Thanks for the report! I can't replicate on my working machine, will look into it :+1:

[xnox]

If that's of any help I can test build things. And you can always setup to build/package/publish your software as snap in snapstore; or create a PPA in launchpad.net both offer amd64, i386, armhf, arm64, ppc64el, s390x architectures (just enable them in settings). Can't get a console, but it can do builds for you.

hmmm, I haven't used launchpad, I'll look into it. In the meantime, I just pushed some big updates to master, if you're willing, pull them and run through the tests? I'm dropping python2 support soon, you might try the tests on both 2 and 3.

0.8.1 was just released if you're interested in testing...it will be the final py2.7 build
