dependency conflict error HDP 3.0 upgrade: freeipa

[#1]

I am attempting to upgrade from HDP 2.6 to 3.0 and am encountering dependency conflicts related to freeipa on CentOS 7. Has anyone else encountered this? From a quick google search, the freeipa/ipa conflict is a known bug that can be ignored, but I am unsure of how to get Ambari to do so...or if that is a good idea:

As it were, being in a walled off environment that does not have the latest version of the CentOS repos, this was a significantly more head-scratching affair. As it turns out, the simple fix is to update yum, which fixes this bug. Unfortunately, that was not an option for me. Fortunately, there is a manual work-around that did work: Comment 17, which is to o the following:

sed -i "/for creq in pkg.conflicts:/a\ if creq[0].startswith('freeipa'): continue" /usr/lib/python2.7/site-packages/yum/rpmsack.py

So, in case someone else runs into this issue and is in the same type of restricted environment that I am in, this should fix things for you too...
