no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group14-sha1

I have created a git repo which uses ssh to connect.

got the error "no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group14-sha1".

try to attach to the docker, log in as user root.

created a confi file under root/.ssh. has content

KexAlgorithms +diffie-hellman-group1-sha1

I can use the same command in the shell

git ls-remote MYREPO refs/heads/master

I don't get any error.

however, still get the error in git-repo of fleet.

I guess the config file doesn't work in this case. however, what is the correct to way to make it work?

Found the solution.

but still wonder if I can config this in client side gitrepo?
