System requirements

Ubuntu Core docs
#1

Ubuntu Core has been designed to have low system requirements and to run on a wide range of hardware, from embedded IoT devices to industrial computing.

Minimum requirements are flexible and are entirely dependent on device configuration, but they’re generally constrained to the following:

  • core18: 256MB RAM, 256MB storage
  • core20/22: 384MB RAM (512MB with UEFI Secure Boot for FDE), 512MB storage

Get in touch to discuss more constrained or specific requirements.

Pre-built images are available for various reference platforms, as listed below:

  • Raspberry Pi 2, 3, 4 and Compute Module 3/4
  • Intel NUC, generic x86 and x86 KVM

See Supported platforms for a list of systems Ubuntu Core officially supports, and for links to installable images for those systems.

#2

This has never been supported by Ubuntu since it uses ARMv6 hardware which Ubuntu never ran on …

The “Hardware/CPU” column is also wrong for the 1st gen Pi, it uses ARM1176JZF-S, not Cortex-A72

#3

Ah, great information - thank you! I’ll update the doc.

#4

also note that the core-20-pi is a universal image, the armhf variant works on pi2,pi3,cm3 and pi4 equally well (arm64 only for pi3,cm3 and pi4)

#5

Thanks for letting me know - I’ve updated the image links (I’ll update from pending to stable after the release).
