Canonical posted a tweet on the X (Twitter) platform stating that due to the introduction of crowdsourced user translations from a third-party tool in Ubuntu 23.10, which resulted in the discovery of some hate speech, the image has been withdrawn, and work is underway to re-tool and recompile the ISO image.

Ubuntu Discourse’s additional content is as follows:

"Shortly after the release, we discovered hate speech from a malicious contributor in a specific set of translations of the Ubuntu desktop installer UI and took immediate action.

We will re-release the ISO download links once we have replaced the problematic translations.

It's worth noting that these translations are not part of the Ubuntu Archive, and we believe that the incident only included translations made available through the third-party translation tools we use for some of our applications.

Affected images that have been removed include Ubuntu Desktop 23.10, Ubuntu Budgie 23.10, and Ubuntu Desktop daily images."

The new “App Center” app center front-end supports installation via Snap and Deb formats and is built on Flutter. : Ubuntu announced in 2021 that it would build apps using Flutterby default.

The old Ubuntu Software / Snap Store was often criticized by users for poor performance, high memory usage and inconsistent behaviour, and the redeveloped App Center is expected to alleviate these pain points.

The new App Center homepage is clean and logically organized, with eye-catching banners to attract interest when scrolling, and the new App Center also allows you to manage your Snap apps within the app itself.

The “Activities” label in the upper left corner of the GNOME 45 desktop environment has been replaced by an animated workspace indicator. Users can click and slide to switch to different workspaces. The currently selected workspace will be confirmed in the shape of a pill.

The picture is as follows, the original picture is a bit shaky:

The GNOME 45 desktop environment should improve the Quick Setting menu. On compatible keyboards, the backlight of some keyboards can be controlled by the keyboard instead of the system.

The new version also optimizes the settings app, introduces a new “details” widget, adjusts the position of the clock and calendar, and more.

Some new features of the GNOME 45 desktop environment, such as application magnifiers and screenshots, did not appear in Ubuntu 23.10. Ubuntu 23.10 is scheduled to be officially released on October 12, 2023.

After months of testing, however, the decision has been officially dropped, and the Ubuntu 23.10 (Mantic Minotaur) and Ubuntu 24.04 LTS distributions will still use the DEB-based print stack by default.

The team has delayed the effective date and plans to switch to the snap version CUPS print stack by default in the Ubuntu 24.10 release.

Ubuntu 23.10 developer version has already added snap version CUPS print stack and just in the process of testing found a lot of problems

A brief list of the following:

• The snap version of the CUPS print stack is not yet ready to be embedded in the desktop distribution.
• The snap version of the CUPS print stack does not work properly in some flavours.
• GNOME Control Center needs to adapt its UI to the snap version of the CUPS print stack.
• D-Bus sessions need improved support

Snap is a new generation of Linux package management tools from Canoncial that aims to standardize the package format across all Linux distributions so that it can be used “once packaged, always used”.

Snap is now available on several Linux distributions, including Ubuntu, Fedora, Mint, etc. Snap applications are sandboxed, and the system implements security features by restricting access to resources.

Snap has the following advantages over the traditional deb format:

• Dependency management: Snap packages have all the runtime and dependency libraries built-in, so they can run on any version of the Ubuntu distribution without having to worry about dependencies.
• Version Control: The Snap format allows developers to package different versions of software into different Snap packages, which allows users to install different versions of software at the same time without interfering with each other. This is also very useful for developers as they can test different versions of software in different Snap packages.
• Security: The Snap format provides a sandboxing mechanism that increases the security of the system by limiting the access rights of the software to the system. This mechanism makes it safer for users to install and use software without having to worry about the software jeopardizing the security of the system.
• Easy Maintenance: The Snap format allows developers to automatically update software to the latest version, which makes it easier for users to keep their software current.

Citing the media report, Maya OS is close to Windows in terms of user interface and interactive experience, which will speed up the migration of its staff.

In addition, Maya OS comes with built-in anti-malware and anti-virus software called Chakravyuh, which creates a virtual layer between the user and the Internet, preventing hackers from accessing sensitive data.

With reports that India has been hit by a number of major security incidents over the past few years, including a nuclear power plant security incident in 2019, India’s defence ministry believes it can reduce malware attacks after switching to a homegrown, Ubuntu-based version.

Reports claim that Indian software companies and academic institutions have collaborated to test and improve the operating system, and after a six-month trial, the Indian Navy has approved its use and the Army and Air Force are currently evaluating it.

Canonical announced in February this year, the purchase of an Ubuntu Pro subscription, using the code name Jammy Jellyfish Ubuntu 22.04 LTS users to provide real-time Ubuntu kernel.

The Ubuntu real-time kernel is built on the out-of-tree PREEMPT_RT patched Linux kernel and is available exclusively for x86_64 and AArch64 hardware.

With it, Canonical hopes to further support the use of Ubuntu in telecoms / 5G equipment and other industrial systems with low-latency requirements, delivering performance, guaranteed ultra-low latency and security for critical infrastructure.

Canonical has now optimized the Ubuntu real-time kernel for Intel CPUs, providing end-to-end security and reliability for enterprises to leverage the power of Linux for a wide range of deployments across telecoms workloads, factory-floor automation systems and life-saving medical devices.

Canonical said its optimized real-time Ubuntu kernel for Intel SoCs will drive innovation, simplify operations, improve efficiency and deliver optimal productivity.

Intel TSN support ensures processing and network prioritization for time-sensitive applications and workloads, while Intel TCC support prioritizes cache, memory and network access for real-time workloads.
