The spacebar preview feature for GNOME Sushi is being fixed in Ubuntu 26.04. GNOME Sushi is a file preview utility for the GNOME desktop environment, allowing users to select a file in the Nautilus file manager and press the spacebar to display a floating preview window. This tool provides quick previews for various file types, including images, videos, audio files, PDFs, and plain text. Although not preinstalled in Ubuntu, many users install it to facilitate file identification. This upcoming fix addresses the core preview functionality for the next long-term support release of Ubuntu.
