Okay, I've gone down the rabbit hole with this one. It's possible this is 2 separate issues.
I tested 3 scenarios: Scenario 1 - Performed a clean Ubuntu Server install (interactive), and installed ubuntu-desktop-minimal post-deployment. After rebooting, the 50appstream config is present, and I installed snap-store and gnome-software. Neither snap-store nor gnome-software showed any .deb packages. Only snaps. I tried re-installing appstream and forcing a refresh of the cache, but still no .deb packages shown. Nothing I have tried in this install has been able to fix the issue. Scenario 2 - I performed a clean install using our automated install image (/var/log/installer contents attached) WITHOUT our appstream config reinstall script that I shared previously. After deployment, ubuntu-desktop-minimal is already installed, and 50appstream config is MISSING (see attachment). Both snap-store and gnome-software only show snaps. No .deb packages. Next, I ran the appstream re-install script I shared previously and rebooted the machine. After the reboot, gnome-software correctly shows .deb packages. However, snap-store is still only showing snaps!!! Scenario 3 - I performed a clean install using our automated install image (/var/log/installer contents attached), this time including our appstream config reinstall script. After the deployment, 50appstream config is PRESENT. Both snap-store and gnome-software work correctly and show both snaps and .deb packages. The varying behaviour between all 3 has completely blown my mind. I really don't know what is the cause of the issue, and potentially this is even 2 separate issues, since in Scenario 1, neither snap-store nor gnome-software work correctly. ** Attachment added: "installer logs for Scenario 1" https://bugs.launchpad.net/ubuntu/+source/appstream/+bug/1983112/+attachment/5607134/+files/scenario_1_installer.zip -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to appstream in Ubuntu. https://bugs.launchpad.net/bugs/1983112 Title: Appstream does not install config file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/appstream/+bug/1983112/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
