Canonical announces the release of Ubuntu 23.04. the Flatpak package format is no longer supported by default.

CTOnews.com, February 23, Canonical announced that since the release of Ubuntu 23.04, subsequent Ubuntu versions (including official flavor versions) do not support the Flatpak sandboxie installation package format by default.

There are already many GNU / Linux distributions that no longer provide support for the Flatpak format by default, and those who want to install the format can install Flatpak Runtime manually by following the tutorials provided by Canonical.

The words of Philipp Kewisch, the community engineering manager of CTOnews.com translation are as follows:

In the next version of Lunar Lobster, released in April 2023, the Flatpak package is no longer supported by default, and Flatpak applications are no longer integrated in the software center.

A special migration mechanism has been introduced into the flavor version of Ubuntu, so current users using Flatpak will not be affected by the upgrade.
