Issue body
I run a wily kernel on a vivid system. I tried to use snapcraft with the following procedure:
$ cd /tmp
$ bzr branch lp:ufw
...
$ cd ./ufw
$ cat > snapcraft.yaml <<EOM
name: ufw
version: 0.35~-1

summary: program for managing a Netfilter firewall
description: Uncomplicated FireWall is a front-end for iptables, to make managing a Netfilter firewall easier. It provides a command line interface with syntax similar to OpenBSD's Packet Filter. It is particularly well-suited as a host-based firewall.

TypeError: argument 2 must be str, not None
[1]
Turned out to be <Version: package:'linux-libc-dev' version:'4.0.0-4.6'> was the problem. 3.19.0-28.30 is the only available version on my system. Two things:
1. snapcraft should use its own sources.list and cache to avoid this sort of thing
2. the error output didn't indicate the progress well enough for me to know what the problem was (from the above, it looked like libssl1.0.0 was the issue, but it wasn't)
