I am trying to upgrade the firmware on ASA's we have at multiple sites but for some reason copying over the firmware fails. We are currently running FP2140's in ASA mode and whenever I copy the files over from a windows machine, it fails. I am using scp to transfer the file over and the file begins to transfer. On the windows machine I see the progress of the transfer and on the ASA I see a temp file name of scp_1 which indicates the file is being transferred over. It takes 10 minutes or so for the transfer to say 100% on the windows box and then it fails with the error "Error: Signature not valid for file disk0:/cisco-asa-fp2k.9.18.4.22.spa. I was able to successfully transfer this image to our Nexus and even tried to scp it from the Nexus to the ASA but still no luck. Does anyone know how I can get this file up to the ASA so I can upgrade them?
