As Junio mentioned, this does seem like the issue that 05e9515
(upload-pack: send keepalive packets during pack computation,
2013-09-08) tries to fix. The server is quiet for a long period while
preparing the pack, and something in the network stack thinks the
connection has timed out and kills it.

One way you can check this is by running:

  time git clone -q git://kernel.ubuntu.com/ubuntu/linux.git

If it's a network timeout, it will die consistently at some nice round
number. In this case, I just ran that command twice, and it died both
times at just a hair over 2 minutes.  So that is probably what is going
on.  There's no proxy on my end, so presumably there is some front-end
reverse proxying happening on the server end, and it has a 2-minute

The keepalive patch is not in any released version yet, but we have been
running it in production at GitHub for a few weeks. You may want to file
a support request with the Ubuntu folks asking to pick up the patch, or
to increase the timeouts on their proxies.
