Manually downloaded the PRU since it has not been pulling them down. Put into a temporary directory on the Linux server (file is still zipped). At at command prompt (logged in as root), ran the command zman suei <temppath\directory\ -U=Administrator -P=<password>. System comes back
and tells me -System-update.invalidPermissions. This is the correct login
for the ZCC, used multiple times a day. Verified what was typed in, still
giving the error. Thought maybe it was just giving the error falsely, so logged into the ZCC and checked the system updates page- nothing there.

Any ideas on why it would say invalid permissions if the credentials are correct?
We only have the one account on the Zenworks server.
