After updating the system, it can be seen that there are many services that are automatically turned off. Because the specific services from the source code for a particular kernel are stopped after updating the system. So it is necessary to turn off Auto-Update.
So those who want to disable or enable Auto-Update should follow the below commands.
sudo dpkg-reconfigure -plow unattended-upgrades
You can also open the following command below:
sudo nano /etc/apt/apt/.conf.d/20auto-upgrades.
You can disable specify 0 automatic updates:
APT::Periodic::Update-Package-List "0";
APT::Periodic::Unattended-Upgrade "0";
if you want in the future you can update manually:
sudo apt update
sudo apt upgrade
If you want automatic updates enabled and you receive all kinds of update notifications all the time, then follow the commands below.:
sudo nano /etc/apt/apt.conf.d/50unattended-upgrades
Specify the parameters:
Unattended-upgrade::Mail "test@technicalafnan.com";
//Unattended-upgrade::Mail::MailonlyOnError "true";
You can also prohibit package updates in this file.
Unattended-upgrade::Package-BlackList {
// "Vim";
// "Libc6";
// "Libc6-dev";
// "Libc6-i686";
};
If you have Auto-Update Enabled and check if it works follow the below command.:
sodo unattended-upgrades --dry-run --debug
Auto-Update logs are written in this file /var/log/unattended-upgrades/unattemded-upgrades.log
