Comment 1 for bug 1401323

The trusty version of this charm is also failing automated testing.

The latest results for the trusty squid-reverseproxy charm:

http://reports.vapour.ws/charm-tests/charm-bundle-test-10320-results

It looks like the error is different than the precise version, these results indicate the `make test` target is failing with:

ERROR: Failure: ImportError (No module named apt_pkg)

Please investigate and fix the charm or the tests so the squid-reverseproxy charm passes automated testing.
