# Install Core Keeper server dependencies and clean up
# libx32gcc-s1 lib32gcc-s1 build-essential <- fixes tile generation bug (obsidian wall around spawn) without graphic cards mounted to server
# need all 3 + dpkg i do not know why but every other combination would run the server at an extreme speed - that combination worked for me.
