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

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor.
Tumbleweed:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy
Leap 15.x:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy
If needed, Swap out openSUSE_Leap_15. for, openSUSE_Leap_16.0 if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install andy-testsnap-py, simply use the following command:
sudo snap install andy-testsnap-py --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
