Phenomenon of the problem:

root@DESKTOP MINGW64 /f/git
$ git clone "ssh://abc@gerrit.abc.com:/test-repo"
Cloning into 'test-repo'...
Unable to negotiate with gerrit.abc.com port 12345: 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.

Cause of the problem: OpenSSH considers ssh-rsa encryption to be insecure and defaults to prohibiting ssh-rsa connection methods

Solution:

  • Modify C:\\Program Files\Git\etc\ssh\ssh_config

  • Add:

    Host *
    KexAlgorithms +diffie-hellman-group1-sha1
    HostkeyAlgorithms +ssh-dss,ssh-rsa
    PubkeyAcceptedKeyTypes +ssh-dss,ssh-rsa

Take effect after saving, can be cloned normally with git clone
