I know there are many questions regarding mysql not starting. I've tried following things
Checking MySQL error log —
error reading '/var/log/mysql': Is a directory
/var/log/dist-upgrade/apt.log file for broken packages again no such file or directory
Remove MySQL-server and reinstall it But it's not getting uninstalled at all
this problem occurred when I uninstalled "plasma-desktop". I used following commands to remove "plasma-desktop" and related packages.
sudo apt-get purge '^kde' '^kubuntu' '^plasma' sudo apt-get remove plasma-desktop sudo apt-get autoremove
There was no error produced by the above three commands.
