Apt removes packages when trying to install 32bit version of existing library

Specifically I am trying to install libllvm10:i386 with libllvm10 already on my system. Apt now tries to remove practically everything important (xorg, xwayland, java, gnome, …). I am 99% sure this only happened after upgrading to Ubuntu 20.04 from 18.04, since steam is now trying to install this library and I had steam running before […]
