A follow-up to Snap is unusable due to bad permissions - #22 by mr_cal.
Here’s my snapcraft.yaml, and I’m seriously out of options here 
I’ve downgraded to core20 and gnome-3-38 because gnome extension causes a segfault.
The build gives me an error:

As far as I know, pkg_resources is a part of setuptools. My YAML file explicitly mentions python3-setuptools, but it’s somehow not found.
Please advice.
