I configured a machine with Ubuntu 20.04 and all worked fine.
Then I created an image with Clonezilla and restored it on an identical machine.
On the clone, the WiFi adapter is not available anymore:

I Google for error "-61" of iwlwifi but I found nothing useful.
Is there anything I have to do on a cloned machine to make the WiFi available?
