Debian 10 - Broken MariaDB update - system upgrade problems

My system has a broken MariaDb update going from 10.3 to 10.4. MariaDb does still work fine, but now I am having system upgrade issues. I have tried looking online for solutions but can't seem to find anything. Problem:

-shellsession
$ sudo apt-get upgrade

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
  mariadb-server-10.3 : Depends: mariadb-client-10.3 (>= 1:10.3.28+maria~buster) but 1:10.3.27-0+deb10u1 is installed
  mariadb-server-core-10.3 : Breaks: mariadb-client-10.3 (< 1:10.3.28+maria~buster) but 1:10.3.27-0+deb10u1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

While I try to fix-broken :

-shellsession
$ sudo apt --fix-broken install
