Today, I downloaded http://cdimage.debian.org/cdimage/ports/latest/hurd-i386/debian-hurd.img.tar.xz thrice via wget (302 redirected to http://caesar.ftp.acc.umu.se/cdimage/ports/10.0/hurd-i386/debian-hurd.img.tar.xz each time). But I couldn't decompress it:
philipp@notebook5:/tmp/Hurd$ LANG=C tar xJf debian-hurd.img.tar.xz xz: (stdin): File format not recognized tar: Child returned status 1 tar: Error is not recoverable: exiting now on the other hand, https://cdimage.debian.org/cdimage/ports/latest/hurd-i386/debian-hurd.img.gz works fine for me.
