[aboe76]

fedora 22 will use dnf by default and won't be shipping yum:

so far testing 2015.5.0 with fedora 22 is ok, package installation works because
server edition has still a /usr/bin/yum which redirects to /usr/bin/dnf

yum
Yum command has been deprecated, redirecting to '/usr/bin/dnf '.
See 'man dnf' and 'man yum2dnf' for more information.
To transfer transaction metadata from yum to DNF, run:
'dnf install python-dnf-plugins-extras-migrate && dnf-2 migrate'

see also the release notes:

DNF (Dandified YUM) replaced YUM (Yellowdog Updater, Modified). DNF and Hawkey are the package managers in Fedora 22. DNF working style is very much similar to YUM but re-engineered to get optimal performance. Server and cloud users can continue to work with yum but with the message that “YUM is Deprecated and DNF is the latest Package Manager”.

haven't tried the fedora 22 workstation or cloud version to verify this.

another source is man yum2dnf:

I can confirm Fedora 22 Workstation have problem with pkg module:

I created PR #26572 to start this issue, #23553, and fix #26340 .

Thanks go to terminalmage for writing the helper function, and iggy for giving ideas.

Do we need another issue to remove the package dependency on yum/yum-utils?

[terminalmage]

Salt supports dnf starting with version 2015.8.0. In the develop branch, reliance on yum-utils has been removed, so this is not going to be an issue moving forward.

As for the 2015.5 release cycle, since we have packages in the Fedora 23 repos (Fedora 22 will display a warning but still does work if the yum command is run) I will need to backport the dnf support from 2015.8 into the 2015.5 branch and use the repoquery plugin for dnf, thus allowing future 2015.5 and 2015.8 releases for Fedora to use dnf-plugins-core instead of yum-utils.

[terminalmage]

DNF support has been backported to the 2015.5 branch in #30484. This did not make it in time for 2015.5.9 to be released, but when I build the 2015.5.9 RPMs for Fedora I will patch the source to include the new code from that pull request.

[terminalmage]

#30484 was merged and Fedora RPMs have been built and submitted to testing. They should make their way into the stable repos in the next 8-10 days.

Within the next 2 days or so, Fedora 22, 23, and Rawhide users will be able to upgrade using dnf --enablerepo=updates-testing install salt-minion

Marking this as closed.
