I had this bug occur today when trying to run evince after an upgrade. The message told me to run the command:
gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache But this doesn't work because it needs to be done as root and because the full path to the command should be specified (it is even more confusing as command-not-found gdk-pixbuf-query-loaders or apt-cache search gdk-pixbuf-query-loaders return nothing). Specifically: sudo /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders | sudo tee /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache The error message should be clarified accordingly (and there's also a question of why this command wasn't run during the upgrade process in the first place). -- Antoine Amarilli
