我最近更新了Ubuntu系统，然后发现更新版本不再支持我正在使用的SSH功能。
如何将 sshd.service 恢复到以前的版本？
（是的，我确实知道旧的寿司需要更新，这也会发生）
我尝试在/etc/ssh/ssh_config客户端上添加以下内容来解决此问题：
HostKeyAlgorithms +ssh-rsa
PubkeyAcceptedKeyTypes +ssh-rsa
但我仍然看到：
debug2: service_accept: ssh-userauth
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug1: Authentications that can continue: publickey,password,keyboard-interactive
debug1: Next authentication method: publickey
debug1: Offering public key: /home/its_demo2/.ssh/id_rsa.pub RSA SHA256:Ml5N2i3iOCN04zqjnpT1y7dQvKOQZT9zsOT5GPE5KFk explicit
debug1: send_pubkey_test: no mutual signature algorithm
debug2: we did not send a packet, disable method
