Ubuntu Core 20 Released For IoT Devices With Secure Boot By Default


Canonical, the company behind the most popular Ubuntu operating system, is already preparing for the next Ubuntu 21.04 “Hirsute Hippo,” which is scheduled to be released on April 22, 2021.

Meanwhile, after Ubuntu Core 18 was released in 2019, Canonical has now made its Ubuntu Core 20 for IoT generally available to the public.

Ubuntu Core 20 is a minimal and containerized version of the Ubuntu 20.04 ‘Focal Fossa’ LTS specifically designed for IoT devices and embedded systems.

It aims to secure Linux for IoT by providing features such as secure boot, full disk encryption, and secure device recovery.

Unlike the regular Ubuntu release, which uses the traditional Debian package system, this Ubuntu Core almost relies entirely on the universal package management system called snap, developed by Canonical.

For better security and avoid damage from any compromised application, all snaps on Ubuntu Core devices are strictly confined and isolated.

Speaking of the latest Ubuntu Core 20, it comes with several security updates and important new features.

For instance, it has added secure boot by default with hardware-backed full disk encryption to protect the privacy and guarantee confidentiality from physical attackers.

Among the other enhancements, this is what Ubuntu Core 20 has included:

  • New recovery and reinstall mode
  • Recovery mode menu and chooser
  • Raspberry Pi support (both ARMv7 and ARM v8)
  • Initial MAAS and cloud-init support

If you want to learn more about Ubuntu Core, you can read the official documentation or register for the webinar scheduled for 24 February 2021.

Lastly, if you want to get your hands on Ubuntu Core 20, download the images available here for x86_64 and ARM hardware with ten years of support.
