mongodb charm does not deploy on Xenial

[Chris Glass]

The mongodb charm (cs:trusty/mongodb) does not install successfully on xenial, since Xenial does not offer python2 out of the box and the charm logic is written in python 2 (relying on "/usr/bin/env python", and that fails on Xenial).

I have tested deploying cs:trusty/mongodb on xenial machine (I first juju deployed cs:xenial/ubuntu, branched cs:trusty/mongodb locally, and then deployed branched charm from 'local' repository). It works fine (haven't run into dependencies issue) unless you want replicaset to be formed. That fails, due to this bug: http://pad.lv/1513094

I am working on a fix for that.

Additional comment here for things that don't just work in Xenial - the nrpe check (hooks/hooks.py, line 1426) hardcodes the check command as check_cmd='check_upstart_job mongodb',

check_upstart_job, of course, doesn't work in Xenial because it's systemd.

Hi, Xav.

Yup, unfortunately this is true. I'll be removing the current check for upstart job and add mongo nrpe check which will work on both init/upstart and systemd systems.

MongoDB is not available on s390x from the archives, additional PPA needs to be enabled.
