For some reason, the JSS has started pointing machines to an incomplete URL for Apple updates. We use Apple's default, no SUS has been configured in the JSS but this is the log I get, both using policies or with the Remote app.
Setting Software Update Server to http://:/index.sucatalog for all accounts... Installing all available Software Updates... Result of Software Update: Error: Could not connect to the server. Software Update Tool Copyright 2002-2010 Apple
I've run the command
sudo jamf removeSWUSettingsjust in case but since manual update works, I doubt it has anything to do with the machine prefs.
I'm running out of ideas…
Thanks
