I am running MariaDB 10.3 on Ubuntu 20.04. Now MariaDB is not running and one database in it. Can I uninstall the MariaDB 10.3 retaining database? My plan is that install a higher version of MariaDB and get back the existing database. If so, which commands do I have to apply?

I got the solution, uninstall MariaDB without deleting databases and reinstall it again.

sudo apt purge "mariadb*" -y sudo apt autoremove -y sudo apt-get install mariadb-server mariadb-client
