Viewing post in Itch app won't start on Ubuntu 18.04
I've identified the issue here: https://github.com/itchio/itch-setup/issues/4
I'm working on a fix, I'll let you know when it's out!
The fix is out, if you download & run the installer from https://itch.io/app you should have a working (and self-updating) install of itch.
