Ubuntu – Cannot disable automatic update checks on Kubuntu 18.04

18.04kubuntuupdates

I am trying to disable automatic update checks on Kubuntu 18.04. I have unticked the option to check for updates daily by using Settings -> Configure Software Sources -> Updates in muon but the system keeps checking for updates on every startup.

The contents of /etc/apt/apt.conf.d/10periodic are

APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";
APT::Periodic::Unattended-Upgrade "0";

Is there anything else that has to be done in order to stop those automatic checks completely?

Best Answer

At my 18.04.1 installation there was no file /etc/apt/apt.conf.d/10periodic.

After a short search I found:

/etc/apt/apt.conf.d/20auto-upgrades

There I could disable my auto-updates. Maybe you could also have a look there for your solution.

I just zero-ed the values; so my content of /etc/apt/apt.conf.d/20auto-upgrades is now:

APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Unattended-Upgrade "0";
APT::Periodic::Download-Upgradeable-Packages "0";
