I am running Fedora Core 4 on an Intel Pentium IV system. I routinely run Yum Extendere to keep the system up to date, and it has been working well, without any problems.

However, today I tried to update, and now I'm having problems. First of all I'm get the following error:

Error in loading repository data

failure: repodata/repomd.xml in livna: [Errno 245] No more mirrors to try.

What known issues exist using the livan repository?
How important is the livna repository?
What does this repository provide for the distribution?
If this repository is significant, what should be done to fix it?

When I disable that repository, I can successfully obtain packages to update. One package available for update is dbus-qt. When I select the package for update, I get the following error:

Missing Dependency; dbug-qt = 0.33-3.1.fc4.kde is needed by package dbug-devel

Check ouput page for more info.

This is what the output page provides:
Setting up Update Process
['Missing Dependency: dbus-qt = 0.33-3.1.fc4.kde is needed by package dbus-devel']
Added 26 new packages, deleted 21 old in 6.13 seconds

What needs to be done to eliminate this dependency problem?

Livna is down. Add some mirrors like this
