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?
Enable snaps on Pop!_OS and install andy-testsnap-py
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.
Enable snapd
Snap can be installed on Pop!_OS from the command line. Open Terminal from the Applications launcher and type the following:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
Install andy-testsnap-py
To install andy-testsnap-py, simply use the following command:
