The substitute URI should be "https://mirrors.hydra.gnu.org". When using
such URI it works without an error.

My original question still holds though (why is an unresolvable
substitute-url able to bring the guix command down when at least one
working alternative substitute server exists? -- it should just warn
about it and push through).

Also, this error message is very cryptic; it didn't provided much that
would have helped me to realize about my error (wrong URI) earlier.
