--- Comment #42 from Lukáš Turek <8...@8an.cz> --- Unfortunately you're right, it didn't help, it really seems the RFC8308 extension is needed, which requires MINA SSHD version 2.3.0 or later. Do we really need to use RSA for client authentication? Or could the KDE Connect client (Linux app) also switch to an ECDSA key? The error "no mutual signature algorithm" does not appear when I try to send my ECDSA public key: debug1: Next authentication method: publickey debug1: Offering public key: id_rsa RSA SHA256:En18wk81oylB2/tXALRVR665pvuP3XHZOVUdTWnZ06w agent debug1: send_pubkey_test: no mutual signature algorithm debug1: Offering public key: id_ecdsa ECDSA SHA256:JL1U9qfHt51GmmiT41JB9WDRDP4cWWA8H/boCR08qCU explicit debug2: we sent a publickey packet, wait for reply -- You are receiving this mail because: You are watching all bug changes.
