I have a feeling this has to do with electron-builder expecting a newer version of snapcraft than what I can wrangle onto Travis CI. Is this a no go due to the age of the distros that Travis CI supports? Could anyone recommend using an older version of electron-builder instead or a way to get a newer version of snapcraft onto Travis CI? The build works fine on my dev machine running Ubuntu 16.04.

snapcraft : 1.1.0

2.x is required.

Please use Docker if you don't want to configure all this hell.

[chgibb]

@develar thank you for the quick response. This does not exactly answer any of my questions however.

From the wiki: https://github.com/electron-userland/electron-builder/wiki/Multi-Platform-Build

Travis Linux

Trusty is required — default Travis Linux dist is outdated and icnsutils version is non-functional.

sudo: required
dist: trusty

This would suggest to me that my Travis config is correct.

As for your recommendation about Docker, how would I obtain a Docker image for electron-builder?

[develar]

how would I obtain a Docker image for electron-builder?

We provide prebuilt docker images — https://github.com/electron-userland/electron-builder/wiki/Docker — electronuserland/electron-builder:latest

I cannot provide you example for Travis, but for CircleCI — https://github.com/electron-userland/electron-builder/blob/master/circle.yml Anyway, should be easy, please see https://docs.travis-ci.com/user/docker/

This would suggest to me that my Travis config is correct.

I will fix docs.

Thanks!
