Question using linux mint problem with package manager 2019

using linux mint problem with package manager 2019

i am trying to get a linux machine to check cross platform compatibility.

I have installed the hub and 2019.3.14 for linux.

The package manager is blank and bugged out,
i have to guess where the buttons are.

I have had to download githubs and copy them into project packages to get unity to see them.

The asset store seems to work okay.

Linux unity seems to have a big problem with mp4s. Especially 360 mp4s.

I am downloading avpro, hopefully that will help.

I am trying to get 360 mp4s to work on a skybox. It works on windows.

WHen i complie my basic 360 project on a windows machine and target a linux platform it creates something that does not run on linux mint 64.

I hope people can help

 

here is an example of the bug after i have imported and asset from the asset store.
Package manager started working now for some reason.
