Description Michael Schwendt 2015-08-06 13:09:38 UTC 
dnf tells "Dependencies Resolved", but RPM's transaction check notices an undefined "%{epoch}" macro in a dependency. Yum is also affected.

For comparison:
bug 1251037 - Yum doesn't find undefined %epoch broken dep 


(!) 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.


# rpm -q dnf
dnf-1.0.2-3.fc22.noarch

# dnf install blktap-devel -y

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 16:47:42 UTC 
Followup to devel@ list. It's 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.
