • service mysql stop

    • killall -KILL mysql mysqld_safe mysqld apt-get --yes purge mysql-server mysql-client

    • apt-get --yes autoremove --purge

    • apt-get autoclean

    • deluser --remove-home mysql

    • delgroup mysql

    • rm -rf /etc/apparmor.d/abstractions/mysql /etc/apparmor.d/cache/usr.sbin.mysqld /etc/mysql /var/lib/mysql /var/log/mysql* /var/log/upstart/mysql.log* /var/run/mysqld

    • updatedb

    • exit

    Then checked, but still had an error, so as backup, I ran this within the terminal.

    • sudo apt-get remove --purge *mysql*
    • sudo apt-get autoremove
    • sudo apt-get autoclean

    Worked perfectly.
