Question

The following error appears when I try to clone git repository. I have the rsa public keys configured properly as well.

$ git clone https://github.com/blah/blah.git
Initialized empty Git repository in /home/arun/.git/
error: gnutls_handshake() failed: A TLS packet with unexpected length was
       received. while accessing https://github.com/blah/blah.git/info/refs

fatal: HTTP request failed

Answer 1

It could be used to a GnuTLs or pycurl bug

The following is the new method for pycurl_7.19.0-4ubuntu3:

sudo apt-get install build-essential fakeroot dpkg-dev
mkdir ~/python-pycurl-openssl
cd ~/python-pycurl-openssl
sudo apt-get source python-pycurl
sudo apt-get build-dep python-pycurl
sudo apt-get install libcurl4-openssl-dev
sudo dpkg-source -x pycurl_7.19.0-4ubuntu3.dsc
cd pycurl-7.19.0
# remove the HAVE_CURL_GNUTLS=1 in the following file
sudo vim debian/patches/10_setup.py.dpatch
# remove the HAVE_CURL_GNUTLS=1 in the following file
sudo vim setup.py
# replace all gnutls into openssl in the following file
sudo vim debian/control
sudo dpkg-buildpackage -rfakeroot -b
sudo dpkg -i ../python-pycurl_7.19.0-4ubuntu3_amd64.deb
