Ubuntu 18.04 LTS is moving out of standard support in April 2023.
Why choose Ubuntu Core?
Imagine a world where every device is trustworthy. We designed every aspect of Ubuntu Core to create the most secure embedded Linux ever, with a 10y LTS commitment.
For smart use cases
Get Core. Get snaps. Get going.
Keep a bad app in its box
You trust your developers, but anybody can make a mistake. We created and integrated a whole new armoury of Linux security capabilities to ensure applications stay confined to their own data.
10 year security update commitment
That's a decade of sleeping soundly
Ubuntu Core gets 10 years of Canonical maintenance. Your smallest devices are now as secure as your servers. No other embedded Linux comes close.
Minimal core, minimal risk, minimal bugs
We stripped Ubuntu Core down to bare essentials
Fewer packages to attack, fewer bugs to fix, fewer forced changes. We reduced the OS to reduce the attack surface. That leaves more disk for your applications and data.
We check for known weaknesses or risks
Automatic scanning of all snaps for vulnerable libraries and problematic code keeps the Ubuntu Core ecosystem clean and healthy.
Protect sensitive customer data
Lock data to devices with hardware keys in TPM or TEE, and unlock disks for your system software only, to block a physical attack on sensitive information.
Decide which updates go to your devices
Over the air updates guarantee secure software in any location. As a device manufacturer or a snap publisher, you decide which updates are signed, certified and delivered to your devices.
Preserve data, and rollback on error automatically
Your power supply may not be reliable. Your devices will be. Resilience to adversity saves money and reputations. Rely on Ubuntu Core to deliver your software updates safely.
Snapshots for application data
Standard mechanisms for application data management.
Every device has apps which keep track of critical data. We make sure you can manage the data which matters to you, consistently, across all your Ubuntu Core devices. Backup and restore anything, anywhere.
Backup boot paths
Low-level updates preserve the prior boot path.
When you have to update the kernel or the operating system you want to know you can go back if needed. Ubuntu Core keeps the last working boot so you always have a safety net.

Tamper-resistant and hardened
You need to know your software is pristine; not just for installation, but for the lifetime of the device.
Immutable packages and persistent digital signatures mean Ubuntu Core can verify any software component at any time, to guard against corruption and attack.
Built for business
Absolute control over every device in the building.
Enterprises gain complete control over every app on every device on the network, regardless of manufacturer. Know exactly which kernel version and which apps are running.

One platform from cloud to device
Bring apps from Ubuntu Server to Ubuntu Core
Snaps run on Ubuntu Server, Desktop and Core. One platform, one process. Your developer workstation, your build farm, your cloud and servers all use snaps. Your appliances can too, with extra security.
Embedded Linux is easy on Ubuntu
We handle the board, you handle the apps
No bad BSPs. No maintenance nightmares. No integration delays. Just develop on Ubuntu. Embedded, but not as you knew it.
Deploy to devices as fast as the cloud
Continuous deployment on devices
Put your devices on rails for rapid iteration with continuous deployment pipelines, beta testing and canary updates. Featuring Travis integration and a multi-arch build service.
Harness all things open source
From GitHub to Ubuntu Core in minutes.
Ride the open source wave, or build your own community. Open source projects default to Ubuntu, so building is easy.
