[Merge] ~cjwatson/launchpad:usr-bin-python2 into launchpad:master

To: mp+381996@xxxxxxxxxxxxxxxxxx
From: Colin Watson <cjwatson@xxxxxxxxxxxxx>
Date: Thu, 09 Apr 2020 11:28:28 -0000
Reply-to: mp+381996@xxxxxxxxxxxxxxxxxx
Sender: bounces@xxxxxxxxxxxxx

Colin Watson has proposed merging ~cjwatson/launchpad:usr-bin-python2 into launchpad:master.

Commit message:
Use /usr/bin/python2 rather than /usr/bin/python

Requested reviews:
  Launchpad code reviewers (launchpad-reviewers)

For more details, see:
https://code.launchpad.net/~cjwatson/launchpad/+git/launchpad/+merge/381996

This ensures correct behaviour on systems where /usr/bin/python is Python 3 (e.g. Ubuntu focal with the python-is-python3 package installed), until such time as we finish porting to Python 3.

I've checked that xenial has /usr/bin/python2 in python-minimal.
-- 
Your team Launchpad code reviewers is requested to review the proposed merge of ~cjwatson/launchpad:usr-bin-python2 into launchpad:master.
