Title:
lxc scripts break when user has PYTHONPATH set
Status in pyjuju:
Fix Committed
Status in juju package in Ubuntu:
Fix Released
Status in lxc package in Ubuntu:
Invalid
Bug description:
The various lxc scripts installed in /usr/bin are Python 3 only. If
the user has PYTHONPATH or other similar environment variables set,
these scripts can incorrectly inherit details from the user's Python 2
setup when run.
This can result in either a crash as per the initial report, or a
traceback over syntax differences such as the following in juju:

WORKAROUND:
Add "-Es" to /usr/bin/lxc-ls (after /usr/bin/python3 ) so that those
environment variables are ignored.
