Description

Hi,
gpg: keydb_get_keyblock failed: Invalid object
Is anyone got this issue?
Not just sign-only Curve448 subkey, gpg will fail after any subkey(RSA/ECC [S]/[E]/[A]/[C]) is created when a keypair is generated with Curve448.
gpg can not list new generating keys after this failure.

Details

Version: 2.3.2

Bug in creating such a blob is fixed in rG08a3a4db27dc: kbx: A 20 byte fingerprint is right filled in version 2 blob..

We need fix to specify version 5 key for ed448/cv448, for --edit-key/addkey.
