Here you can download the official Ubuntu 21.10 “Impish Indri” ISO for free.
Ubuntu 21.10, codenamed Impish Indri, was released on 14 October 2021. It uses Linux kernel 5.13, which introduces rudimentary support for Apple M1 chips, FreeSync HDMI support for AMD GPUs, a new “Landlock” security module and support for several new hardware.
This release transitions from GNOME 3.38 to GNOME 40, which introduces a horizontal workspace switcher and an improved Activities Overview design. The Ubuntu Dock remains vertically placed on the left of the screen and now features separators between pinned and running applications, a persistent trash can icon and USB drive shortcuts. After logging in, the user will be shown the desktop instead of the Activities Overview. Despite Ubuntu 21.10 shipping with GNOME 40, a few GNOME 41 apps are available. A Firefox Snap is now installed by default on Ubuntu 21.10 instead of the deb package, which remained available. Furthermore, the Nvidia proprietary drivers now support Wayland sessions. The default Yaru theme was also updated with new icons and Zstd compression was enabled in the main archive, making installations faster.
