After add the repository http://qgis.org/debian and run
$ apt-get update
, before try QGIS install, I get the following message: http://qgis.org/debian/dists/vivid/main/binary-i386/Packages 403 Forbidden [IP: 188.8.131.52 80].
Obviously, this mean that I can not connect to the repository, but I can access it through web browser after answer a reCaptcha process. I figure out that QGIS servers are behind CloudFlare.
How can I proceed to install QGIS 2.14 via apt-get ?
