[Bug]: lutris install no longer works

[h4de5]

Describe the Bug

when installing lutris and restarting the container, the following error appears in the logs.

The following packages have unmet dependencies:
 lutris : Depends: gir1.2-webkit2-4.1 but it is not installable
          Recommends: python3-evdev but it is not going to be installed
          Recommends: gvfs-backends
          Recommends: libwine-development but it is not installable
          Recommends: winetricks but it is not going to be installed

I also found that work around online:
https://www.reddit.com/r/linuxquestions/comments/zatlba/comment/izgxmzc/?utm_source=reddit&utm_medium=web2x&context=3

doing this (by removing the part from the /home/default/init.d/install_lutris.sh), lutris did install and I was able to run it.

echo "deb http://download.opensuse.org/repositories/home:/strycore/Debian_10/ ./" | tee /etc/apt/sources.list.d/lutris.list 

Steps to Reproduce

1. connect to the x desktop of steam-headless container using vnc
2. click on install lutris from the menü
3. restart container
4. show docker log from starting container
5. lutris is not installed in the container

Expected Behavior

lutris should be available after the documented steps

Lutris should now be installed from the "Software" app in the menu. This will install the Flatpak.
