Thanks for the report. This command works: `dnf install qt-devel-1:4.8.6-18.fc21.x86_64`. The problem is in hawkey.Selector where we expect that epoch is 0. Michael, take a look, please. We should support arguments `epoch` and `release` in hawkey.Selector constructor if possible.
*** Bug 1235453 has been marked as a duplicate of this bug. ***
This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 21 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.
More information and reason for this action is here:
FTR this can be done through query and using new support of Selector.set(pkg=...).
The problem is solved by PR: https://github.com/rpm-software-management/dnf/pull/647.
It simply use query and selector pkg flag to prevent a problems with epoch and selectors.
