That bug is really annoying. And it appears to have been there for a long time. But not affecting everyone for some strange reason. I tried to upgrade from Jaunty to Karmic today and all proxy settings were ignored, I had them in apt, update-manager and in the enrivonment just fine, nothing worked. In the end I edited utils.py as suggested by Serge van Ginderachter and this made it finally working! The strange thing is, when I did the last upgrade from Intrepid to Jaunty the whole update process worked just fine without messing with any settings. So probably something changed (again?) with Jaunty?
