Having the same exact experience on my 10.6.8 server. I also trashed the catalogs and had it do a complete re-download.

There is already another thread here about the current SUS issue. No real info other than "me too" and "Hmmm, Reposado is still working".

This is a wide spread problem.

Same issue here. For us its happening with anything released from 6/11 and on, so right on WWDC launch day. Same exact type of error in the logs (invalid request blah blah) Hmm is right. Did Apple change something that's causing our SUS's to break? Good grief...

Cool... Thanks everyone!

This discussion on the Apple boards seems to be pointing to a certificate issue.

Yep

Apple sus is very broken at the moment. It's a cert problem not matching the host name hosting the updates.

However reposado and the jamf NetBoot/sus both work fine. Yet another reason to drop Apples Sus and use a 3rd party one.

I'm seeing most of the updates that weren't downloading last week on our Apple SUS boxes, except for "Server Essentials". There are 5 of them listed, exactly the same size and version that still show up with exclamation marks next to their names. No big deal though, its not a show stopper. Fortunately the rest are now copied down, so looks like Apple resolved the issue for the most part.
