Bug#862560: debian-live: GNOME Software in Debian Live lists only installed packages

[intrigeri]

Hi,

[adding Debian GNOME Maintainers in the loop, as it might be a bug in
GNOME Software / PackageKit that affects any Debian+GNOME first boot
experience, rather than something specific to how we build Debian Live
systems]

>    * What led up to the situation?
> Launch GNOME Software in Debian Live.
> Only "Installed" tab show packages.
> The "All" tab only show "Editor's Picks" on the top, the rest is blank.

>    * What exactly did you do (or not do) that was effective (or ineffective)?
> I launch the command "sudo apt update".

>    * What was the outcome of this action?
> After launch this command, the "All" tab is still blank.

>    * What outcome did you expect instead?
> Show all packages.

FWIW on a Fedora 26 live system:

1. After logging into the GNOME session, GNOME Software / packagekitd
   start downloading stuff from the Internet (presumably package
   indices but I didn't investigate).

2. If I start GNOME Software, then I see a progress bar that says
   "Software catalog is being loaded" or "Software catalog is being
   downloaded" (depending on when exactly I start it), and eventually
   a list of available packages.

… i.e. the right thing happens, so the good news is that it's feasible :)

I don't know if they do something special to make this work in Fedora,
or if the PackageKit support for APT is lagging behind, or if we do
something special in our Live images that breaks this.

I wonder if the first boot experience after installation is affected
by the same problem. Does anyone know by heart? Otherwise, maybe syl
would be happy to try?

Cheers,
