# WARNING: this script is outdated. The latest Duplicity requires python 3.7 
# which EL7 doesn't have. I suggest you switch back to the duplicity from the repo.
# Keeping this script here for reference; there may be some info here that is still useful.

# The version of duplicity in the EL repo is way too old.
# This installs the latest duplicity, including dependencies.
# This script has been tested on Centos 7.
# Just run it as root, sit back and enjoy:
#   wget https://raw.githubusercontent.com/onnozweers/scripts/master/install-duplicity
#   chmod 700 install-duplicity 
#   ./install-duplicity
