How is ubuntu doing

Do you want to upgrade? Follow our simple guide. Whether you want to configure a simple file server or build a fifty thousand-node cloud, you can rely on Ubuntu Server and its five years of guaranteed free upgrades. Ubuntu is the reference OS for OpenStack. Try Canonical OpenStack on a single machine or start building a production cloud on a cluster — just add servers. Ubuntu flavours offer a unique way to experience Ubuntu with different choices of default applications and settings, backed by the full Ubuntu archive for packages and updates.

More packages. Newer tools. All your open source, from cloud to edge. The HackerEarth Developer Survey. More than Linux. Security and compliance for the full stack. Secure your open source apps. Patch the full stack, from kernel to library and applications, for CVE compliance. Companies engage Canonical to drive down open source operating costs. Automate everything: multi-cloud operations, bare metal provisioning, edge clusters and IoT.

Most public cloud instances are Ubuntu, for performance and security. Operate private cloud the smart way — supported or fully managed. Charmed Kubernetes.

A snap can be strictly confined, which means that it operates in a secure box with only predefined points of access to the rest of the system. For third-party applications, this means that you will have a very high level of confidence that the app can only see appropriate data that you have provided to it.

Snaps can also be 'classic' which means that they behave more like debs, and can see everything on your system. You should make sure you have a high level of confidence in the publisher of any classic snap you install since a compromise or bad faith behaviour in that code is not confined to the app itself.

It is also common to consume Ubuntu as an image on a public cloud, or as a container. Ubuntu is published by Canonical on all major public clouds, and the latest image for each LTS version will always include security updates rolled up to at most two weeks ago. You may benefit from installing newer updates than that, but the base image you boot on the cloud should always be the current one from Canonical to ensure that it is broadly up to date and the number of updates needed for full security is minimal.

Canonical also publishes a set of images and containers that you can download for use with VMware or other local hypervisors and private cloud technologies. These images are also kept up to date, with the publication of rolled up security updated images on a regular cadence, and you should automate your use of the latest images to ensure consistent security coverage for your users.

Each release of Ubuntu is available in minimal configurations which have the fewest possible packages installed: available in the installer for Server, Desktop and as separate cloud images. There are also multiple flavours of desktop Ubuntu corresponding to a number of desktop GUI preferences.

All of these images are considered 'Classic' Ubuntu because they use debs as their base and may add snaps for specific packages or applications. The Ubuntu Core image is an all-snap edition of Ubuntu. It is unusual in that the base operating system itself is delivered as a snap; that makes it suitable for embedded appliances where all the possible apps that might need to be installed are available as strictly confined snaps.

Ubuntu Core is an appliance or embedded oriented edition of Ubuntu, not particularly comfortable for humans but highly reliable and secure for large-scale appliance deployments such as IoT and CPE in the telco world.

The debs in Ubuntu are categorised by whether they are considered part of the base system 'main' and 'restricted' are in the base and 'universe' and 'multiverse' are not and whether they are open source 'main' and 'universe' are, 'restricted' and 'multiverse' are not.

For each Ubuntu LTS release, Canonical maintains the Base Packages and provides security updates, including kernel livepatching, for a period of ten years. The lifecycle consists of an initial five-year maintenance period, during which maintenance updates are publicly available without an Ubuntu Advantage Subscription, and five years of Extended Security Maintenance ESM.

The full lifecycle is available with an Ubuntu Advantage subscription or a free personal subscription. Customers of Canonical often ask for an extended security maintenance commitment beyond the Ubuntu Base Packages such as the 'universe' software packages. You can contact us for more information. Canonical recommends that users and organisations upgrade to the latest LTS release or subscribe to Ubuntu Advantage for continued security coverage with ESM and kernel livepatching.

The Ubuntu Releases wiki has current information on previous and upcoming versions. Canonical maintains multiple kernel packages for each LTS version of Ubuntu, which serve different purposes.
