[Koha] Problem cloning using git

[Stefano Bargioni]

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
