How to enable silent automatic updates for any repository?(http://askubuntu.com/q/87849/417607)

Procedure:

Follow the steps below:

1. Install unattended-upgrade sudo apt-get install unattended-upgrades

2. Discover it works only for security updates from official repos. by default.

Problem:

To make it work for all repos, you need to add each source to the config file manually. This might become hassle each time you install a new software on your machine. It may even lead to duplicate or unwanted entries or just a mere waste of time!!!

Solution:

Run this simple code.

how to run this?

• Check repositories to add:

$ python unattended_upgrades_repos.py
Add repos:
"Ubuntu:xenial";
"LP-PPA-kubuntu-ppa-backports:xenial";
"LP-PPA-tuxonice:xenial";
"LP-PPA-webupd8team-sublime-text-3:xenial";

Skipping files due to not present origin or suite. Or origin being a url.:
packagecloud.io_slacktechnologies_slack_debian_dists_jessie_InRelease
tiliado.eu_nuvolaplayer_repository_deb_dists_xenial_InRelease

• Now edit /etc/apt/apt.conf.d/50unattended-upgrades to include them:

// Automatically upgrade packages from these (origin:archive) pairs
Unattended-Upgrade::Allowed-Origins {
	"${distro_id}:${distro_codename}-security";
	"${distro_id}:${distro_codename}-updates";
	"${distro_id}:${distro_codename}-proposed";
	"${distro_id}:${distro_codename}-backports";
  "Ubuntu:xenial";
  "LP-PPA-kubuntu-ppa-backports:xenial";
  "LP-PPA-tuxonice:xenial";
  "LP-PPA-webupd8team-sublime-text-3:xenial";
};
....
....

• Check to see if they are included:

$ sudo unattended-upgrade --dry-run --debug
