You are correct, but what "more info" do you want?
Well, a list of names of those conflicting packages would be nice to have. Or instructions how to ask yum to compile it.
You've spelled it out quite well, you have the solution (set the lowest prio == highest value for epel), end of story?
Unfortunately, it isn't. I was running the machine for some time without having the yum-priorities plugin. I (naively) believed that EPEL is careful not to create conflicts against base (I have read on this very list that it's safe to use). Stuff got installed, updated several times over, etc.
Now after I figured there are in fact conflicts, I need to figure out the consistency of the software installed on my machine. How many (and which) packages from base have been stepped over by epel on my system? How severe are the consequences?
I need to know how affected my system is, which packages to reinstall (now that I've activated priorities), etc. It's a mess that needs to be cleaned up.
If you want it fixed you should report this to EPEL, not here. But with a large repo like EPEL this is bound to happen again and again as the distrib is a moving target. yum priorities mostly solves it.
No, I don't really care to have it fixed, yum-priorities can take care of that in the future. But I want to fix my server, to make sure that all packages from base are still there.
And I also want to make some noise about it on this list, so that other people don't end up with the same problem. It should be stated clearly that epel is *not* safe to use without the priorities plugin.
To be perfectly honest, the differences between EPEL and Base+extras can usually be completely ignored anyway.
While somethings may be in epel and extras .. and the extras versions might lag, the extras version likely came from EPEL in the first place and was added as a build requirement for some other package in extras.
This means that if there is a newer version in EPEL later, it is likely not going to cause a problem if it is installed on CentOS .. and in reality, we should probably be pulling that newer EPEL package into extras anyway.
I don't think, if you stay in the elrepo, EPEL, and Base+Extras family that you are going to be hurt very often using whatever yum finds without yum-priorities at all. I would add the NUX repo to those as well. If you go outside those 4, maybe yum-priorities become more important.
I used to add RPMFUSION to that, but as of last time I looked, not more than 2-3 weeks ago, they still don't have EL7 listed.
