[Bug 1554023] Re: Perform an apt update if there is no appstream available

[William Hua]

Just trying to think through what the correct approach is here. Is there
a reason why are we going through appstream to get the list of packages
instead of looking directly in /var/lib/apt/lists and
/var/lib/dpkg/status for the package info? The apt plugin is already
somewhat doing this (I'm assuming apt/dpkg still properly update
/var/lib/* after installation without needing an update, but I'm not
sure).

Title:
  Perform an apt update if there is no appstream available

Status in gnome-software package in Ubuntu:
  New
Status in livecd-rootfs package in Ubuntu:
  Fix Released

Bug description:
  appstream's IndexTarget doesn't take effect until the first 'apt
  update' after it is installed. This means you get no installed
  software after first installing g-s until you update again.

  I tried to ask apt's developers if they could see a way to fix this
  but on first reply they deny there is a problem at all.

  So I think we have to workaround the problem somehow. First strawman:
  have gnome-software do an 'update' on first launch if it finds no
  appstream metadata and /etc/apt/apt.conf.d/50appstream is installed.

  We also need to fix this in livecd-rootfs for new installs. I guess
  there we can add a hook to do an update as part of the build.
