[Bug 1766542] Re: Installation blocks when the machine is behind a proxy server

[Steve Langasek]

Robert, can you please provide complete steps to reproduce this bug?  My
understanding from discussion elsewhere that this is specific to oem-
config mode; is that correct?

If your network is incorrectly configured and you have a route to the
Internet but traffic is dropped, it is expected that an initial
connection to the apt mirror will have to hit a tcp connection timeout
(by default, ~128 seconds); so that might qualify as "several minutes".
What behavior are you seeing that is "too long", and how long do you
expect this to take?

  Installation blocks when the machine is behind a proxy server

Bug description:
  When the machine is behind a proxy server, the installation will block
  for a while (several minutes) to retrieve the package lists. The
  timeouts are too long and makes user feels the machine may have some
  problems.

  The symptom is similar with bug #14599, but it seems the apt-setup
  module was rewritten.

  Another method to trigger this issue is to make the machine cannot
  access to the Internet, for instance: a wrong gateway.
