Realized my version of i3 is 4.7.2 and that the sur5r repository wasn't working for me. I'm using xubuntu 14.04 LTS
Here's what I see with apt-get update: Ign http://debian.sur5r.net -c InRelease Ign http://debian.sur5r.net -c Release.gpg Ign http://debian.sur5r.net -c Release Err http://debian.sur5r.net -c/-s) i386 Packages 404 Not Found [IP: 217.8.49.41 80] Err http://debian.sur5r.net -c/universe i386 Packages 404 Not Found [IP: 217.8.49.41 80] Ign http://debian.sur5r.net -c/-s) Translation-en_US Ign http://debian.sur5r.net -c/-s) Translation-en Ign http://debian.sur5r.net -c/universe Translation-en_US Ign http://debian.sur5r.net -c/universe Translation-en W: Failed to fetch http://debian.sur5r.net/i3/dists/-c/-s)/binary-i386/Packages 404 Not Found [IP: 217.8.49.41 80] W: Failed to fetch http://debian.sur5r.net/i3/dists/-c/universe/binary-i386/Packages 404 Not Found [IP: 217.8.49.41 80] E: Some index files failed to download. They have been ignored, or old ones used instead. And in my /etc/apt/sources.list file I have: deb http://debian.sur5r.net/i3/ -c -s) universe I also tried directly copying "deb http://debian.sur5r.net/i3/ $(lsb_release -c -s) universe" right into sources.list and am still getting 404's in my sudo apt-get update. Any info or suggestions would be appreciated. Thanks!
