You don't have a signing key.  Ther primary key has been taken offline
('#') and can thus not be used for signing.

The subkey is not capable of signing (by usage flags and algorithm).

Did you had another signing subkey and that one expired?
Add

  --list-options show-unusable-subkeys

to the listing command to check.
