How to solve "502 internal error - server connection terminated" error?

When I try to install VirtualBox through Ubuntu Software Center it fails with the following errors:
Failed to fetch 502 internal error - server connection terminated [IP:

Why would that be? Has anyone else had difficulty with this? It has been going on for about 4 hours, so I doubt that it's site congestion.

The mirror you are using seems to create the problem.Just changing the server should solve the problem.But if you want to hit two birds in a go, follow these steps.
- Go to System settings > Software & updates(this can have a slightly different name) > Download from >other
- Select Select Best server
- Wait for the output and choose the server which suites you the best(generally the first one is best)
Alternately, you may just choose Main server, but note that it is very busy.
There seems to be an issue with the mirror you are using.
Go to System Settings > Software & Updates and set Download from: to a different server.
I'm also having the same issue right now and switched to the main servers and it worked.
Go to Settings -> Software & Updates -> Select "Main server" instead of server for Australia.
I'm thinking it must be a temporary issue, so you'll probably want to change that back in a day or two but that got it to work for me.
