Oh, that's right, Manjaro, don't know why I asked what system in the other email! ‘pacman -Qi mailcap’ will query for information on that package and show the upstream URL is https://pagure.io/mailcap. Pagure is like a SourceForge or GitLab and that installation is Fedora's, despite the misleading domain name: https://pagure.io/about/. Fedora took Red Hat's source. I've access to a Manjaro system. After a ‘sudo -i pacman -Syu’ to ensure its packages are up to date, I see $ pacman -Q file file 5.40-2 $ file -i /usr/share/mathjax2/extensions/a11y/invalid_keypress.mp3 /usr/share/mathjax2/extensions/a11y/invalid_keypress.mp3: audio/mpegapplication/octet-stream; charset=binary $ b2sum -l32 /usr/share/mathjax2/extensions/a11y/invalid_keypress.mp3 c7d7c71d /usr/share/mathjax2/extensions/a11y/invalid_keypress.mp3 So the bug is there. Does it report ‘audio/mpegapplication/octet-stream’ for lots of your MP3 files? Back home, on an out-of-date Arch Linux, after copying that MP3 file to here: $ pacman -Q file file 5.37-2 $ file -i invalid_keypress.mp3 invalid_keypress.mp3: audio/mpeg; charset=binary On both machines, ‘pacman -Qi file’ reports that package's upstream is https://www.darwinsys.com/file/. -- Cheers, Ralph.
