sudo apt-get remove --purge mysql-server mysql-client mysql-common -y
sudo apt-get autoremove -y
sudo apt-get autoclean
sudo rm -rf /etc/mysql
sudo rm -rf /etc/mysql /var/lib/mysql
apt-get --purge remove "mysql*"
This helped me.

I had many issues with MySQL software, even after uninstalling the files ten times, I still have it in my machine.
I want to remove everything because I have issues when I re-installing it.
The picture below is a screenshot after uninstalling all the MySQL packages.
I tried these commands :
sudo apt remove --purge mysql-server
sudo apt purge mysql-server
sudo apt autoremove

sudo apt autoremove --purge mysql\* mariadb\*
sudo apt clean
sudo mv /var/lib/mysql /var/lib/mysql_bak

Done.

If your case is just forgot password see then doc here .
Or remove mysql then reinstall may solve your problem.
Remove mysql:
sudo apt-get remove --purge mysql-server mysql-client mysql-common
sudo apt-get autoremove
sudo apt-get autoclean
Reinstall:
sudo apt-get update
sudo apt-get install mysql-server
sudo mysql_install_db
sudo /usr/bin/mysql_secure_installation
And just check your disk isn't full.
I was trying to install mysql in ubuntu. I applied following command for it
sudo apt-get install mysql-server-5.5
But got the following error.
Errors were encountered while processing:
/var/cache/apt/archives/mysql-server-5.5_5.5.41-0ubuntu0.14.04.1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)
Please help me to solve the error.
Doing this solved it for me:
sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-5.5 mysql-server-core-5.5
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get install mysql-server
seems like there's an error with one of the packages being installed or that quite never installed properly in the past.
