Comment 1 Sofer Athlan-Guyot 2017-01-10 14:50:49 UTC
Hi,

Puppet is upgraded to version >4.  It now includes its own rgen lib.
But there is some package leftover on rhel plateform that breaks
puppet, namely ruby-rgen-0.6.5-2.el7sat.noarch.

You have to run this before the undercloud upgrade for puppet to continue
to work.

    sudo rpm -e --nodeps ruby-rgen-0.6.5-2.el7sat.noarch

Not sure what is the best course of action here.  Do we :

 - improve packaging to make sure this one is absent (or conflict);
 - integrate it in python-tripleoclient;
 - do a documentation resolution;

Comment 2 Sofer Athlan-Guyot 2017-01-10 15:08:50 UTC
It looks like the best course of action is to add the 

Obsoletes: ruby-rgen 

in the puppet spec file.  Courtesy of mburns.

Waiting for a package to test.

Comment 6 Lon Hohberger 2017-01-10 22:28:04 UTC
Yes, obsoletes is fine here.  The 'ruby-rgen' package appears to have been built specifically for puppet a few years ago, and sort of does a strange unpack/repack of the rgen gem.

Thus, Obsoletes: should be fine.  rubygem-rgen should be used by other apps (if needed).

Comment 10 Sofer Athlan-Guyot 2017-03-22 09:48:21 UTC
Hi,

so could we have the package here, so that we can exclude the issue from what edannon is seeing ?

Adjusting the status.

Thanks.
