So, the same setup works for macOS El Capitan and the server supports:

nmap --script ssh2-enum-algos -sV -p 22 192.168.45.131      
Starting Nmap 7.95 ( https://nmap.org ) at 2024-05-24 09:46 EDT

I think I found what the issue is:

The problem
However, there is one case where this creates problems: Either the client itself or the server has a very old implementation of SSH that does not support rsa-sha2-256 or rsa-sha2-512 signatures, for example: OpenSSH <=7.2 which was released in 2016-02-29 ([release notes](https://www.openssh.com/txt/release-7.2?ref=ikarus.sg)).The problem

That being said both macOS Mavericks and Yosemite have ssh versions lower than 7.2.
https://ikarus.sg/rsa-is-not-dead/
Interrogating:

ssh -G [email protected] | grep pubkeyacceptedalgorithms
pubkeyacceptedalgorithms [email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],ssh-ed25519,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,[email protected],[email protected],rsa-sha2-512,rsa-sha2-256

one can see that ssh-rsa and ssh-dss are missing.

So I have added to my config file:

Host *
  PubkeyAcceptedAlgorithms +ssh-rsa,ssh-dss
  HostKeyAlgorithms +ssh-rsa,ssh-dss

ssh -G [email protected] | grep pubkeyacceptedalgorithms
pubkeyacceptedalgorithms [email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],[email protected],ssh-ed25519,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,[email protected],[email protected],rsa-sha2-512,rsa-sha2-256,ssh-rsa,ssh-dss

And -var 'temporary_key_pair_type=rsa' -var 'temporary_key_pair_bits=1024'
But I still get

I have also tried to upgrade the openssh inside the server, but could not get rid of this error.

I wonder if it is possible directly to add variable to golang?

-var 'sshConfig.Config.KEXAlgos = append(sshConfig.Config.KEXAlgos, "diffie-hellman-group-exchange-sha256")'

We're using the Go library directly for performing SSH-related operations, so I'm not sure there's a lot that OpenSSH supports that we do too.
Honestly though you're not the first one noticing that our SSH code is a bit rigid, we should spend time on that front to see what we can do to make it more robust.
Can't promise when that will happen, but we'll try to schedule some work on this ASAP.

Hey @startergo,

No progress yet, it's in my backlog but I haven't had time to look at it yet, still cannot promise when that'll happen unfortunately, sorry about that :/
