Ubuntu 21.10 "Impish Indri" arrives with updates, new installer and more

The new version of Ubuntu 21.10 "Impish Indri" has already been released after several months of development and few days of freezing that served for the final tests and the correction of errors.

In this new version of the distribution transitioned to using GTK4 and the GNOME 40 desktop, in which the interface has been significantly modernized. Activities Overview virtual desktops are configured in landscape orientation and are displayed in a continuous loop from left to right.

On every desk that displayed in overview mode clearly shows available windows, that move and scale dynamically through user interaction. It provides a seamless transition between the program list and virtual desktops. Better organization of work with multiple monitors. GNOME Shell provides a GPU for rendering shaders.

Another change is the new completely lightweight version of Yaru used in Ubuntu, along with which a completely dark option is also provided (dark headers, dark backgrounds, and dark controls). Support for the old combined theme (dark headers, light background, and light controls) has been discontinued due to lack of GTK4 capability to define different background and text colors for the title and main window, which does not guarantee that all GTK applications will work correctly when using the combined theme.

In the installation part, we can find the new installer for Ubuntu Desktop that has been proposed implemented in the form of a plugin on top of the Curtin low-level installer, which is already used in the default Subiquity installer on Ubuntu Server. The new installer for Ubuntu Desktop is written in Dart and uses the Flutter framework to build a user interface.

The new installer has been designed with the modern Ubuntu desktop in mind and is designed to provide a consistent installation process across the entire Ubuntu product line. Three modes are offered: "Repair Installation" to reinstall all available packages on the system without changing the configuration, "Try Ubuntu" to familiarize yourself with the Live Mode distribution kit, and "Install Ubuntu" to install the distribution kit on the disc.

Another novelty that stands out is that the ability to use a desktop session based on the Wayland protocol was provided in environments with controllers NVIDIA.

While for the sound part in PulseAudio the support for Bluetooth has been significantly expanded, since in this new version the A2DP LDAC and AptX codecs were added, integrated support for the HFP (Hands-Free Profile) profile, which made it possible to improve the sound quality.

As well there were changes in the handling of packages, for made some changes to use the zstd algorithm to compress deb packets, which will almost double the speed of package installation, at the cost of a small increase in its size (~ 6%). Support for using zstd has been around in apt and dpkg since Ubuntu 18.04, but it has not been used to compress packages.

Of the other changes that stand out in this new version:

  • By default, the nftables packet filter is enabled: To maintain backward compatibility, the iptables-nft package is available, which provides utilities with the same command line syntax as in iptables, but translates the resulting rules into code byte nf_tables.
  • Linux kernel 5.13 has been used
  • Updated versions of programs, including PulseAudio 15.0, BlueZ 5.60, NetworkManager 1.32.10, LibreOffice 7.2.1, Firefox 92, and Thunderbird 91.1.1.
  • The Firefox browser has defaulted to instant package delivery, accompanied by Mozilla employees (the ability to install a deb package is retained, but is now an option).

    Hello. I have a question, among the other distributions that Linux has, could this be considered the best of the moment or is there another that surpasses it?
