Failure trying to clone Elpa

[N. Jackson]

Following the instructions at https://savannah.gnu.org/projects/emacs,

  $ git clone git://git.sv.gnu.org/emacs/elpa
  Cloning into 'elpa'...
  remote: Counting objects: 132670, done.
  remote: Compressing objects: 100% (43403/43403), done.
  error: object 2699d230e3b592ae42506d7b5c969a7ac6a4593c: zeroPaddedFilemode: 
contains zero-padded file modes
  fatal: Error in object
  fatal: index-pack failed

The following also fail in the same way:

  $ git clone git://git.savannah.gnu.org/emacs/elpa.git

and

  $ git clone https://git.savannah.gnu.org/git/emacs/elpa.git

.

Is this a problem in Elpa or is it just user incompetence? Thanks.
