Comment 6 for bug 446552

Does this also fix the following problem with '/usr/bin/do-release-upgrade' which i have with jaunty?

The python script tries to download something like http://changelogs.ubuntu.com/meta-release, but fails because of not handling proxy authentification. The problematic code is in /usr/share/pyshared/UpdateManager/Core/MetaRelease.py around line 251. It generates
407: ('Proxy Authentication Required', 'You must authenticate with this proxy before proceeding.'),
