We have found some bugs in PackageKit and related components which require an update to fix. Unfortunately, the bugs can prevent Fedora Workstation’s default update mechanism – the ‘offline update’ system, where a notification of new updates appears, and you reboot to install them – from working correctly. The bugs can also cause problems with software installation and/or removal when using GNOME Software or Apper (the KDE software manager).
If you have tried to do an offline update recently, you may have seen a notification that it failed.
If you usually apply system updates using the ‘offline update’ mechanism or another PackageKit-based application, then to resolve this problem, we recommend that you run the following
command with root privileges:
yum update --advisory=FEDORA-2015-0921
To do this, for instance, if you are an admin user, you can run:
sudo yum update --advisory=FEDORA-2015-0921
Or if you have the root password, you can run:
su -c 'yum update --advisory=FEDORA-2015-0921'
either way, a few packages including PackageKit and libhif should be updated. You may then wish to reboot the system (though in most cases it should not be necessary).
Usually, this should be sufficient to resolve the bugs in question, and you can then do future system updates using the ‘offline update’ system. If you continue to have problems, you should run this command:
and then reboot the system. If you still have problems after this, please file a bug report.
We do sincerely apologize for any inconvenience caused by these bugs.
