sudo nano /and so forth/apt/apt.conf.d/20auto-upgrades

with the next contents:

APT::Periodic::Replace-Bundle-Lists "1";
APT::Periodic::Unattended-Improve "1";

Aside from it there are two extra origins one is to fetch and set up the Proposed Updates and the opposite is for Backports updates.

If you wish to allow them, take away // given in entrance of them. Nevertheless, first, know what they’re.
