Comment 9 for bug 283155

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here.

update-manager should not break even if proxy setting are wrong. low priority because the user need to enter wrong settings in /etc/apt/apt.conf in order to trigger this bug. The cause if the change in Chris's config is another story.

Thanks for taking the time to make Ubuntu better!
