dbus.exceptions.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name is not activatable

[dodgekaze]

I successfully installed Hamster by following the instructions provided in the Readme file. I observed that Hamster is no longer accessible via Snap and DNF, so I utilized Flatpak instead. To install Hamster, I executed the command: flatpak install flathub org.gnome.Hamster.

However, after completing the installation, I encountered an error when I attempted to launch Hamster using the command: flatpak run org.gnome.Hamster. The error message I received is as follows:

(org.gnome.Hamster.GUI:2): Gtk-WARNING **: 10:35:51.836: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.

Try running the service manually,

❯ flatpak run --command=/app/libexec/hamster/hamster-service org.gnome.Hamster

and then try to run the main app from a separated terminal.
