in github this software is archived with no more support. So I guess there is another piece of software that allow to manage graphically the software installations, and not only snaps ...

I have been tempted by ubuntu-kylin-software-center but it's kind of chinese only. Which software as closest functionality to software-boutique to be a good replacement of software-boutique on Noble (24.04) ?

As an alternative app store, you can install GNOME software with

sudo apt install gnome-software
  • After some test I definitively recommend using gnome-software, which is usable by installing it with apt and it has two plugins, one for snap and one for flatpak packages, which gives it a real advantage. This is also the case for the Discover software which is nice too, and got the same plugins, but I tend to prefer gnome based stuff.
