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

[William Hua]

Ah, makes sense, thanks for the explanation!

count is zero or close to zero)

How do we define close to zero? On my system, there are 5 apps that
always seem to have AS_APP_STATE_UNKNOWN:

gs_plugin_appstream_startup: 8: 'UEFI-dummy-dev0' ('UEFI Updates'): 0
gs_plugin_appstream_startup: 9: 'com.via.VL811.firmware' ('VL811 Firmware'): 0
gs_plugin_appstream_startup: 10: 'com.via.VL811+.firmware' ('VL811+ Firmware'): 0
gs_plugin_appstream_startup: 11: 'com.via.VL812.firmware' ('VL812 Firmware'): 0
gs_plugin_appstream_startup: 12: 'com.via.VL812_B2.firmware' ('VL812 B2 Firmware'): 0

So I'm not really sure how to precisely define when an apt update is
required or not.

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

Status in gnome-software package in Ubuntu:
  In Progress
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.
