The above message says that the signature might be missing/invalid.
Debian uses a different file name for the signature file then ubuntu.

See the file list for comparison.
https://packages.ubuntu.com/focal/all/wireless-regdb/filelist
https://packages.debian.org/buster-backports/all/wireless-regdb/filelist

You can always download the latest wireless-regdb and replace the db +
signature files.
