Guix, The binary tarball and Hurd qcow2 links on , which resolve to and respectively, return 502. Here's why: 2020-11-18T17:31:24 GET /download/1450 Uncaught exception in fiber ##f: In ice-9/boot-9.scm: 1669:16 0 (raise-exception _ #:continuable? _) ice-9/boot-9.scm:1669:16: In procedure raise-exception: In procedure open-file: No such file or directory: "/gnu/store/vd5y7hmvgqc1hwmqyiwqa171r0iz1wib-hurd-barebones.qcow2" The file really is gone. It seems that Cuirass is no longer creating sufficient GC roots. I vaguely remember some changes to image GC'ing being discussed but not what (if anything) changed. Thanks to zimoun for pointing out the broken links. Kind regards, T G-R
