if i install libncurses 5 (from https://aur.archlinux.org/packages/ncurses5-compat-libs/), there's only this error left:

the demos run though :-)

There appears to be a general problem with library search paths. You can temporarily try working around it by preloading the mono library:

$ (export LD_PRELOAD=/opt/Unity-2018.2.2f1/Editor/Data/MonoBleedingEdge/MonoEmbedRuntime/libmonobdwgc-2.0.so ; /opt/Unity-2018.2.2f1/Editor/Unity)

Hi! I'm curious if you ultimately resolved this issue. FWIW the only distribution of Linux we "officially" support is Ubuntu. That said, if you run into other issues, the best place to get help is probably the Unity Linux forum.
