Hello, I use to update every days with Fedora yum from the beginning of the world, I installed F22 on 26 of may, everything was perfect. Since 07 of June 2015 update fails regularly with Yumex F22 with the message (translate from French => " Error in dependencies search"...). I discover some misfits, but maybe some misinterpretation on my side :

I tried :

sudo dnf clean metadata
sudo dnf update

But no progress It fails always When I read journalctl Insert not installed package in list-update Examples => From journalctl last lines :

Package git-core not installed, cannot update it.
Package python-osbs not installed, cannot update it.
Package python-networkx-core not installed, cannot update it.
python-ipaddress not installed, cannot update it.
python-idna not installed, cannot update it.
Package plasma-desktop-doc not installed, cannot update it.
perl-open not installed, cannot update it.
Package perl-encoding not installed, cannot update it.
Package kf5-modemmanager-qt not installed, cannot update it.

I deselect these packages before running UPDATE with Yumex Now the search for dependencies is correct, but In the list provided after dependencies resolution, I have in the "To install category" the packages I previously deselected => Is that a bug ?

Nevertheless I start the update process, it begins correctly ... after a while .... a screen splash with a download error message and the list of the done downloaded packages and the process stops. On jourrnalctl no message about failure.. Something goes wrong, maybe Yumex

Some hints will be a great help. Thanks

I'm not sure I understand this clearly. You're using DNF - but DNF is a command line client - you don't get splash messages. Can you confirm what you're using please?

Also, is this a fresh install or a system that was upgraded from F21 or a previous Fedora version?

Yes I use DNF with its GUI improperly named Yum extender on F22. I Fedup from F21 to F22. This install is working since the 26 of May. In fact the splash is not a problem. The problem starts IMHO with the presence or Update packages for not installed packages in the update list provided by the YUM/DNF Extender after launching. Thanks for yout follow up!

YUM extender is a front-end, it isn't the same thing as DNF. Since you used fedup, did you run a distro-sync to clean up older packages from your system? I recommend:

sudo dnf clean all; sudo dnf distro-sync

see if that helps.

That Yumex is now the front-end of dnf on F22 instead of yum previously I understand that perfectly. I run

sudo dnf clean all; sudo dnf distro-sync

Then with Yumex-dnf I've the same result as indicated in my first post with proposal for update of not installed Packages with conflict about dependencies.

With the dnf command line => dnf check-update provides the same list, with releases for not installed packagres and

dnf upgrade --best

fails with dependencies error

Hello, About the the title, of this thread, which has been changed, IMHO it is not a YUMEX issue but a DNF issue [ Presence in the update list of not installed packages for upgrade], this issue is visible with the DNF command line and through the YUMEX GUI which is the front-end of DNF. If not right, let me know please Thanks for your follow up

This post is a wiki. Anyone with karma >750 is welcome to improve it.

I went through an erratic process to fix that :

  1. First I installed the missing packages for which updating was proposed, with the dnf cli,
  2. I unchecked plasma-desktop-doc for update from dnf-yumex
  3. I updated all the packages list from dnf-yumex
  4. I uninstalled plasma-desktop-doc (impossible to update) from dnf-yumex
  5. I left dnf-yumex, and from the dnf cli I install the last release of plasma-desktop-doc
  6. I restart dnf-yumex, no proposed update, everything ok ! I left dnf-yumex
  7. last caution, from cli dnf => sudo dnf clean all; sudo dnf distro-sync It's OK but I have not a great mastering of dnf -yumex. Maybe these different steps could help others. This thread can be closed. Thanks to Francisco and David for their interest.

Remember Yumex uses 'yum'; exist a next Generation of yumex, using dnf as backend. Why no try yumex-dnf

dnf copr enable timlau/yumex-dnf
dnf -y install yumex-dnf

Thanks, you are correct I used of course yumex-dnf. It was setup during the Fedup F21=>F22. Not sure but I presume, Francisco has changed the title of this thread IMHO it is a DNF issue or maybe my previous local repository was corrupted. But I fixed the problem according to the answer..

Thanks for your help
