Whereas Ubuntu Linux hasn’t supplied Flatpak help out-of-the-box because of their choice of utilizing their very own Snap app packaging/distribution format, Ubuntu flavors/spins have so far been in a position to pre-install Flatpak help in the event that they desired. Nonetheless, for the 23.04 “Lunar Lobster” cycle and transferring ahead, Ubuntu flavors will not be permitted to put in Flatpak packages by default.
Flatpak help for Ubuntu and its flavors will stay accessible within the Ubuntu archive so these wanting to put in Flatpak help can simply achieve this post-install.
This alteration going into impact with the 23.04 cycle is making it so no Ubuntu flavors may have Flatpak help put in by default / out-of-the-box: they’re purported to focus on Debian packages and Snaps for his or her out-of-the-box packaging help to align with Ubuntu.
From the weblog OMG Ubuntu:
Ubuntu builders have agreed to cease transport Flatpak, preinstalled Flatpak apps, and any plugins wanted to put in Flatpak apps by way of a GUI software program instrument within the default package deal set throughout all eight of Ubuntu’s official flavors, as of the upcoming Ubuntu 23.04 launch.
Ubuntu says the choice will ‘enhance the out-of-the-box Ubuntu expertise’ for brand new customers by making it clearer about what an “Ubuntu expertise” is….
So far as Ubuntu is anxious, solely deb and snap software program is intrinsic to the ‘Ubuntu expertise’, and that have now must be supplied in all places. Taste leads (apparently) agree, and have all agreed to reflect common Ubuntu by not providing Flatpak options of their default set up for future releases….
Flatpak won’t be uninstalled or eliminated when person makes the improve to Ubuntu 23.04 from a model the place Flatpak is already current.
