The newest Ubuntu Linux, Impish Indri, is here

The important things first. An indri, also known as a babakoto, is a very large lemur. Ubuntu 10/21, mischievous Indri, is Canonical‘s newest Ubuntu Linux Publication. It is the short-term – nine months of support – predecessor of the company’s next Long-Term Support (LTS) version, Ubuntu 22.04.

Although we usually think of Ubuntu as a desktop Linux distribution, it is far more than that. Mark Shuttleworth, Founder of Canonical and Ubuntu, said, “Our goal is to bring Ubuntu to every corner of the business and to every place where developers want to innovate. This ranges from “the largest public clouds to the smallest devices, from [Nvidia] DGX server to Windows WSL [Windows Subsystem for Linux] Workstations is open source the springboard for new ideas and Ubuntu makes that springboard safe and consistent. “

On the desktop is the new Ubuntu standard interface GNOME 40. You can use the brand new GNOME 41, but that’s not the interface that 21.10 comes with. Still, some GNOME 41 apps like the Calendar app, GNOME Disk Utility, Eye of GNOME (aka Image Viewer), and GNOME System Monitor have made it into this new Ubuntu.

There are also some changes compared to Vanilla GNOME 40. The Ubuntu 21.10 version still comes with the convenient Ubuntu dock on the left side of your display. Ubuntu Dock now also comes with a permanent trash can icon, USB drive shortcuts and a separator between pinned and running apps. All in all, I like this new look.

There are, of course, other desktop options for the latest Ubuntu. The most mature of these seem to be to this day cinammon and the old one Ubuntu Unity interface that lives on as an independent project. Other desktops, such as KDE, Kubuntu, and Xfce, Xubuntu, will be released shortly on October 21st.

The standard desktop programs have also been updated. The new programs include the LibreOffice 7.2 Office suite that Thunderbird 91 E-mail client and the Firefox 92 Web browser. However, this is not your usual Firefox. While the old Firefox based on the Deb package is available, the standard is now containerized Snap Execution.

Why? Because that’s the way Mozilla, the parent company of Firefox, wanted it. the snapped version of Firefox is “jointly serviced by Mozilla” and the Ubuntu desktop team and published by Mozilla. “

Of course, not everyone, like the Linux Mint team, is happy about Snaps. Other users have complained that Snap-based programs are slower than their vanilla versions. At the moment the snaps are only the default setting in the main Ubuntu version and not in the various Ubuntu variants or downstream Linux distributions, such as mintbased on the Ubuntu Deb Repo version. When the next version of LTS, Ubuntu 22.4, hits the market, things may look different. Stay tuned.

This latest Ubuntu update includes many new tools for developers. That includes the brand new ones PHP 8 and GCC 11. The latter includes better support for static analysis. This will make life easier for low-level C and C ++ programmers.

Ubuntu 21.10 also offers a snap Apache Kassandra Package. With this distributed, open source NoSQL database, you can easily set up a Cassandra cluster.

For DevOps developers, Canonical made Ubuntu 21.10 trustworthy Open Container Initiative (OCI) Images available at Docker hub and Public Amazon ECR registry. In addition to the Ubuntu base image, Canonical also maintains a curated set of application images. The LTS Docker images are supported by Canonical for the full 10 year support lifetime of Ubuntu.

Canonical’s latest LTS Docker Images include Grafana, Prometheus, and NGINX. Apache Cassandra v4 is a new addition with real-time scraping, alerts, and improved Prometheus integration. Octopus, a caching proxy, and Bind9, a full-fledged DNS system, complete the portfolio of LTS Docker Images.

Under all of this, Ubuntu runs on the Linux 5.13 kernel. With that comes Kernel electric fence (KFENCE). This new high-performance run-time memory error detector for production environments has low overhead and still detects common memory errors. By default, Ubuntu 21.10 also randomizes the location of the kernel stack for each system call entry on both the amd64 and arm64 architectures, with minimal performance impact and increased protection against memory-based attacks.

Ubuntu is now friendlier than ever to Windows users. WSL 2.0 now supports graphical Ubuntu applications. Microsoft recently made WSL2 for Windows 11 more easily available as a separate app in the Microsoft Store. If you’re developing for both Windows and Linux, Ubuntu 21.10 is a natural solution.

If you want to try Ubuntu with Kubernetes Cloud-native projects, Canonical makes it as easy as falling out of a log. You can do that with MicroK8s. This program installs Kubernetes with a single command and forms a Kubernetes edge cluster with just two commands. MicroK8s now comes with the latest CNCF certified stable Kubernetes 1.22. It supports now too Kata container. With Kata, you can use lightweight virtual machines (VM) in a container runtime while providing higher workload security than traditional containers by using hardware virtualization technology for isolation.

Ubuntu 21.10 is available for download today for 64-bit systems. Older 32-bit PCs are no longer supported. For 32-bit Ubuntu that is still supported, you have to turn the clock back to Ubuntu 04/16/07.
