For over a month, a broken "blktap" package had been in Rawhide without
being discovered by the broken deps report. Meanwhile, a fixed blktap
package has been released into Rawhide, but the broken deps report likely
still suffers from the problem as described below.
What creates the Rawhide broken deps report nowadays?
Is it able to discover undefined %{epoch} values in dependencies?
{{{
> Broken deps for x86_64
Surprisingly, the report is incomplete and doesn't find some unresolvable
dependencies. DNF doesn't either.
An undefined %{epoch} in a dependency is not found. This has been reported
to blktap: https://bugzilla.redhat.com/1248912
Note how DNF tells "Dependencies resolved", but later fails during the
transaction check. How could it resolve the unexpanded "%{epoch}" earlier?
$ rpm -qpR blktap-devel-3.0.0-3.fc23.git0.9.2.x86_64.rpm |grep ep
blktap(x86-64) = %{epoch}:3.0.0-3.fc23.git0.9.2
$ dnf install blktap-devel

Running transaction check
Error: transaction check vs depsolve:
blktap(x86-64) = %{epoch}:3.0.0-3.fc23.git0.9.2 is needed by blktap-
devel-3.0.0-3.fc23.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.
