As usual, didn't get any answer here :-( Found the solution myself. The problem is about the System->Preferences->Network Proxy It seems that the no_proxy environment variable is badly set: it has a trailing comma (',') that it should not have. Removing such comma from the environment variable made wget work. <div class="gmail_quote">On Tue, Aug 17, 2010 at 2:27 PM, Massimiliano Ziccardi <<a href="mailto:massimiliano.ziccardi@gmail.com">massimiliano.ziccardi@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"><div class="im"><blockquote style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;" class="gmail_quote"> If you don't mind using a gui, try gwget ('sudo apt-get install gwget' - it will be in Applications|Internet|gwget afterwards), then: Edit|Preferences|Network.

I have a script that always worked but, after I've upgraded my ubuntu to the latest release, it stopped working. Noone here knows how to fix that? It seems wget now ignores proxy settings ! Should I fire a bug ? Thanks in advance, Massimiliano </blockquote></div>
