A fresh installation of Flatpak on Fedora 42 is unable to find or install standard packages from the official Flathub remote when using the command-line interface. The flatpak search and flatpak install commands consistently fail with an error of "Nothing matches..." for common packages like the KDE Platform and its themes. This issue persists even after a complete purge of Flatpak (dnf remove flatpak), manual deletion of all data (/var/lib/flatpak and ~/.local/share/flatpak), and a fresh reinstallation of both Flatpak and the Flathub remote. Network connectivity to Flathub is confirmed to be working correctly via curl. The problem appears to be specific to the command-line client's inability to correctly parse or access the full Flathub repository index. Reproducible: Always Steps to Reproduce: Perform a full removal of flatpak and its data: sudo dnf remove flatpak sudo rm -rf /var/lib/flatpak rm -rf ~/.local/share/flatpak Reinstall flatpak: sudo dnf install flatpak Add the official Flathub remote: flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo Attempt to install a standard KDE component: flatpak install flathub org.kde.PlatformTheme.breeze Actual Results: The command fails with the error: error: Nothing matches org.kde.PlatformTheme.breeze in remote flathub Expected Results: The command should find the package and proceed with the installation. Additional Information: Flatpak Version: 1.16.1-1.fc42 The issue was successfully bypassed by reinstalling gnome-software and using its graphical interface to search for and install the desired Flatpak application (AudioTube). The GNOME Software application was able to correctly identify, download, and install the application and all of its dependencies (including the KDE Platform and Breeze theme) from Flathub without issue. This strongly suggests the bug is located within the command-line components of Flatpak on Fedora. Show thinking
