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 C:\Users\MY_USERNAME\.ssh\config:
## 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.
