I tried to implement fetch and this exception was raised:
Rugged::NetworkError: This transport isn\'t implemented. Sorry

libgit2 uses openssl for HTTPS and libssh2 for ssh. You need the development packages for them in order for the embedded libgit2 to build with support for those transports.
Just to follow up on this, you need to install these:
openssl libssh2 libssl-dev pkg-config
Then you need to reinstall libgit2(rebuild), because the original shared libraries do not know that you've installed the new packages. See http://www.pygit2.org/install.html for installing.
