I use proxy to connect to the Internet. I am trying to upgrade to 12.10. The problem is that some(nearly all) packages are downloaded but some 3 Mb data is not downloading, due to which the upgradation aborts reporting a forbidden error. These are some files related to gnome-games and facebook integration. Facebook is blocked on the proxy server which i am using, so i guess the error appears due to that. I want to ask if there is any way i can skip downloading the last 3 Mb packages(which i don't need) so that my upgradation continues to Ubuntu 12.10? This is the error i am getting:
