Symptom
The upgrade wizard shows that one of the devices needs the upgrade package.
This will be seen:
Devices > Device Management > select checkbox for the device(s) > for "Select Action" choose Upgrade Firepower Software
Conditions
Upgrade file is on the FTD, however FMC does not "see" the file as present.
Workaround
Restart sftunnel:
- ssh to the device
- go to "expert" mode:
expert
- elevate to root: sudo su
- enter password
- run the following as root:
pmtool restartbyid sftunnel
Further Problem Description
This instance of the problem was due to a time jump on the FTD. However, it is believed there are other ways in which this may be triggered.
