For something like a week or two yum autoupdate on my system has been
failing with the message

    Failed to check for updates with the following error message:
    Failed to build transaction: libgpod-0.8.3-14.el7.x86_64 requires
    libplist.so.1()(64bit)
    libgpod-0.8.3-14.el7.x86_64 requires libimobiledevice.so.4()(64bit)
    libgpod-0.8.3-14.el7.x86_64 requires libusbmuxd.so.2()(64bit)

Each of the required files is currently installed on my system.  If,
which is doubtful, I understand the error output from Yum Extender
(shown below), the problem somehow arises from the fact that "yum update"
is trying to replace those required files with later versions.  I can
find no information about how to resolve the situation. "Yum clean"
hasn’t helped.

There are something like 270 packages currently requiring updating on my
system, but the errors appear to be (for me) showstoppers.  --skip-broken
now skips all of them, since I ran it earlier to install whatever packages
I could.  If there are any obvious routes of attack on the problem, I
would appreciate hearing about them.  But I am not an admin type, so if
the problem is complex, I would also be interested in knowing whether
there is a resource somewhere where one can find (qualified!) admins who
are in the market for occasional, long-distance, paid consultation.  I
could use such a connection in any case as an alternative to bothering
this list — in which, I am afraid, I really don’t belong (although I do
receive useful information from *reading* it).

Many thanks.
