Cannot Update without Private Key

Unfortunately I cannot add my public key through terminal. Chris suggested me to use keybase pgp update but it does not work.

Is there any way to add only public key (without private ones)

Start by reproducing the reported failure with the `keybase pgp update` command in a terminal and determine how public and private keys are currently handled. Review the relevant Keybase client entry point and documentation; done means establishing whether a public key can be added without private key material and documenting or implementing the supported behavior.
