Installing Java doesn't work on newly installed Ubuntu 18.04

Installing Java fails with the following error:

This is what happens if I try to install it with sudo:

https://github.com/jacobzimmermann/omegat-cat-snap is based on Java8, maybe you could find some hitns there? I know how to build docker-images. But snap is very new for me.

See my comments in this issue: https://github.com/nsg/snap-minecraft/issues/2

Oh, I just noticed that the minecraft snap from snapcrafters has been removed. Leaving mine the only one left, with no options left I will consider fixing this.

Closing this old issue to clean up, it you haven't found it already I'm using mc-installer these days for my minecraft needs.
