Server or a desktop computer? Are you working from a GUI or do you
want a command-line solution?

If you're working from a GUI, use the "Software & Updates" settings
dialog box to find the best/fastest mirror server.

The graphical method is described here:

If the errors come back, just do it again.

If you're on a server or want a permanent solution, you can edit your
/etc/sources.list file so that it looks for the fastest mirror every
time. I've done this on my home server. I am not sure if the time
saved offsets the search for the fastest, but it makes such problems
go away forever.

There are several methods, but the one described first here should work:
