I am trying to update our zcm 10.3.3 agent with 4 updates and when I run the zman sui command from the server, it completes successfully and you can start to see the update download into ZCM, but it gets to about 40% and then gets an error. The error states: The downloaded system update files appear to be corrupted. Try to re-download the update again. I did a md5sum on the zipped packages when I downloaded them and they all checked out. The 4 updates I am doing are the following: ZCM 10.3.3 patch for 'Cosmetic' error message when deploying bundles after 10.3.3 updated - See TID 7008298, ZCM 10.3.3 Bundle.RunOnceWarning patch - see TID 7007319, ZCM 10.3.3 iPrint on Windows 7 fix - see TID 7008738, and ZCM 10.3.3 Allow 'workstation only' login on Windows 7 - see TID 7007888. I replace all of the necessary files in the zcm 10.3.3 update and change the necessary checksum values in the update.xml file. I am confused as to why this continues to error out.
