As a followup to my thread on devel@ and test@ list with the subject "Undefined %epoch problem (Re: rawhide report: 20150730 changes)", Yum utils repoclosure has been confirmed as being the culprit, since it is still the tool that mash's spam-o-matic script relies on. (!) Important: There is a fixed "blktap" build in updates-testing, so the problem is only reproducible as long as that fix is not pushed into "updates". In that case, it will be necessary to create a dummy broken package to include an undefined %epoch macro in a dependency again. So, watch this (Fedora 22 x86_64): # repoclosure Yum-utils package has been deprecated, use dnf instead. See 'man yum2dnf' for more information. Reading in repository metadata - please wait....

You probably have corrupted RPMDB, running 'rpm --rebuilddb' might fix the issue. The downloaded packages were saved in cache till the next successful transaction. You can remove cached packages by executing 'dnf clean packages'
Yum backend is affected, too: # rpm -qf /usr/bin/yum-deprecated yum-3.4.3-505.fc22.noarch # yum-deprecated install blktap-devel Yum command has been deprecated, use dnf instead.

Followup to devel@ list. It's createrepo (and createrepo_c) that only understand numbers as Epochs due to relying on strtol() as parser. Any non-number, such as an undefined macro or a typo, results in a default Epoch 0 in the repodata.
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates.
