Hi,
We have 2120 appliance FTDs managed by FMC. FMC and FTDs have both version 7.0.1. We are planning to upgrade to 7.2.4. I have downloaded "Cisco_FTD_SSP_FP2K_Upgrade-7.2.4-165.sh.REL.tar" file. When i try to upload to the update file to FMC, it gives an error "Upload failed: Update is not a signed package.". I have rebooted FMC, it again gave the same error. I have tried to upload update package 7.2.5 and it still gave the same error. I have found the bug "CSCwd20551" and it says redownload the package. I have redownloaded the package but the result is the same, it gives the error "Upload failed: Update is not a signed package."
