Answer 1

My answer from askubuntu.

None of the apt methods worked for me, try this:

Find locking process

$ ps -eaf
root      7316     1  0 00:19 ?        00:00:00 /usr/bin/dpkg --status-fd 35 --configure --pending
root      7808  7316  0 00:19 ?        00:00:00 /usr/bin/perl -w /usr/share/debconf/frontend /var/lib/dpkg/info/mysql-se
root      7817  7808  0 00:19 ?        00:00:00 /bin/bash /var/lib/dpkg/info/mysql-server-5.7.postinst configure
mysql     7973  7817  0 00:20 ?        00:00:00 mysqld --user=mysql --init-file=/var/lib/mysql-files/tmp.iNyY06ty0K --so

Kill it

do sudo kill -9 7973, basically the mysql one.

Now purge

sudo apt-get purge mysql-server-5.7 # Or whatever you are trying to purge.
