Sources

This section explain how to adjust the repositories list.

Ubuntu

Edit the sources.list

vim /etc/apt/sources.list

You need to enable:

• Ubuntu official repositories
• Backport - community repositories
• Ubuntu partners - commercial packages
• 3rd parties - from non-related providers

Your file should look like that:

##
## Ubuntu repositories
## Distros: 
##    ubuntu 13.10     => saucy  
##    ubuntu 14.04 LTS => trusty
##    ubuntu 16.04 LTS => xenial
##    Ubuntu 17.10 ==> Artful
##    Ubuntu 18.04 ==> Bionic Beaver

!! Don't forget to replace 'trusty' by the distribution name !!

Debian

Edit the sources.list

nano /etc/apt/sources.list

## Debian repositories
deb http://ftp.fr.debian.org/debian stable main contrib non-free
deb http://ftp.debian.org/debian/ jessie-updates main contrib non-free
deb http://security.debian.org/ jessie/updates main contrib non-free

sudo dpkg -i deb-multimedia-keyring_2015.6.1_all.deb

Take changes into account

sudo apt-get update && sudo apt-get upgrade

If you ever encountered some GPG errors, just import the "ubuntu-extras" key:

gpg --keyserver keyserver.ubuntu.com --recv 3E5C1192
gpg --export --armor  3E5C1192 | sudo apt-key add -
