# Fix curl/gnutls SSLv3 on Ubuntu 14.04
#
# The curl version on Ubuntu 14.04 Trusty Tahr has a bug (through gnutls) in
# its SSLv3 support. This also affects git.
#
# This script will rollback curl, libcurl3, and libcurl3-gnutls to the version in Ubuntu 12.04.
# Unfortionately, it does not seem to be possible to automatically update for security patches
# so you must manually check for curl updates at the url below.
