We have identified a number of electron-based desktop applications which already have builds for Linux, but are not yet easily available in Ubuntu. The goal of this task it to select one of those applications and update the build system to add snap support.

Preparation:

Many of these applications require a newer version of node/npm to build than is available in Ubuntu. We recommend using Ubuntu 16.04 machine, virtual machine or container. Please do not do this task on a 17.10 system, but use 16.04.

In that 16.04 system, install node/npm from upstream nodesource as detailed at https://github.com/nodesource/distributions#debinstall

You may also want to go through the electron guide, to ensure your system is configured correctly to build electron applications successfully. https://docs.snapcraft.io/build-snaps/electron

I've put together this pull request to add a snap package. I've tested it on Ubuntu 16.04, but it should work just as well on Ubuntu 14.04, Linux Mint, Manjaro, Debian, OpenSUSE, Solus, etc.

If you merge and npm COMMAND on an Ubuntu 16.04 VM with an appropriate version of node installed it will create dist/NAME_VERSION_amd64.snap.

Copy this to a Linux system, enable snap support, then run: sudo snap install --dangerous NAME_VERSION_amd64.snap. Execute it with NAME from the terminal or find it in the desktop launcher.

If you create a developer account and push this to the Snap Store, it can be discovered and installed through GNOME Software and https://snapcraft.io/discover. To create the developer account, sign up here, then register the "NAME" name.

You'll need the snapcraft comm

Steps to setup easy-openvpn on Ubuntu Core

This gist is to accompany a more wordy blog post which covers everything in much more detail. These are the easily copy/pastable steps.

For this you will need:-

Raspberry Pi 2 or 3, PSU, keyboard, LAN connection, HDMI cable and display
Laptop/desktop computer - mine is running Ubuntu 18.04 but anything with SSH will do
Micro SD card and adapter to attach to the computer
