My bug https://gitlab.gnome.org/GNOME/gdk- pixbuf/-/issues/157#note_804913and was closed after a brief discussion.
Could this be fixed in Ubuntu with a post-install script? One would expect thumbnails in nautilus to simply work. Most people won't search the help pages and then dig into the configs and will be frustrated. This used to work in previous Ubuntu versions, so it is a regression. ** Bug watch added: gitlab.gnome.org/GNOME/gdk-pixbuf/-/issues #157 https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/issues/157 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gdk-pixbuf in Ubuntu. https://bugs.launchpad.net/bugs/1879488 Title: raw NEF thumbnails not processed Status in gdk-pixbuf package in Ubuntu: Confirmed Bug description: Raw NEF thumbnails are not displayed in Nautilus.
