Problem

Hi, my problem is that today I did the uninstallation of mysql with this comand:

sudo apt-get remove --purge mysql*
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get remove dbconfig-mysql
sudo apt-get dist-upgrade

but then I tried to reinstate it with the following commands:

sudo apt-get update
sudo apt-get install mysql-server
mysql_secure_installation

but when I launch mysql_secure_installation, he asks me for the password I do not have. and so I'm stuck

Questions:

How can I completely uninstall mysql?

How can I overcome this password problem?

I conclude by saying that I really hope to be able to re-use MySQL on my PC, thanks for the help.

Important: I am not a native English speaker, so for any problem of
understanding let me know, thanks.

The mysql configuration datadir defines where the databases are kept. Normally it is /var/lib/mysql, inside there will most likely be the databases from the previous install.

The databases are saved as $datadir/$DATABASE. The MySQL passwords are kept in the mysql database in the user table. Save what you need and remove the entire datadir directory then try to install mysql-server again.
