Why did you create it manually? You should just edit the existing file. And this can be done via sudo dpkg-reconfigure unattended-upgrades
IIRC.
Debian operating system
Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
On my system that file is /etc/apt/apt.conf.d/20auto-upgrades
. You can read description of its parameters in comments in the /usr/lib/apt/apt.systemd.daily
script. It does not require unattended-upgrades
to work.
BTW I have unattended-upgrades
enabled for many years on all my systems, both desktops and servers, and it never caused any troubles when only stable repos are configured.
My system did not already have that 20auto-upgrades file. I went through the others in the directory and none seemed to contain those relevant lines. I just checked my other ubuntu system, which did have the 20auto-upgrades AND a 10periodic with the same lines, which is likely redundant.
Maybe just allow apt update specifically via the sudoers conf so you can cron job it to run without being prompted for user input, or just run it in cron as root.
