I have a web application mounted on an old server with Ubuntu 10.04.4 LTS and for a short time I have not been able to deploy it due to a problem that occurs with the connection to github to download the code:
no matching mac found: client
hmac-md5,hmac-sha1,umac-64@openssh.com,hmac-ripemd160,hmac-ripemd160@openssh.com,hmac-sha1-96,hmac-md5-96
server
hmac-sha2-512-etm@openssh.com,hmac-sha2-256-etm@openssh.com,hmac-sha2-512,hmac-sha2-256
fatal: The remote end hung up unexpectedly
The problem seems to be caused by a recent change in github that does not accept connections with old protocols, here they explain it: https://github.blog/2021-09-01-improving-git-protocol-security-github/
This is the ssh version of my Ubuntu server:
ssh -V
OpenSSH_5.3p1 Debian-3ubuntu7.1, OpenSSL 0.9.8k 25 Mar 2009
Which by the way does not support the -Q option that is proposed in some responses to similar questions that have not helped me to solve the problem.
ssh: illegal option -- Q

The ssh_config file for my server is this:
# $OpenBSD: ssh_config,v 1.34 2019/02/04 02:39:42 dtucker Exp $
# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

Could someone help me to fix this issue considering I am tied to that server running Ubuntu 10.04.4 LTS? Thank you very much.
