fatal: unable to access '<my_git>.git/': gnutls_handshake() failed: An unexpected TLS packet was received.
Might be issue with gnutls Package. we have to install a git Package with openssl instead of gnutls. Follow the below steps,
sudo apt-get install -y libcurl4-openssl-dev
sudo dpkg -i <git-openssl from release page>
