charm promulgate fails with lazr.restfulclient (0.13.4)

[Kevin W Monroe]

I ran into the following on a Vivid vagrant image:

$ juju charm promulgate -s trusty -v
INFO:Running charm proof ...
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/charmtools/proof.py", line 23, in <module>
    from charms import Charm
  File "/usr/lib/python2.7/dist-packages/charmtools/charms.py", line 12, in <module>
    from launchpadlib.launchpad import Launchpad
  File "/usr/lib/python2.7/dist-packages/launchpadlib/launchpad.py", line 33, in <module>
    from lazr.restfulclient.resource import (
ImportError: No module named restfulclient.resource

Relevant packages:
ii charm-tools 1.6.1-0ubuntu2~ubuntu15 all Tools for maintaining Juju charms
ii python-lazr.restfulclient 0.13.4-4 all client for lazr.restful-based web services

To work around this, I downgraded lazr.restfulclient as follows:

$ sudo pip install --upgrade lazr.restfulclient==0.13.1

After this, I was able to successfully run charm promulgate.

This is bubbling up from charm-tools calling

launchpadlib.launchpad import Launchpad

Which seems to indicate an issue with the Launchpad library/lazr.restfulclient

I found that a rogue pip installed lazr.authentication was causing my problem:

With that installed, "from launchpadlib.launchpad import Launchpad" fails. With it uninstalled, the import succeeds. I'm ok with closing this bug as it's my own fault for mixing pip + apt for python mods, unless someone wants to sort this out any farther.

I've also got an strace of the failed charm promulgate.. i'll leave it here for posterity:
