Hey, I think something may have broken recently with the guix publish service. I run this on a server with very basic configuration, just setting the host, but I noticed recently that there were problems using the service. The following example is guix failing to download something from that server. Downloading http://beid.cbaines.net/nar/gzip/pwg84wqsniamc4vx9c7p06284i5rxiay-wxwidgets-3.0.3... wxwidgets-3.0.3 256KiB/s 00:00 | 16KiB transferred gzip: stdin: not in gzip format guix substitute: error: corrupt input while restoring '/gnu/store/pwg84wqsniamc4vx9c7p06284i5rxiay-wxwidgets-3.0.3' from #{read pipe}# wxwidgets-3.0.3 316KiB/s 00:00 | 48KiB transferredguix package: error: build failed: some substitutes for the outputs of derivation `/gnu/store/7f0zr1zgp6q1nyrsxf88qn003gr1w53b-wxwidgets-3.0.3.drv' failed (usually happens due to networking issues); try `--fallback' to build derivation from source I reverted the 4 recent changes [1], changed the service configuration to use (guix (current-guix)) and now it seems to be working again. I've had a look through the changes, I couldn't spot anything, but I think there could be a regression in these changes [1].
