"skipped: Unusable public key"

[Philihp Busby]

It appears that 3C5B212A55B966881E2D2718A45398B520BEE91E does not have the [E] usage for encryption, nor does it have any subkeys with that usage. This subkey would have been created by default when the master key was created. See if you can recover it?
