Why are there some packages in the Software application but not in apt?

  • 772

I recently moved from Debian to Ubuntu, I usually used apt to install package (and don't want to use the software center as apt it let me know which package are installed as dependencies).

But I already found something I wasn't expecting:
some package like atom and discord are available in the software center but not in apt, isn't the software center a graphic interface for apt? does it use something else?

package-management apt gnome-software

    You have just discovered "snap" packages, they are deployed by "snappy" package management system built by Canonical Ltd. (the Ubuntu company).

    Snaps are containerised software packages that are simple to create and install. They auto-update and are safe to run.

    The Software application also contains snaps, in fact

    Some applications are available in both formats. In such a case in Ubuntu Software the snap will be listed first. (source)

  2. isn't the software center a graphic interface for apt

    No. Ubuntu software center also supports snap installation. See the snapcraft store. Discord on command line would be

    sudo snap install discord

    and atom would be

    sudo snap install --classic atom
