In Debian Edu, we automatically search for error: in the installation
log to detect errors during installation.  When PXE installing, I get
this one:

  Jun 28 23:18:29 main-menu[555]: (process:2840): wget: server returned
    error: HTTP/1.0 404 Not Found

It is a bogus error message that is creating noise and confusion in
the Debian Edu test installation.

I've tried to track down where it come from, and as far as I
understand from the log it must originate from choose-mirror.

This is the relevant log fragment:

The URLs in the log seem to work, so I do not understand why wget is
complaining.  Is there some other wget calls that are not reported to
the log?

The only wget calls I find in choose-mirror do not throw away error
messages.  Perhaps they should?  If so, this untested patch should
implement it:

debian/changelog

  * Throw away stderr when calling wget, to avoid getting bogus error
    messages in the installation log.
