Issue with cloning git repository

Question

I am trying to clone the git repository and i am getting error

Unable to negotiate with <server>: no matching key exchange method found.
Their offer: diffie-hellman-group1-sha1
fatal: Could not read from remote repository.

I edited ~/.ssh/config and added

Host somehost.example.org
KexAlgorithms +diffie-hellman-group1-sha1"

but still I am getting same error.

Other solution is to use the command ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 [email protected] -p 2222 but I am getting connection refused with port no 22 as well.

I am using windows machine.

Answer 1

touch ~/.ssh/config

attach my ssh config for people who come across the same issue

## use kex algorithm ##
Host 10.172.4.66
    KexAlgorithms diffie-hellman-group1-sha1

## Avoid Write failed : boken pipe issue ##
ServerAliveInterval 120
TCPKeepAlive no

use larger postBuffer if come accross another issue

fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

$ git config --global http.postBuffer 10000000000000000000000000000000

$ git clone ssh://xxx xx

Answer 2

Appending the file C:\Program Files\Git\etc\ssh\ssh_config with below content worked for me:

KexAlgorithms +diffie-hellman-group1-sha1,diffie-hellman-group14-sha1
