Comment 3 for bug 1543243

Tested in an up-to-date xenial:

- update to snapcraft 2.12
- get a snap that uses subversion as the source. (Thanks to popey, I just had to modify the source of his dosbox)
- snapcraft
- the snap is generated
- sudo snap install
- the snap is installed
- dosbox
- the snap starts

I'm marking this as verified.

Thanks Steve!
