Canonical unveils Ubuntu 21.10 – TechRepublic

The purpose is to reinforce the developer expertise wherever they work, the corporate mentioned.

Ubuntu 21.10 provides GCC 11, PHP 8, Gnome 40, WSLg, and a variety of Ubuntu Docker container photographs, based on Rob Gibbon, product supervisor at Canonical. Moreover, “there’s Apache Cassandra, packaged each as a Docker container picture and as a snap, giving DataOps groups a brand new choice for constructing and working data-intensive Cassandra clusters.”

One other characteristic is the brand new GCC 11, which Canonical referred to as the de facto C/C++ compiler. Improved static code evaluation capabilities have been added to robotically detect vulnerabilities and assist builders achieve higher code safety insights earlier within the improvement cycle, the corporate mentioned.

Safety updates

Ubuntu 21.10 additionally comes with a raft of security measures, Gibbon mentioned. “Kernel 5.13 brings important safety enhancements to the Ubuntu platform, together with Kernel Electrical Fence (KFENCE), a light-weight runtime reminiscence error detector designed to be used on manufacturing programs,” he mentioned.

It additionally comes with Landlock—a compulsory entry management system designed for straightforward administration, and kernel stack offset randomization throughout system calls, which goals to guard towards sure types of privilege escalation exploit with minimal overhead, Gibbons mentioned.

“Moreover, 21.10 ships with unprivileged Berkely Packet Filter (BPF) entry disabled by default, though directors can nonetheless allow this characteristic if required,” he mentioned.

Designed for Ubuntu builders wherever they’re

Ubuntu 21.10 brings the PHP 8 and GCC 11 together with full assist for static evaluation, Canonical mentioned. This goals to enhance safety consciousness in low-level programming.

With Gnome 40 desktop customers achieve dynamic workspaces and touchpad gestures. Mozilla’s new Firefox snap is designed to enhance safety and ensures entry to each the newest and the prolonged assist launch variations of the browser, Canonical mentioned. The very same variations of the browser can be found on a number of completely different variations of Ubuntu, which goals to simplify enterprise developer platform administration, the corporate mentioned.

Over the past yr, the variety of snaps printed within the retailer has grown by 25%, and the snap retailer now serves over 10 million programs every day.

Home windows builders are being supplied out-of-the-box assist for graphical purposes on Home windows Subsystem for Linux, so Ubuntu desktop purposes do not require modification.

Cloud native from the sting to the mainframe

Trendy improvement practices more and more rely upon containerized photographs however assuring picture provenance of open supply software program could be difficult, Canonical famous. Utility builders need constant, reliable container photographs from a dependable supply, the corporate mentioned. So Canonical mentioned it has made the Ubuntu 21.10 OCI picture out there on Docker Hub and Amazon ECR Public Registry. 

Alongside the Ubuntu base picture, Canonical maintains a curated set of utility photographs. LTS Docker Photographs present commitments for compliance and safety updates, that are backed by Canonical for the total lifetime of Ubuntu, not less than 10 years, the corporate mentioned.

Additional, the newest LTS Docker Photographs from Canonical embrace Grafana, Prometheus and NGINX. Apache Cassandra v4 is a brand new addition, with real-time scraping, alerts and improved Prometheus integration, based on Canonical. Additionally becoming a member of the portfolio of LTS Docker Photographs are Squid, a caching proxy, and Bind9, a full-featured DNS system, the corporate mentioned.

MicroK8s installs Kubernetes with a single command and kinds a Kubernetes edge cluster in simply two instructions. MicroK8s now comes with the newest CNCF-certified Kubernetes 1.22 within the secure channel. MicroK8s assist for IBM Z is designed to offer customers cloud-native devops with the steadiness and safety of the mainframe, Canonical mentioned.

There’s additionally a give attention to synthetic intelligence and machine studying workloads. With Ubuntu 21.10, Canonical provides Apache Cassandra packaged as a snap, enabling DataOps groups to arrange a Cassandra cluster, based on the corporate.

Run-time reminiscence error detection

With kernel 5.13, Ubuntu 21.10 provides assist for Kernel Electrical Fence, a brand new run-time reminiscence error detector designed for manufacturing environments. KFENCE is designed to maintain the overhead low whereas detecting the most typical reminiscence errors.

“Enabled by default, Ubuntu 21.10 will randomize the reminiscence location of the kernel stack at every system-call entry on each the amd64 and arm64 architectures with a minimal impression on efficiency,” Canonical mentioned.

Ubuntu 21.10 Impish Indri is the ultimate interim launch earlier than the following Ubuntu Lengthy Time period Help due for launch in April 2022. Ubuntu 21.10 shall be supported not less than till 2032, the corporate mentioned.

“As open supply turns into the brand new default, we goal to convey Ubuntu to all of the corners of the enterprise and all of the locations builders need to innovate,” mentioned Mark Shuttleworth, founder and CEO of Canonical, in an announcement. “From the most important public clouds to the tiniest gadgets, from DGX servers to Home windows WSL workstations, open supply is the springboard for brand spanking new concepts and Ubuntu makes that springboard secure, safe and constant.”
