I asked this question on stackoverflow already, but someone pointed me to this community (that I didn't know about before) - so here it is again:

I want to install Linux Tails. I already added ppa:tails-team/tails-installer to my sources, but when my Ubuntu Software Center tries to download the repository information, I get this error:

W:Failed to fetch
404 Not Found , W:Failed to fetch
404 Not Found , E:Some index files failed to download. They have been
ignored, or old ones used instead.

I am using ubuntu 14.04 LTS. If you follow the link up to tails-installer/ubuntu/dists/ you can see that "trusty" is missing.

Any idea on what to do? Should I just wait?

You can't install the tails installer on Ubuntu 14.04 :/

In this step, you will install Tails Installer, a program designed specifically for installing Tails. Tails Installer is available in:

  • Debian 8 (Jessie) or later in the backports repository
  • Ubuntu 15.10 (Wily) or later in a PPA (Personal Package Archive)

from tails installation doc

You'll need to install Tails using GNOME Disks
