Cant upgrade MariaDB 10.3 on Ubuntu 19.10 anymore (Unmet dependencies)

Hi

I wanted to update my Ubuntu 19.10 to 20.04 today and got the message that i have to install all updates before. Tried apt-get update && apt-get upgrade to update everything and saw, that i cant update because of mariadb.

I get the following error, which blocks any install or update.

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 (>= 1:10.3.23+mariabionic) but 1:10.3.22-0ubuntu0.19.10.1 is to be installed mariadb-server-core-10.3 : Breaks: mariadb-client-10.3 (< 1:10.3.23+mariabionic) but 1:10.3.22-0ubuntu0.19.10.1 is to be installed E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I tried to fix it for a while, then i tried to remove mariadb to make a clean install, but i cant remove mariadb complety. Hopefuly anyone here can help my fix my problem.

Greetings

After some more Hours i found a solution.

I had some PPA listed in /etc/apt/sources.list.d/* which were in conflict with the normal reposatory.

i deleted them, cleaned my package database with "sudo apt-get autoclean", then used "sudo apt-get -f install" to fix the install.

Then i upgraded succesfully to Ubuntu 20.04 and hopefully will soon fix my nextcloud install again.

The Thread can be closed. :)
