andy-testsnap-py

Example of a Python 3.6 snap using wxPython 4.0.4 built using the 'core18'
technique, which builds via a multipass virtual machine and core18 image.

This example is different to v_0.5.1 in that the #after: [desktop-gtk3]
line has been commented out and replaced with the entire desktop-gtk3:
part. This is because snaps built with core18 cannot refer to remote parts
thus parts must be explicitly listed.

To build this snap:
snapcraft
If you get trouble
snapcraft clean

Tip: since specifying parts or a step name is not yet supported (as of March 2019) these won't work:
snapcraft clean andy-testsnap-py -s pull
snapcraft clean andy-testsnap-py

Install the snap locally
sudo snap install --devmode --dangerous *.snap
snap list

Run
andy-testsnap-py -h

Ignore the warnings Gtk-Message: Failed to load module "canberra-gtk-module"
as these seem to happen to all snaps?

Publish
snapcraft login (use ubuntu one auth)
snapcraft register andy-testsnap-py
snapcraft push --release=edge *.snap
