For apt.mopidy.com, none of this is an issue.
For Ubuntu:
- none of this is an issue in 15.10 or 16.04 LTS.
- 15.04 is soon out of support.
- 14.04 LTS is old enough that you'll have to read older docs to expect
facts matching your installation.
For Debian:
- none of this is an issue in sid or stretch.
- Jessie this might be an issue, but the same sentiment as for Ubuntu
14.04 LTS applies.
Fixes#1399
