Using RemoteUpdateManager on Mac labs is returning exit code 0 right away, howeve the product is still on version 2015.1 instead of 2015.5

I have never had this problem before updating my Adobe CC produts for the Mac Labs at the school I work at. Normally I just shoot out the terminal command

usr/local/bin/remoteupdatemanager

and the products begin updating themselves. For some reason in this case, they are returning exit code 0, but when I check the products they are still stuck on 2015.1

Any advice is appreciated!
