When I try to install mysql-server, an error comes like:
dpkg: error processing package mysql-server (--configure):
dependency problems - leaving unconfigure
i face same error due to problem in my upgrade from ubuntu 18.04 to ubuntu 20.04 , what i did is get mariadb instead also make sure when you do pruge mysql that if asked you to remove dbs in the dir tell it not to delete the dbs so you will have your old databases with no data loss
what i did was this cmds
sudo apt-get purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade
sudo apt-get install mariadb-server
