I have a server still running Ubuntu 8.10. If I run apt-get update I get a bunch of 404 errors on the packages. I've asked a few questions on Server Fault but got nowhere. Here's what I've done:

1. Run apt-get update which returns errors like:

   Err http://gb.archive.ubuntu.com intrepid/main Packages 404 Not Found
   [and same for many other packages]

2. Run do-release-upgrade which returns:

   Checking for a new ubuntu release
   Failed Upgrade tool signature
   Failed Upgrade tool
   Done downloading
   extracting 'jaunty.tar.gz'
   Failed to extract
   Extracting the upgrade failed. There may be a problem with the network or with the server.

3. Edited /etc/update-manager/release-upgrades and changed from Prompt=normal to Prompt=lts (as suggested here). Running do-release-upgrade after this returns:

   Checking for a new ubuntu release
   current dist not found in meta-release file
   No new release found

So basically, it seems like I cannot upgrade because my current distro is out of date and not supported. Is there a way to upgrade direct to 10.x or 11.x?
