Pecan version issue in Icehouse ceilometer package

[Michael Tughan]

I installed ceilometer from the Icehouse packages on Ubuntu 14.04 earlier today and ran into a VersionConflict python error, where ceilometer requires pecan >= 0.4.5, but pecan 0.3.0 is available.

Traceback (most recent call last):

According to a few people in #ubuntu-server, this looks to be a packaging issue with the requirements.txt in ceilometer.

Another report is at: https://ask.openstack.org/en/question/27951/pecan-version-for-ceilometer-in-icehouse-swift-proxy/

Sorry, forgot to give that link before. Yes, a Google search turned that up first, which is when I asked about it in #ubuntu-server on freenode. Manually modifying requires.txt to "pecan>=0.3.0" also gives me the same happybase error he mentioned in the comments. Whether that should be a separate bug or not, I'm not sure.

Same problem here. Please place the appropriate version packages in the icehouse repo ASAP.

Why was this not caught by testing/QA? Is metering swift with ceilometer considered an edge case?

I believe that this was fixed under bug 1317147
