Apple recently released a 10.7.5 Supplemental Update to fix a few issues with the original 10.7.5 full update. This update is available via Apple's own Software Update Server and via a manual download.
I am running an internal Software Update Server in Mac OS X 10.7.5 with Server.app 1.4.3 and this has been successfully downloading and distributing updates from Apple including the original 10.7.5 update. However currently the 10.7.5 Supplemental Update is stuck showing an ! (exclamation mark) in Server Admin - Software Update Server, and the copy now button does nothing.
Note: my SUS is set to download all new updates automatically but not to enable them.
I have tried stopping and starting SUS but that made no difference either. Has anyone else been able to get their SUS to download this update?
I found the following error in the Software Update Service Log
Oct 8 14:16:46 lon01-macmgmt-01.local swupd_syncd <Warning>: ignored invalid download request for product 041-7698, current state = PleaseMirror
The package 041-7698 corresponds to the update I am referring to.
I'm having this problem too. But it appears that all Lion updates are having this issue.
Snow leopard, etc seem to be downloading and pushing fine, but any Lion updates I can't copy down and they all have the "!" beside them.
My log reports almost the exact same message as yours.
The server is updating itself not a problem as well.
