Ah, this is the key point for the whole conversation since it will require classic confinement for the foreseeable future and thus far we’ve not allowed snaps that require use of the package management commands are problematic for a snap that is distributed via the Global store.
@pedronis - at this point, the current guidelines dictate that the request be denied. I will point out that the application isn’t meant to install arbitrary applications and instead only manage upgrades. We can’t enforce that at this time (though in the medium to long term, this may become possible with some future apparmor work), but it is a slightly different angle than other requests that use package managers. At this point, I am going to leave this request alone unless you feel otherwise.
@eloy.garcia.pca - thank you for working through this with us. If you have more details for @pedronis, feel free to add them.
