sudo apt-get install libneon27
cd /usr/lib
sudo rm libneon-gnutls.so.27
sudo ln -s /usr/lib/libneon.so.27 libneon-gnutls.so.27 (double check that symbolic link is created)

Another way  is to upgrade SVN client to latest SVN 1.8.xx which already handles http/https access.

Reasons behind this [2]
GnuTLS library is an alternative to OpenSSL. Most Subversion clients for Windows are built against OpenSSL and are not affected by this issue. While some Subversion packages (available mostly on Linux-based operating systems such as Ubuntu and Debian) are built against GnuTLS and are affected.
