How to determine a snap's dependencies

snapd
1

hello,

I am trying to figure out the dependencies (necessary snaps) that are installed before my actually queried snap is installed. Is there a way similar to command: snap info firefox that can provide list of snaps that will be installed along with firefox?

For now, there is no way to do that. You can only figure it out from the manifest of the snap.

This is a good start:

snap download firefox
unsquashfs firefox_*.snap meta/snap.yaml
grep -E '^base:|^    default-provider:' squashfs-root/meta/snap.yaml
base: core22
    default-provider: gtk-common-themes
    default-provider: gtk-common-themes
    default-provider: gtk-common-themes
    default-provider: gnome-42-2204

So if I snap install firefox, I’ll also get core22, gtk-common-themes and gnome-42-2204 (if I didn’t already have them).

Hope that helps.

hi all,

thanks this was useful, ideally it would have been better to fetch this without downloading the snap.

for context I’m trying to write python script for seeding snaps based on given array of snap names
