We have got two ASA 5525-x with sfr modules. They lived a couple off years without functioning on version 5.4.0. Now for test whe want to upgrade them with new software. One was easy.. without any error. But the second (did exactly the same) gives an error after he tries to extract the .pkg.
asasfr-boot>system install noconfirm http://xx.xx.xx.xx/asasfr-sys-6.2.3-83.pkg
Unknown error occured
The logfiles gives nothing..
What can it be? Whe suspect the ssd.. but can't check it..
the reason for this is because of the link between the sfr and the http where the file is.
try to do ftp instead of http. or make sure the connection is a good link no ping loss etc.
