I am trying to upgrade an ASA-SSM-10 running version 5.1 software.
I have set up an FTP server using Serv-u and can connect to it successfully.
When I attempt to upgrade using the following command, I get the error below.
sensor(config)# upgrade ftp:[email protected]//IPS/IPS-K9-6.0-3-E1.pkg
The filename IPS-K9-6.0-3-E1.pkg is not a valid upgrade file type.
Continue with upgrade? : yes
Error: execUpgradeSoftware : Connect failed
I have tried 2 FTP servers and receive the same error I have tried 4 upgrade packages and receive the same error.
Does anyone have any advice on how to fix this issue.
