Yes on the 'cd testing', we'd need to document that. But that's not really the problem. OK, so we have some answer variability here: On Ubuntu 14.04.4: - ./run-tests succeeds - testing/run-tests succeeds On Mac OS X 10.11.3: - ./run-tests fails - testing/run-tests succeeds On your system (what?): - ./run-tests fails - testing/run-tests fails The only difference I can see is that the first two tests start with py26 and the last with py27, but if I modify run-tests to run 'tox -e py27', I get the same results. It has to be in the environment somewhere. Bazaar (bzr) 2.7.0dev1 Python 2.7.6 Try this: bzr export duplicity-0.7.06.tar.gz from latest_duplicity/ On Sun, Feb 28, 2016 at 5:16 AM, Aaron Whitehouse <
