I would like to upgrade my Ubuntu 11.04 from the command line (this is a remote machine I can only SSH into). I am following these directions. I am getting 404's from many commands I am trying to run such as:

  • sudo apt-get install update-manager-core
  • sudo apt-get update
  • sudo apt-get install libkrb5-dev

What can I do to apt-get install these things without 404s from the command line? I can only use the command line.

Here is an example of the 404.

$ sudo apt-get install update-manager-core

Try doing apt-get update first. Without that, it can try downloading files which are no longer current.

Also - as natty is no longer current version - update /etc/apt/sources.list with new repo location, it should be in old-releases.ubuntu.com, instead of archive.ubuntu.com. (and run apt-get update after that).
