Thanks! I was not able to get this to work:
qvm-run fedora-appvm qubes.StartApp+firefox
However I found this, and it does work for most apps:
qvm-run -q fedora-appvm firefox
Based on the discussion about it here it’s unclear to me if I should keep using it long term:
Apps I have installed myself though I’m not able to get working so far. I think the problem is I don’t know what the your-app is called. I’m not even seeing them in /usr/bin under any names I recognize.
Anyone have ideas on where to find that info?
