I checked the download-page and the links there are to the same server
(alpha.gnu.org). Because you see a "Network unreachable" instead of a
"file not found", I suppose your network does not permit
FTP-connections (i.e. port 21 being blocked).

As Garbor mentioned, the link to the signature is also on the download
page. Here is the direct link for x86_64:

https://alpha.gnu.org/gnu/guix/guix-binary-0.15.0.x86_64-linux.tar.xz.sig

Hope that helps,
