firepower1120 upgrade fail

[shiran.wang]

Cisco 1120 HA pair management be FMC 1600, FMC version is 7.0.1 with hotfix 7.0.1.10, FTD 1200 is new installed device the version is 6.4.1, why try upgrade to 7.0.1 there is a wrong message "Failure, Signature verification failed"

upgrade to 6.6.4 have same error message.

MD5 check it correct, and 1120 VDB version same as FMC, 

may I know what's wrong with "Failure, Signature verification failed"

Hello,

hard to say what is going on. Since you are doing the upgrade on an HA, did you pause synchronization ?

thanks for your reply,

  the issue fixed, it caused by register pending, maybe it write wrong FMC's IP address when first time register,

"show managers" there is a "pending" and another is normal registered

> show managers
Type : Manager
Host : 192.168.2.10

Registration : Completed

Type : Manager
Host : 172.16.2.10

Registration : pending

> configure manager delete (it work after do this command)
