Comment 2 for bug 512401

I'm having exactly the same problem. Running Ubuntu 10.04. It sits on the last line (see the bottom of this post) for a number of minutes and then gives up with "Error: Plug-in file not found (server returned 404 or similar error). Error code: [Errno 104] Connection reset by peer".

Has your server been up and down lately??
