Steps To Update Ubuntu

Ubuntu System Updates

Keeping the system updated is vital before starting anything on your system. This will prevent people to use known vulnerabilities to enter in your system.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get autoremove
sudo apt-get autoclean

Enable Automatic Security Updates On Ubuntu

Enable automatic updates can be crucial for your server security. It is very important to stay up to date.

You can install the unattended-upgrades by using this command:

sudo apt-get install unattended-upgrades

To enable it, run:

sudo dpkg-reconfigure -plow unattended-upgrades

This will create the file /etc/apt/apt.conf.d/20auto-upgrades with the following contents:

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";

Customize Automatic Updates On Ubuntu

You can customize the automatic updates if you prefer. For example, you can get notifications when a security update is completed.

To enable ONLY security updates, please change the code to look like this:

  // Automatically upgrade packages from these (origin:archive) pairs
  Unattended-Upgrade::Allowed-Origins {
  //  "${distro_id}:${distro_codename}-updates";
  //  "${distro_id}:${distro_codename}-proposed";
  //  "${distro_id}:${distro_codename}-backports";

To get notification by email, update the following line with your email address:

//Unattended-Upgrade::Mail "";
