I've got a pair of FPR-1150 firewalls running ASA software 9.16(2)14. I'm trying to upgrade to 9.20(3)13. I've downloaded the SPA file and verified the md5. When I issue the "boot system disk0:/cisco-asa-fp1k.9.20.3.13.SPA" command, it goes through the steps that I would expect, successfully unpacks the image, displays "Install_status: ready", then "Install_status: validating-images", then gives the error:
ERROR: Unable to set this url
and drops me back to the config-mode prompt. When I "show running-config", there is no "boot system" command present. Just to be sure it wasn't doing something unexpected, I did a "write mem" and system reload, and it reloaded to the same version it had been running.
