I'm sorry, but this does not solve my problem: Downloading all needed dbus-1.8.12-3* packages from KOJI to some local dir:

Error Summary
-------------

You should not be able to install the dbus package for two architectures simultaneously, as /etc/dbus-1/system.conf conflicts, so the error reported by yum is correct, and also in the case of -1 release of the packages. The standard behaviour of "yum update" is to update (and install) every package given, including the ones which are not currently installed. Remove the i686 dbus and dbus-x11 .rpm files and try again.

Hi David,

Both on my F20 and my F21 box, the x86_64 and the i686 variant of dbus packages are installed, und I'm sure I did not explicetly install both arch's.

So how to resolve this conflict? trying to remove the dbus* i686 pkgs will remove a (huge) lot of other i686 pkgs depending on the i686 variant of dbus on my box :-(

Regards

Joachim Backes

With the -3 update, the dependencies of the subpackages on the dbus package are the same as those in the -1 package, so this conflict is not caused by the update.

The problem is that you are telling rpm (or yum, dnf and so on) explicitly to install conflicting packages, as you have downloaded the rpm files from Koji directly (which roughly corresponds to the latest repositories described at https://fedoraproject.org/wiki/Repositories#The_latest_repositories). When you say that you have both the i686 and x86_64 versions of dbus installed, the files in the filesystem are only provided by the x86_64 package. Multilib support in the package manager means that both i686 and x86_64 packages can be installed simultaneously, with the files from the preferred architecture being the ones that end up in the filesystem.

If you want to test the update, you should wait until it enters updates-testing, and install it from there (after mash has been run to handle multilib issues such as this).

Even without downloading some rpm, I always get the error message


Error: Transaction check error:
  file /etc/dbus-1/system.conf conflicts between attempted installs of dbus-1:1.8.12-2.fc21.i686 and dbus-1:1.8.12-2.fc21.x86_64


if running a pure "yum update" or "dnf update" without parameters.

The -3 update has not yet entered updates-testing (or rather, today's sync to mirrors has not yet occurred), so please wait until then and test again.

The i686 version of the dbus package (dbus-1:1.8.12-1.fc21.i686) is not in the updates repository (you can check at http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/fedora/linux/updates/21/x86_64/d/ or another mirror), so if you have that package installed, then it probably did not go through the mash process, and you should uninstall it, or wait until the -3 update is in updates-testing.

Package dbus-1.8.12-3.fc21:
* should fix your issue,
* was pushed to the Fedora 21 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing dbus-1.8.12-3.fc21'
as soon as you are able to, then reboot.
Please go to the following url:

then log in and leave karma (feedback).

dbus-1.6.28-3.fc20 has been pushed to the Fedora 20 stable repository.  If problems still persist, please make note of it in this bug report.
