Programmatically disable apt unattended upgrades

How can I programmatically/script disable apt unattended upgrades? Running Ubuntu 16.04.

Several methods exists:

Method One

1. Turn off automatic upgrade by reconfiguring unattended-upgrades in the /etc/apt/apt.conf.d/50unattended-upgrades file:

   • Comment out individual lines in the Unattended-Upgrade::Allowed-Origins set of rule:-

     Unattended-Upgrade::Allowed-Origins {
         "${distro_id}:${distro_codename}-security";
         //      "${distro_id}:${distro_codename}-updates";
         //      "${distro_id}:${distro_codename}-proposed";
         //      "${distro_id}:${distro_codename}-backports";
     };
     

2. Selectively disable auto-update on a package level, by adding package names to "Unattened-Upgrade:Package-Blacklist" set of rules:

   Unattended-Upgrade::Package-Blacklist {
       //      "vim";
       //      "libc6";
   };
   

Method Two

1. Disable auto-update system-wide from the /etc/apt/apt.conf.d/10periodic file:

   • sudo nano /etc/apt/apt.conf.d/10periodic:

     APT::Periodic::Update-Package-Lists "1";
     APT::Periodic::Download-Upgradeable-Packages "0";
     APT::Periodic::AutocleanInterval "0";
     APT::Periodic::Unattended-Upgrade "0"; <--- line of interest, should be "0"
     

Method Three:

Go to Ubuntu Software Center, Edit --> Software Sources, choose Never for Automatically check for update

You can just remove unattended upgrades which takes a dpkg lock:

$ sudo apt-get remove unattended-upgrades

Or just disable it via configuration:

$ sudo vim /etc/apt/apt.conf.d/10periodic

and make sure to have this line with zero value:

APT::Periodic::Unattended-Upgrade "0";

Easier and less fragile method (I think less fragile than apt remove unattended-upgrades) is:

cp  /usr/share/unattended-upgrades/20auto-upgrades-disabled  /etc/apt/apt.conf.d/

I've verified it by looking at /var/log/unattended-upgrades/unattended-upgrades.log
