Karl tries to switch between several disabled and still partially
incompatible repos and fails. For example, as soon as the older x264
package from freshrpms upgrades the newer x264 package from livna due
to how RPM version comparison works, that is a problem which Karl is
not capable enough to solve himself. That's why he blames the
repositories or Fedora instead of himself. Some package contents are
fully incompatible, unfortunately. They disturb yum updates and also
attempts at installing new software that requires them. It's a dead
end for the majority of Fedora users. Recovery is needed, and as has
been shown, "yum remove..." is not ready yet for the masses.

The lame problems in these two recent threads is unrelated. They are a
clear sign of inability to communicate via a mailing-list. And they
show that Karl is not really interested in solving the problem.
Instead of concentrating on analysing the problem together with the
assistance of list subscribers, the threads are turnt into an
irrelevant chat-like conversation. The details get buried. Every 50
messages it is repeated that after modifying some files and running an
unknown number of commands the problem still occurs. Instead, it would
be important to collect new data, post the complete session history
(every "yum clean...", every "rm -rf ...", the latest "df" output),
repost the full output of the last "yum install ..." installation
attempt, too, and to do the same for every suggested command.
Half-hearted trouble-shooting won't be successful. It's not that it's
a hard problem, the person who has the problem is just not motivated.

It's been several years since the first general Fedora users have run
into issues when trying to mix packages from repositories with
overlapping contents. Apt-pinning, Yum-priorities and SmartPM's
downgrade strategies are attempts at working around such problems.
Sure, you can be successful when cherry-picking single packages. Small
ones, or built against Fedora base packages only. But if they pull in
lots of requirements from the external repository, your dependency on
that repository increases, and it becomes more likely that another
repository causes conflicts of some sort. And normal yum updates might
become a burden, since it has been encountered before that packages
from different repos upgrade eachother.
