`mirror://` is not a real URL schema; it's used by Guix as a substitute for writing out the various mirror URLs of large projects like GNOME. Here's the definition of Gnome's mirror URLs: --- guix/download.scm (define %mirrors ;; Mirror lists used when `mirror://' URLs are passed. (let* (…) `(… (gnome "https://download.gnome.org/"; "http://ftp.gnome.org/pub/GNOME/";) …))) --- So the correct URL would be one of these two; by the way, I think that `mirror://` URL might be wrong, as the `tracker` directories only contain `3.4`, not `3.4.2`: https://download.gnome.org/sources/tracker/3.4/tracker-3.4.2.tar.xz http://ftp.gnome.org/pub/GNOME/sources/tracker/3.4/tracker-3.4.2.tar.xz Both of these work when passed to `guix download`.
