Snap and Flatpak

Robert,

I haven't been able to figure this out..

I know that you need services running in order to install snap packages, but chroot doesn't run services.

One user pointed out that installation was as simple as...

    1. Copy the snap package into the /snap directory
    2. Copy the snap's *.desktop file into /usr/share/applications or into /etc/skel/.local/usr/share/applications

(See https://bugs.launchpad.net/cubic/+bug/1843257/comments/8).

However, I haven't tried this, and am not sure it would work.

Note that on Cubic's terminal page, you can copy files by `cd`-ing into the target directory and then dragging the file(s) onto the window .

(I suspect there must be an "official" way of deploying snap packages, perhaps by including them in the ISO's `pool` directory and adding a corresponding preseed configuration???)

Looks like snap does not work in a container like the one Cubic uses.

However, I was able to successfully install a flatpack apps in Cubic...

    $ apt install gnome-software-plugin-flatpak
    $ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
    $ flatpak install --assumeyes flathub org.glimpse_editor.Glimpse

I got the following message, but the application works fine after booting into the custom ISO:
    "Warning: While trying to apply extra data: apply_extra script failed, exit status 256"

I do have a question: regarding the above commands, are they verbatim commands that actually do the downloading, or are they just templates?

The first two are verbatim.
The last one is an example which installs an image editor. Of course, you could replace "org.glimpse_editor.Glimpse" with another application.
