Using “KexAlgorithms diffie-hellman-group1-sha1” did not resolve “no matching key exchange method found” error
There’s a lot of questions about the following error, but they all have same solution which did not have any effect:
$ git push Unable to negotiate with 192.168.XXX.XXX: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1 fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
There is an article on openssh.com that didn’t help. Particularly this was suggested:
… in the ~/.ssh/config file:
Host somehost.example.org KexAlgorithms +diffie-hellman-group1-sha1
I did exactly that. I assume that
~ resolves to
%userprofile% on windows. My file is in
## use kex algorithm ## Host 192.168.XXX.XXX KexAlgorithms diffie-hellman-group1-sha1
The result is that nothing changed. There is also suggestion to use
ssh -o but I’m yet to find an answer that bothers to describe how exactly yo do that. I tried this:
$ ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 usage: ssh [-1246AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]
I need to connect to that GIT repository. I am on windows. The repository uses Gerrit. I also use SourceTree and it has no problems pushing into the repository. So the repository works, but git or openSSH in my bash is broken.
What did I do wrong that this solution didn’t work for me?

Resolved by using this command I randomly found in some comment thread:
export GIT_SSH_COMMAND='ssh -o KexAlgorithms=+diffie-hellman-group1-sha1'
Must be called every time you open the Git Bash. Yeah, git is hell.
I resolved a similar problem on Windows 10 by updating my version of Open SSH to the latest (7.5p1-1) and then making sure that C:Program Files\OpenSSH\bin was the first entry in the system path so it used that ssh.exe and not any others.
