The offered update is the one from which I downgraded, i.e. the one that fails to load.

Apologies if I have not provided sufficient or the right information - this is the first Fedora bug I've raised before.

Confirmed with:
powerdevil-5.4.3-1.fc22.x86_64
kf5-kded-5.15.0-1.fc22.x86_64

As noted in the duplicate Bug 1282594, renaming/removing the file /usr/share/kservices5/kded/powerdevil.desktop makes KDE usable again.

Bug 1282324 is another dup.

Regenerating powerdevil RPM fixed the issue for me. Tried with two users: mine and a test one created fresh that I used to reproduce the issue.

Login is slow (but this is another bug) but it works. To recompile the RPM I used:

mock --arch=x86_64 --root=fedora-22-x86_64 powerdevil-5.4.3-1.fc22.src.rpm

mock config files are the default, I never changed them

I can confirm that downgrading to 5.3.0 also solves the problem.

The problem is that powerdevil-5.4.3-1 was built against qt5-qtbase-5.5.1-4 but F22 repos only contain qt5-qbase-5.5.0-18

https://kojipkgs.fedoraproject.org//packages/powerdevil/5.4.3/1.fc22/data/logs/x86_64/root.log shows:

DEBUG util.py:393:   --> qt5-qtbase-devel-5.5.1-4.fc22.x86_64

$ rpm -q qt5-qtbase
qt5-qtbase-5.5.0-18.fc22.x86_64


qt5-qtbase is still in updates-testing, but packages the depend on it have already been pushed to stable

https://bodhi.fedoraproject.org/updates/FEDORA-2015-3c671e20a3 contains the required update

I can confirm that powerdevil-5.4.3-1 works OK after installing qt-qtbase-5.5.1-8.fc22 using:

Also works for me with testing version of qt5

Thanks to all for a very speedy resolution!

On a second independent system, again Fedora 22 KDE spin based, I tried the updated qt5 5.5.1 packages from updates-testing and they indeed worked like a charm.

However I noticed I had to use the following command to update all packages and not just some of them (note I use fish as a shell, you have to change it for use in bash):

dnf update --enablerepo=updates-testing (rpm -qa | grep '^qt5.*-5\.5\.0.*')

With this the following 4 packages were updated as well

Transaction performed with:
    Installed     dnf-1.1.3-1.fc22.noarch     @updates
    Installed     rpm-4.12.0.1-13.fc22.x86_64 @updates

    Upgrade                            5.5.1-2.fc22.x86_64 @updates-testing

Since, as far as I know, it is quite critical to keep all qt packages at the same version I thought it was worth sharing.

I think this is not a resolution.
Instead I think that there are a lot of bugs on the stable repos.

I had a similar problem with wine, that after dnf update didn't work.
After an intensive search on solving the problem, I updated from testing and magically it starts working again.
I think we need more stable and reliable distros.

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

FWIW I think this was fixed, rather than just EOLd.
