[Koha] Problem cloning using git

Hi, I'm experimenting a problem with git clone: $ git clone git://git.koha-community.org/koha-git kohaclone Cloning into kohaclone... fatal: The remote end hung up unexpectedly $ git clone http://git.koha-community.org/koha-git kohaclone Cloning into kohaclone... fatal: http://git.koha-community.org/koha-git/info/refs not found: did you run git update-server-info on the server? Is it my fault or the server is down? Thanks. Stefano
