Hello Linux Geeksters. In this article I will show you how to install the F.lux indicator on Ubuntu 13.04 Raring Ringtail via command line interface.
Actually, it is very simple, all you have to do is this:
Step 1. Add these lines to your /etc/apt/sources.list:
deb http://ppa.launchpad.net/kilian/f.lux/ubuntu raring main
deb-src http://ppa.launchpad.net/kilian/f.lux/ubuntu raring main
Step 2. Update the repository index:
$ sudo apt-get update
Step 3. Install F.lux:
$ sudo apt-get install fluxgui
This is it. Enjoy.
After performing
$ sudo apt-get update
I got:
W: Failed to fetch http://ppa.launchpad.net/kilian/f.lux/ubuntu/dists/raring/main/source/Sources 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/kilian/f.lux/ubuntu/dists/raring/main/binary-amd64/Packages 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/kilian/f.lux/ubuntu/dists/raring/main/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
How should I fix that?
Same here, haven’t been able to find the solution. Perhaps it’s no longer available?
I followed a different approach which also worked:
sudo add-apt-repository ppa:kilian/f.lux
sudo apt-get update
sudo apt-get install fluxgui
Less error prone than mucking about directly with source.list and the PPA PGP keys.
