On ZCM 10.2, under System Updates, we told it to download the 10.2.2 update. Unfortunately, we did not realize that the disk space was too low so the download failed with a Status of "Error". So far, doing what it should. Clicking the "Error" status in the Available System Updates list shows "Cannot download update due to insufficient storage space on download server". Yep - that was true.

Now - we have fixed the disk space problem but can't seem to coax it to try the download again. If we try it, we simply get a "Error: There was a problem initiating the download" error message at the top of the page. So then we try to delete the failed update and get the message "Error: Failed to delete update".

Any ideas on how to clear the error so that it will attempt the download again? I have not found anything obvious.
