The Fedora buildbots seem to have problems currently to clone the gnulib Git repository.
>From the logs:
./bootstrap: getting gnulib files...
Cloning into 'gnulib'...
command timed out: 1200 seconds without output running [b'nice', b'-n', b'19', b'./bootstrap'], attempting to kill
process killed by signal 9
program finished with exit code -1
Is "git" working correctly on that worker?
I think there are some network issues. I cannot even clone octave (on a different computer but the same network as buildbots).
