Cannot upgrade to new Ubuntu version behind proxy server

Asked by Nickolas Holloway

I'm currently running Ubuntu 10.04 (Lucid Lynx), and I would like to upgrade from Lucid Lynx to Natty Narwhal. I'm currently running behind a proxy server, and it will download all but three repositories, which is strange, considering apt-get install and apt-get update works. I don't need to configure the proxy server to get on the Internet. Just because of how this server functions, as long as I enter my user name and password into the login page in my browser, I can browse the net. Thinking that may have been the problem, I configured the proxy settings, applied it to all proxy forms, and set it as system-wide, to no avail. I followed the instructions given in Question #156495 (https://answers.launchpad.net/ubuntu/+source/update-manager/+question/156495) but was unsuccessful. My terminal output follows below, when I enter the commands in Question #156495.

tell apt about your proxy, either be exporting the http_proxy variable

export http_proxy=http://your.proxy.com:12345

or by modifying your apt.conf file

My proxy server is in this format - 11.1.11.1:8080. Do I enter that the same way?

Enter it like http://11.1.11.1:8080, yes. So, if you use the first method, it will look like:

export http_proxy=http://11.1.11.1:8080

Or you can download the alternate ISO, mount it then use the upgrader there in an offline style.

However, you would have to download two alternate .iso images -- one for Maverick, and one for Natty.

Since Ubuntu 11.04 Natty Narwhal is not a Long-Term Support release, you cannot upgrade directly to it from Ubuntu 10.04 LTS Lucid Lynx. You must first upgrade to Ubuntu 10.10 Maverick Meerkat, and then upgrade from Maverick to Natty.

(This applies equally when upgrading in the Update Manager or via the do-release-upgrade utility, but it's only when upgrading using alternate CD's that you're likely to make a mistake as a consequence of not taking heed of it.)

Can you help with this problem?
