Even though we’re using a HTTP/S distribution point, that should allow for resumable downloads we sometimes see the above error.

Below are some more details around this, and a break-fix.

The error

An error occurred executing the policy “Install 010 dockutil 1.1.4″ on the computer “xxx”.
 
Event log from the policy:

The fix

We do that running the below via ARD or by SSHing into the Mac having the issue.  You could turn it into a script & run it from Casper over AFP/SMB too.

For whatever reason, the resumable download doesn’t complete.. requiring the /Library/Application\ Support/JAMF/Downloads/ folder to be emptied.

sudo rm -rf /Library/Application\ Support/JAMF/Downloads/*

Once run, retry the policies that had previously errored.
