I have Ubuntu 8.04 and I am trying to use "update manager" to upgrade to 8.10. The upgrade fails because of some problem related to network/internet setting. The error I get is discussed and a solution by hyperion is posted at: https://answers.launchpad.net/ubuntu/+question/50648
hyperion is referring to the settings in System-->Preferences-->Network Proxy
I have the option "Direct internet connection" selected. Hyperion says that Ubuntu will upgrade if I choose "Manual proxy configuration". The problem with this option is that I would have to fill in a lot of details like HTTP proxy, Secure HTTP proxy, Port (8080?) and I dont know any of this.
I have a AT&T DSL line for my internet. I tried putting the Gateway address for HTTP proxy, but it does not work.
Can anyone help me to get around this issue?
