testtools-1.7.0 triggering pkg_resources.VersionConflict: (unittest2 0.5.1 (/usr/lib/python2.7/dist-packages), Requirement.parse('unittest2>=1.0.0'))

pkg_resources.VersionConflict: (unittest2 0.5.1 (/usr/lib/python2.7/dist-packages), Requirement.parse('unittest2>=1.0.0'))

Looks like we install python-unittest2 0.5.1-1ubuntu1 from apt-get.

This is impacting stable/juno and stable/icehouse. Which means grenade on master is broken since we cannot install stable/juno

looks like uncapped transitive dependency

2015-03-10 21:59:48.127 | Collecting testtools (from zake>=0.1->tooz<=0.12,>=0.3->ceilometer==2014.2.3.dev2)

And ceilometer doesn't have testtools as a regular requirement so the cap sync stuff doesn't kick in.

Zake has been fixed so testtools won't be installed from there https://github.com/yahoo/Zake/blame/master/setup.py

    Stop installing unittest2 from deb packages

    The version installed is conflicting with the version required in
    testtools-1.7

    While a better solution is to dig through and figure out what is causing
    the transitive floating dependency that installs testtools 1.7
    this should fix the issue for stable/icehouse. And we need to fix
    stable/icehouse to fix stable/juno (because grenade) which in tern is
    needed to unbreak master branch.

    Stop installing unittest2 from deb packages

    The version installed is conflicting with the version required in
    testtools-1.7

    ceilometer installs tooz which installs zake which has a run time
    dependency on uncapped testtools. Which in turn requires a version of
    unittest2 that conflicts with the version provided via packages

    We need the fix to stable/juno to unbreak master because grenade.

    Don't use packaged unittest2

    Let pip install unittest2; pip installation can conflict with the
    packaged version.

    We should not need work-arounds for the installed broken version of
    unittest2 any more (even though this was only for python2.6, which I
    doubt anyone is actually using for devstack work anyway)
