'Mariadb can't be installed on Debian Buster, : post-installation script subprocess returned error exit status 134

I am trying to install Mariadb on Debian but I am getting the error below when I try to install it.

Mariadb was actually working for me for a while. I just tried to reinstall it because it was having hard time with starting (probably broke after apt upgrade). So I removed it and tried to reinstall it.

4.19.0-2-amd64 #1 SMP Debian 4.19.16-1 (2019-01-17) x86_64 GNU/Linux

This usually happens when you didn't remove mysql completely before trying to use mariadb or in your case you did not remove the mariadb package completely So try this.

sudo apt remove --purge mysql*
sudo apt remove --purge mysql
sudo apt remove --purge mariadb
sudo apt remove --purge mariadb*
sudo apt --purge remove mariadb-server

Then try re installing it again

sudo apt install mariadb-server mariadb-client
