Instructions for GNU/Debian installation

Add the repository

Or add the file in /etc/apt/sources.list.d/.
sudo wget -q -O/etc/apt/sources.list.d/
To add EFL Universe repository, add this line to your /etc/apt/sources.list:

Or add the file in /etc/apt/sources.list.d/ and remove comments.

Install the GnuPG key

Install the signing key.

sudo wget -q -O/etc/apt/trusted.gpg.d/altern-deb-jessie-stable.gpg


If you want, you can use https instead of http.
  1. Install apt-transport-https package: sudo aptitude install apt-transport-https.

Run aptitude update.
You should now be able to install the Altern-DEB packages you want with aptitude (or dselect, or apt-get as well...).
