Software update failing for clients

Question

I have a Software Update server with unmanaged clients pointed to it. It's been running great for about 6 months, however recently client systems are having problems installing the 7.3.2 iTunes update. On the client side, Software Update will either crash or will fail with "A networking error has occurred: requested range not satisfiable (-1014)." Running "softwareupdate -i -a" returns "Package failed: requested range not satisfiable". So seemingly there's a problem with this particular update package on the server, but I'm not able to find this update in the /etc/swupd/com.apple.server.swupdate.plist.
Any recommendations on how to find and remove this update, then re-mirror it?
TIA,
chris
p.s. Also...any way to enable more extensive logging of clients using the SU server?

Answer 1

I had this exact same problem on several clients. In my case, for some reason the download -MUST- have been corrupted. Graphically, the softwareupdate service mentioned that iTunes was partially downloaded (3%)...
So I deleted the software update cache on one workstation
@ /var/root/Library/Caches/com.apple.SoftwareUpdate
At this path because I had ran the command, 'sudo softwareupdate -i -a'
and on a different workstation @
~/Library/Caches/com.apple.SoftwareUpdate
At this path because I had ran the graphical update utility, obviously without, 'sudo'
Either way, I deleted the cache, restarted the workstation, ran the softwareupdate check again and it installed iTunes without a problem. Give it a shot.
