First issues first. An Indri, aka a Babakoto, is an overly huge lemur. Ubuntu 21.10, Impish Indri, is Canonical’s newest Ubuntu Linux unlock. It is the temporary — 9 months of make stronger — predecessor to the corporate’s subsequent long-term make stronger (LTS) model, Ubuntu 22.04.
As such, whilst we typically recall to mind Ubuntu as a desktop Linux distribution, it is excess of that. As Mark Shuttleworth, Canonical and Ubuntu’s founder says, “We goal to deliver Ubuntu to the entire corners of the endeavor and the entire puts builders need to innovate. That is going from “the largest public clouds to the tiniest gadgets, from [Nvidia] DGX servers to Home windows WSL [Windows Subsystem for Linux] workstations, open supply is the springboard for brand new concepts and Ubuntu makes that springboard secure, protected and constant.”
At the desktop, the brand new Ubuntu default interface is GNOME 40. Whilst you’ll use the brand-spanking-new GNOME 41, that isn’t the interface 21.10 comes with. Nonetheless, a couple of GNOME 41 apps comparable to Calendar app, GNOME Disk Application, Eye of GNOME (aka Symbol Viewer), and GNOME Gadget Observe have made it into this new Ubuntu.
As well as, there are some adjustments from vanilla GNOME 40. The Ubuntu 21.10 model nonetheless comes with the at hand Ubuntu Dock for your show’s left facet. Ubuntu Dock additionally now comes with a continual trash can icon, USB power shortcuts, and a separator between pinned and operating apps. All-in-all I love this new glance.
There are, in fact, different desktop possible choices for the newest Ubuntu. Essentially the most mature of those up to now seem to be Cinnamon and the previous Ubuntu Solidarity interface, which lives on as an impartial challenge. Different desktops, comparable to KDE, Kubuntu, and Xfce, Xubuntu, shall be out for 21.10 in a while.
The default desktop techniques have additionally noticed updates. New techniques come with the LibreOffice 7.2 administrative center suite, the Thunderbird 91 email shopper, and the Firefox 92 internet browser. This isn’t the standard Firefox although. Whilst the old-school Deb-package-based Firefox is to be had, the default is now a containerized Snap model.
Why? As a result of that is the means Mozilla, Firefox’s father or mother corporate, sought after it. The snapped model of Firefox is being “collectively maintained by means of Mozilla and the Ubuntu desktop staff, and printed by means of Mozilla.”
OF route, no longer everybody, such because the Linux Mint staff, is excited about the use of snaps. Different customers have complained that snap-based techniques are slower than their vanilla variations. For now, the snaps are best the default in the principle Ubuntu unlock and no longer within the more than a few Ubuntu flavors nor downstream Linux distros, comparable to Mint, that depend at the Ubuntu Deb repo model. When the following LTS model, Ubuntu 22.four, arrives, it can be a special tale. Keep tuned.
This present Ubuntu replace comes with many new gear for builders. Those come with the all-new PHP eight and GCC 11. The latter contains higher make stronger for static research. This may increasingly make existence more straightforward for low-level C and C++ programmers.
Ubuntu 21.10 additionally gives a snap Apache Cassandra equipment. With this open-source NoSQL allotted database, you’ll simply arrange a Cassandra cluster.
For DevOps builders, Canonical has made devoted Ubuntu 21.10 Open Container Initiative (OCI) photographs to be had from Docker Hub and Amazon ECR Public Registry. But even so the Ubuntu base symbol, Canonical additionally maintains a curated set of utility photographs. The LTS Docker Pictures are subsidized by means of Canonical for Ubuntu’s complete, 10-year make stronger existence.
The most recent LTS Docker Pictures from Canonical come with Grafana, Prometheus, and NGINX. Apache Cassandra v4 is a brand new addition, with real-time scraping, indicators, and progressed Prometheus integration. Squid, a caching proxy, and Bind9, a full-featured DNS formula, also are becoming a member of the portfolio of LTS Docker Pictures.
Beneath all of it, Ubuntu runs at the Linux five.13 kernel. With this comes Kernel Electrical Fence (KFENCE). This new high-performance run-time reminiscence error detector for manufacturing environments comes with low overhead whilst nonetheless detecting not unusual reminiscence mistakes. Through default, Ubuntu 21.10 additionally randomizes the kernel stack’s reminiscence location at every system-call access on each the amd64 and arm64 architectures with a minimal affect on functionality and an building up in coverage towards memory-based assaults.
Ubuntu is now friendlier to Home windows customers than ever. WSL 2.zero, now helps Ubuntu graphical programs. Microsoft just lately made WSL2 for Home windows 11 extra simply to be had as a separate app within the Microsoft Retailer. If you happen to broaden for each Home windows and Linux, Ubuntu 21.10 is a herbal have compatibility.
If you wish to have to check out Ubuntu with Kubernetes cloud-native initiatives, Canonical makes it as simple as falling off a log. They may be able to do this with MicroK8s. This program installs Kubernetes with a unmarried command and paperwork a Kubernetes edge cluster with simply two instructions. MicroK8s now comes with the newest CNCF-certified solid Kubernetes 1.22. It additionally now helps Kata packing containers. Kata permits you to use light-weight digital machines (VM) in a container runtime whilst offering more potent workload safety than standard packing containers by means of the use of hardware virtualization era for isolation.
Ubuntu 21.10 is to be had for obtain nowadays for 64-bit techniques. Older 32-bit PCs are not supported. For still-supported 32-bit Ubuntu, you wish to have to show again the clock to Ubuntu 16.04.07.
