Bug Description

devstack installs python-cloudfiles, but that package's errors module (aliased in devstack as "swiftclient") seems to be missing the Error class. The latest source on github has the Error class.

Here's the error which causes devstack.sh to fail:

Using /usr/lib/python2.7/dist-packages
Finished processing dependencies for python-keystoneclient==2012.1

+ sudo python setup.py develop

Perhaps devstack should git clone this instead of using the package?

Duncan, I haven't seen this problem, even before horizon's recent rearrangement. If you can still duplicate it can you send the output of devsstack's tools/info.sh?

I was just able to reproduce this when re-stacking an older 11.10 install with a fresh copy of devstack. Despite the fact that 11.10 is supposed to have python-cloudfiles 1.7.9.2 packaged in apt, somehow version 1.7.9.1 was installed. As best I can tell this problem isn't entirely new (as the cloudfiles dependency was moved from pip to apt-get a few months ago) but may have been previously masked by other poor import exception handling which was recently cleaned up in Horizon.

It doesn't seem to affect everyone, however. As a precautionary measure we could move python-cloudfiles back to being installed by pip instead of apt just to be certain this problem doesn't bite anyone else...

    Moves python-cloudfiles dependency back to PIP.

    For reasons currently unknown, apt-get seems to install
    an unusably old version of python-cloudfiles in some
    small subset of cases. To avoid that frustration for the
    users it does affect, this patch moves python-cloudfiles
    back to being installed by pip instead.

    Fixes bug 931269.
