Ubuntu is one of the most popular Linux distributions based on Debian. It is composed of open source code. One of the versions released based on Ubuntu is the Server version. This operating system is supported for cloud computing with OpenStack support. The default Ubuntu desktop is GNOME since version 17.10. Ubuntu is released every six months, and Long Term Support (LTS) releases every two years.    As of April 22, 2021, the most recent long-term support release is 20.04 (“Focal Fossa”), which is supported through 2025 through public support and 2030 as a paid option. The latest standard release is 04/21 (“Hirsute Hippo”), which is supported for nine months.
Since the first version of Ubuntu 6.06 was released, every fourth release has received long-term support. It introduces new hardware updates, security fixes, and updates to the Ubuntu (cloud computing infrastructure) stack. The first LTS releases were supported for three years on desktops and five years on servers; Starting with Ubuntu 12.04 LTS, desktop support for LTS releases has also been increased to five years. LTS releases receive regular point releases with new hardware support and integration of all updates published in the series to date.
This article will talk about new updates for this distribution, namely Ubuntu 21.10. New features, capabilities, and benefits of this version will be described. It is also worth noting that we recommend that you constantly use more modern versions of the distribution, in order to get acquainted with all the updates and try new features!
Ubuntu 21.10: Impish Indri
Impish Indri – will be a kind of code word, or the same meaningful phrase that will characterize this version of the distribution. The main features of this release are that the Short Term Support Release, which is Ubuntu 21.10, will be supported for 9 months. This support will focus on major bug fixes and major bug fixes, critical security patches, and major new application releases. Support ends in July 2022 and it is recommended to “upgrade” to Ubuntu 22.04 LTS. The official release date for this release is October 14, 2021. This version will be available from late October – early November 2021 on Hostry servers
Ubuntu 21.10: New Features
So what new updates can we expect from Canonical? The company plans to release Ubuntu 21.10 with a new installer based on Flutter. Work on the new Ubuntu installer is progressing slowly and is far from being “functional.” It will be interesting to see if development of the new installer starts by 21.10, otherwise the new installer is unlikely to officially debut until 22.10.
Ubuntu 21.10 currently uses GNOME 40 as the default desktop, although Ubuntu 21.10 is expected to ship with GNOME 41, due out in September.
Ubuntu still uses the Ubuntu Dock on the left side of the screen. Canonical developers have contributed to GNOME Shell, making the Ubuntu Dock work well with horizontal workspaces and the new horizontal application launcher.
As the default theme, the Ubuntu development team decided to set Yaru Light as the default theme in Impish, citing issues with maintaining the current “mixed” versions. There is no word on whether the Shell UI will also switch back to light (it was switched to dark in the previous release); while the GNOME Shell theme is still dark in Impish, citing problems with maintaining current “mixed” versions. There is no word on whether the Shell UI will also switch back to light (it was switched to dark in the previous release); while GNOME Shell theme is still dark. Below will be presented the main updates that can be used in the new version of this distribution:
- Most importantly, the new Linux Kernel 5.14
- New Ubuntu branding
- Zstd compression for packages, which will help you a lot when installing various programs quickly
- New installer for Flutter
- New variety of wallpapers
The default theme for Ubuntu 20.10 is the same as 21.04 – the default Yaru, except that on 21.04 the default skin theme is switched to Yaru Dark. This means that even if your system has a light theme by default, notifications, message bar and taskbar will use a dark theme.
There are many updates to this version of Ubuntu, and with that the Ubuntu team is in a hurry to implement all the new features intended for this release. Hence, this should give them time to fully master the new features ahead of the release of Ubuntu 22.04 LTS. Between Gnome 40, Linux 5.14 and the new desktop installer, Ubuntu 21.10 is one of the biggest releases in recent years. It will be interesting to see how the Ubuntu team adopts the new look and feel of GNOME along with other changes.
If you have previously used Ubuntu heavily, then most likely you have come across the fact that the standard Ubuntu theme is a mixed theme. It has a dark window bar (or application title bar) and everything else follows the light theme pattern. Due to conflicts between Ubuntu and GNOME default theme colors and the lack of a theming API for GTK (and the Gnome shell), it is already problematic to customize and work with the Ubuntu desktop theme.
Moreover, GTK 3 and GTK 4 do not support having a separate background color for the title bar from the rest of the window. Hence, it is difficult to maintain a bug-free implementation for every GTK application. And that’s the reason why the Yaru community design team recently suggested removing the mixed theme. The Ubuntu team agreed with this decision and the changes were merged. You no longer have to look for a mixed theme in Ubuntu 21.10, just dark and light themes as your option. In other words, “Yaru” will be a light theme, and “Yaru dark” will be a dark theme when using GNOME Tweaks. “Yaru-light” will no longer be available.
With all that has been described in this short article regarding the new version of Ubuntu, we recommend that you keep updating the version of your distribution kit. It doesn’t matter if you are working on your own server or on the desktop version. The new distribution opens up new possibilities for you and shows you new heights for aspiration. If some special and specific version of the distribution kit is not in the recipes of our servers, installation of an ISO image is always available.
