When I tried to update the Images in Cisco’s VIRL User Workspace Management, all the images would fail. I would get what you see below: I first tried IOSvL2 and then ASAv. They both gave me the same results. This command fixed the issue. You have to jump on the CentOS CLI and run it. sudo salt-call saltutil.sync_all After running that command, all the images installed with no issues.
