ssh [email protected]
結果:
Unable to negotiate with xxx.xxx.xxx.xxx port 22: no matching host key type found. Their offer: ssh-dss

私の公開鍵をサーバー上のファイル~/.ssh/id_rsa.pubに追加しました。~/.ssh/authorized_keysssh-rsa
私はUbuntuで使用していますOpenSSH_7.2p2 Ubuntu-4ubuntu1, OpenSSL 1.0.2g-fips 1 Mar 2016（MintシステムのSSHバージョンがわかりません。サーバーがCentOSを実行しているようです）。
私は何が間違っていましたか？
ただ楽しさで以下を追加しました。
# http://www.openssh.com/legacy.html
Host xxxxxxx.xxx
HostkeyAlgorithms +ssh-dss
到着する.ssh/config。
~/.ssh/authorized_keys接続は成功しましたが、公開DSAキーがないため、パスワードを入力し続ける必要があります。
16.04 LTSそれでは、RSAを使用するSSHが私のUbuntuシステムで機能しないのはなぜですか？
