ledger-agent does not work with ED25519 #26

It looks like ledger-agent on Mac is having some issues with ED25519. Upon generating the keys and trying to connect I am getting following warning and authorization ends.

2020-05-05 19:24:33,776 WARNING Unsupported command: SSH2_AGENTC_ADD_IDENTITY (17) [protocol.py:98]

When I switch to ECDSA, all is working just fine

I don't think Ledger supports EdDSA (Curve25519), only ECDSA.

Correct me if I'm wrong, but I think it's a firmware limitation.

dylangerdaly commented 4 years ago

Ignore the above, the ledger totally supports Ed22519/EdDSA.

Looks like it takes forever to fix issues

I wonder if this could not be a server setting issue? I also got that message...
