Description Michael Schwendt 2015-08-06 08:55:31 EDT
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.

Running transaction check
Error: transaction check vs depsolve:
blktap(x86-64) = %{epoch}:3.0.0-2.fc22.git0.9.2 is needed by blktap-devel-3.0.0-2.fc22.git0.9.2.x86_64
To diagnose the problem, try running: 'rpm -Va --nofiles --nodigest'.
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'
Comment 1 Michael Schwendt 2015-08-06 09:05:43 EDT
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.
See 'man dnf' and 'man yum2dnf' for more information.

Comment 2 Michael Schwendt 2015-08-06 12:46:04 EDT
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.
Comment 3 Fedora End Of Life 2016-07-19 13:23:39 EDT
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
