Sigchain specified that KID XXX is a PGP key with hash YYY but no version of the key with that hash was found (error 901)

Hey All,

I am trying to login to keybase on the Linux command line:

```
> keybase login
How would you like to sign this install of Keybase?

(1) Use an existing device
(2) Use a paper key
(3) Use my Keybase passphrase
(4) Use GPG
Choose a signing option: 4
In order to authorize this installation, keybase needs to sign this installation
with your GPG secret key.

You have two options.

(1) Keybase can use GPG commands to sign the installation.

(2) Keybase can export your secret key from GPG and save it to keybase's local encrypted
keyring. This way, it can be used in 'keybase pgp sign' and 'keybase pgp decrypt'
going forward.
Which do you prefer?: 1
# Algo Key Id Created UserId
= ==== ====== ======= ======

Choose a key: 3
```

but I get an error...

```
▶ ERROR Sigchain specified that KID XXX is a PGP key with hash YYY but no version of the key with that hash was found (error 901)
```

I have tried this on a couple of machines and I can't seem to get it working. The public key I used is listed in the "Which do you prefer" list and I select the public key I loaded up on Keybase.

It is likely something silly I am not understanding.

Riproduci il flusso di `keybase login` utilizzando l’opzione GPG e la chiave selezionata, quindi traccia la gestione dell’errore 901 e dell’hash della chiave segnalato. La descrizione non indica file sorgente né test; il lavoro sarà considerato completato quando sarà stato identificato il motivo per cui la chiave selezionata non viene trovata tramite il suo hash registrato e tale problema sarà stato documentato o corretto.

Scritto dal modello di indicizzazione a partire dal testo della issue.
