I've tried many solutions but none of them worked. If I try to install any app like steam I get this:

problems, you have held broken packages.
Solution 1:
You have to fix broken repositories first by executing the following commands:
sudo add-apt-repository -r ppa:mc3man/xerus-media
sudo rm /etc/apt/sources.list.d/home\:strycore*.list
Then update package lists and install all needed upgrades by
sudo apt-get update
sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get dist-upgrade
