That looks like gibberish to me. I think the script or repository or
some environment variable may be misconfigured, pasting together
several
git origin specs.

I've just looked at the logfiles for the previously successful build,
and the command appears identical:
invoking cd /home/gub/NewGub/gub/downloads/lilypond/git && git fetch
git://git.sv.gnu.org/lilypond.git
release/unstable:refs/heads/git.sv.gnu.org//lilypond.git/release/unstable
From git://git.sv.gnu.org/lilypond
* [new branch] release/unstable ->
git.sv.gnu.org//lilypond.git/release/unstable
invoking cd /home/gub/NewGub/gub/downloads/lilypond/git && git fetch
git://git.sv.gnu.org/lilypond.git
release/unstable:refs/heads/git.sv.gnu.org//lilypond.git/release/unstable
From git://git.sv.gnu.org/lilypond
* [new branch] release/unstable ->
git.sv.gnu.org//lilypond.git/release/unstable
(I've also attached the output as a text file, to avoid line-breaking
issues).
