Unable to negotiate with XX.XXX.XX.XX: no matching host key type found. Their offer: ssh-dss
The recent openssh version deprecated DSA keys by default. You should suggest to your GIT provider to add some reasonable host key. Relying only on DSA is not a good idea.
As a workaround, you need to tell your ssh client that you want to accept DSA host keys, as described in the official documentation for legacy usage. You have few possibilities, but I recommend to add these lines into your ~/.ssh/config file:
Host your-remote-host
HostkeyAlgorithms +ssh-dss
Other possibility is to use environment variable GIT_SSH to specify these options:
GIT_SSH_COMMAND="ssh -oHostKeyAlgorithms=+ssh-dss" git clone ssh://user@host/path-to-repository标签：git,dss,问题,host,GIT,ssh,相关,your From： https://www.cnblogs.com/heysong/p/17294930.html
