Simple scan snap isn't starting on Ubuntu 18.04
I have simple scan 3.28.1 installed on Ubuntu 18.04.1 (as well as xsane (?) and HPLIP, which together allow me to scan via wireless). When starting simple scan from the terminal, I don't see any errors/messages. I see the programme and a loader spinning icon in the top, but after a while it just disappears and nothing happens.
