You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

You have qpid-proton-c 0.14 installed from the CentOS extras repo. You're trying to install a package from EPEL that requires a newer version of that qpid-proton-c package that is also in EPEL. I suspect that you have configured yum-plugin-priorities to prefer extras over EPEL so it will not find the newer copy that is in EPEL (because you told it not to).

You either need to adjust your priorities to make EPEL more important (probably not the best solution) or you need to add exclude=qpid-proton-c (or perhaps better since there are other qpid packages in extras, use exclude=qpid*) to the /etc/yum.repos.d/CentOS-Base.repo in the [extras] section.

Thank you very much adding the exclude line solved the problem.
