Unable to unstall openshift

[Martin Mágr]

I'm trying to deploy OpenShift on three nodes via TripleO and am currently on packaging conflict on master and worker nodes:

I'm seeing the same thing installing tripleoclient via quickstart so I suspect some repo conflict is causing this

[Steven Hardy (shardy)]

python-docker-py-1:1.10.6-7.el7.noarch seems to be pulled in from centos extras - disabling that repo on my virthost seems to have resolved the issue, Martin can you confirm if that also resolves your problem?

[Steven Hardy (shardy)]

Hmm actually -extras is also defined in tripleo-quickstart (config/release/tripleo-ci/CentOS-7/master.yml if you're using the tripleo-ci master release) so we may need to remove that?

[Steven Hardy (shardy)]

Ok after disabling -extras it then fails installing skopeo so it seems like there is more than one repo config, probably we need to confirm if --release master-tripleo-ci is still tested in CI or if that should now be removed

[Steven Hardy (shardy)]

So after some discussion on IRC (thanks marios & ykarel!) it seems this is a duplicate of https://bugs.launchpad.net/tripleo/+bug/1806853, which was fixed by https://review.rdoproject.org/r/#/c/17746/3/deps.yml

So it seems we both have some stale repo config such that we're getting the old version of python-docker?

[Steven Hardy (shardy)]

Ok so the fix in my case was to rm -fr /var/cache/tripleo-quickstart, the cached images were stale.

Martin can you confirm if the same fix works for you?

[Juan Antonio Osorio Robles (juan-osorio-robles)]

Is this still an issue?

[Martin Mágr (mmagr)]

Closing this really old bug.
