I've been having a problem installing iTunes through the Apple Software Update cacheing server on OS X Server. it seems that when it tries to install it errors out saying the install is corrupt. what's the easiest way to clear our the update and have it re download?
You'll have to login to the server, or server app and delete the problematic update(s).
Remove software updates You can remove software updates from your Software Update server using the Server app. Select Updates In the Software Update pane. From the list of updates, select the update you want to remove. Click gear and choose Remove.
This should trigger the service to re-download the update again.
it's server.app's SU cache. I found some old instructions from AppleCare support, but they screwed up the config file. I tried following a workaround on your site, but it didn't work. I just found out how to uninstall and reinstall server.app, so I'm trying that now.
@chad.fox thank you for that! I tried it, and the newer versions of server.app are a little different, but it didn't work.
