Enabling back DSA keys
Starting with the 7.0 release of OpenSSH, support for ssh-dss keys has been disabled by default at runtime due to their inherit weakness.
If you have a legacy DSA key and you need to enable it temporarily, you can do by editing the file vendor/git-for-windows/etc/ssh/ssh_config
adding the following line
# Enables the DSA keys authentication.
PubkeyAcceptedKeyTypes=+ssh-dss
