Canonical announced the release of Ubuntu 21.10, codenamed Impish Indri, shortly after the release candidate. The developers state that the latest release is designed for cloud-native developers and artificial intelligence and machine learning innovators across the desktop, devices, and cloud. Ubuntu 21.10 is not an LTS (Long-Term Support), it is a short-term release, which means it will be supported for 9 months.

The Impish Indri comes with PHP 8 and GCC 11, which include full support for static analysis to improve developer security awareness. The latest version also comes with GNOME 40 desktop, which brings dynamic workspaces and touchpad gestures. Ubuntu 21.10 also supports graphical applications on Windows Subsystem for Linux for Windows developers, allowing them to use Ubuntu desktop applications without modification.
Canonical also announced that the Ubuntu 21.10 OCI image is available on Docker Hub and Amazon ECR Public Registry. Canonical’s latest LTS Docker Images include Grafana, Prometheus, and NGINX.

MicroK8s enables the installation of Kubernetes with a single command and forms the Kubernetes edge cluster in two commands. It also offers CNCF-certified Kubernetes 1.22in the stable channel. Kata containers are now activated in MicroK8s, a new way to run containers with lightweight virtualization to improve deployment security. MicroK8s for IBM Z support is also available for beta testing.
With the Ubuntu 21.10 release, Canonical offers Apache Cassandra packaged as a snap. It allows DataOps teams to set up a Cassandra cluster.
KFENCE
Ubuntu 21.10 introduces support for Kernel Electric Fence, or KFENCE for short, with Kernel 5.13. KFENCE is a new run-time memory error detector capable of detecting most of the common memory errors. The latest version of Ubuntu will randomize the memory location of the kernel stack at each system-call entry as default.
Additional details about KFENCE
Impish Indri is the final interim release before Canonical’s next Ubuntu long-term support, which is due to be released in April of 2022. Ubuntu 21.10 allows developers to future-proof their work for the next LTS, which will be supported for at least 10 years. Mark Shuttleworth, CEO of Canonical said:
“As open source becomes the new default, we aim to bring Ubuntu to all the corners of the enterprise and all the places developers want to innovate. From the biggest public clouds to the tiniest devices, from DGX servers to Windows WSL workstations, open source is the springboard for new ideas and Ubuntu makes that springboard safe, secure and consistent.”
