You can automatically update the software packages of your system's operating system using the Ubuntu package unattended-upgrades.
The Ubuntu package unattended-upgrades is a useful tool for automatically updating software packages on an Ubuntu system.
It enables the regular updating of security patches and other important updates without the need for manual interaction.
Updates of on-premises systems
For on-premises systems, you as the administrator must ensure that the operating system packages (APT) are updated regularly. For edoc365 tenants, the edoc team takes care of regular updates.
If you run your Ubuntu system locally (on-premises), we recommend automatically updating the software packages with unattended-upgrades.
With the unattended-upgrades package, you can ensure that your systems are always supplied with the latest patches to improve the security and stability of the system. By automating the update process, potential vulnerabilities are eliminated promptly.
The unattended-upgrades configuration options allow you to customize various settings, such as setting specific times for the automatic updates or including or excluding specific packages.
By default, they are kept up to date: The SyncSystemState task is always used to check whether a configuration of unattended-upgrades exists (file /etc/apt/apt.conf.d/20auto-upgrades) and the following configuration is written:
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";
With this process, the package lists are automatically updated daily, and security updates are installed daily.
Restart after updating by "unattended upgrades"
The default configuration only installs security updates and not normal package updates. A necessary restart of the Ubuntu system is not performed automatically.
Please perform regular updates or at least restart regularly the Ubuntu system yourself.
