README.md

I wasn't able to git fetch from Azure DevOps repos after upgrading openssh on my computer.

ssh -V
  OpenSSH_8.8p1, OpenSSL 1.1.1l  24 Aug 2021

Turns out that OpenSSL has now turned off ssh-rsa by default:

This release disables RSA signatures using the SHA-1 hash algorithm by default.

But Azure DevOps doesn't support anything else... Add the following to your config file to re-enable ssh-rsa for Azure DevOps:

cat  ~/.ssh/config
  Host ssh.dev.azure.com
      IdentityFile ~/.ssh/azuredevops_rsa
      HostKeyAlgorithms +ssh-rsa
      PubkeyAcceptedKeyTypes +ssh-rsa
