Unable to negotiate with xxx.xxx.xxx.xxx port 8080: no matching host key type found. Their offer: ssh-rsa
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

出现这个报错一般都是需要配置一下host和加密方式
具体配置如下：

Host xxxxxx
HostName xxxx
User  xxxx
Port xxx 
IdentityFile ~/.ssh/id_rsa   
HostKeyAlgorithms ssh-rsa
PubkeyAcceptedKeyTypes ssh-rsa

这个配置可以多个端口配置
也可以只配置 host *

MAC升级到 macOS Ventura后也会报这个错误
需要 touch一个config文件在~/.ssh目录下

cd ~/.ssh
touch config

然后进入目录，复制以下内容到文件中

最终试验可行

Host github.com
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/newed/id_ed25519

Host gitcode.net
  Port XXX
  AddKeysToAgent yes
  UseKeychain yes
  HostKeyAlgorithms ssh-rsa
  PubkeyAcceptedKeyTypes ssh-rsa
  IdentityFile ~/.ssh/id_rsa
