Cannot disable automatic update checks on Kubuntu 18.04
Solution 1:
To disable automatic upgrades in Kubuntu 18.04, run:
$ sudo dpkg-reconfigure --priority=low unattended-upgrades
and when prompted Automatically download and install stable updates?, choose "No" and follow the remaining prompts. To see the status of automatic upgrades, run:
$ apt-config dump APT::Periodic::Unattended-Upgrade
The value produced (an integer) means how often to update automatically, in days. A zero value means disabled.
Solution 2:
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";
