When #PopOS' Pop!_Shop does not display apps, that is typically because it cannot reload its appstream app data. The fix is to [ensure `flatpak` works](https://flatpak.org/setup/Pop!_OS/) and to update `pkcon` to avoid the need of restarting the system: ```bash sudo apt install flatpak flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo sudo apt install packagekit-tools sudo pkcon get-updates sudo pkcon update ```
