Upgrade Ubuntu from Hardy Heron to Intrepid Ibex – No Release Upgrade Button in Update Manager

I wanted to upgrade my work machine to Intrepid Ibex (Ubuntu 8.10) from Hardy Heron (Ubuntu 8.04), but the update manager was not showing the distribution/release upgrade button. This is due to 8.04/Hardy being an Long Term Support (LTS) release, and 8.10 (Intrepid Ibex) not. Therefore, you’ll first need to enable distribution upgrades in the ‘Software Sources’ settings applet. I followed the instructions here, but the basic idea is thus:

  1. Open ‘Software Sources’ by following these menu choices: System -> Administration -> Software Sources
  2. In the Software Sources applet, select the ‘Updates’ tab
  3. In the section at the bottom entitled ‘Release Upgrade’, select ‘Normal’ from the dropdown menu.
  4. Click the Close button, and let it update your apt package lists

After following these instructions and opening Update Manager, I was still not seeing the release upgrade button. I ensured that my packages were up-to-date, and upgraded anything that needed it, restarted several times, but still no release upgrade button! Ahhh!

Thankfully the solution is simple, you just need to start update-manager with the -d flag in a shell:

user@box$ update-manager -d

This will open up the manager and after a clicking the ‘Check’ button (to update the package list), the upgrade button was showing. Hooray!

    Though Update Manager is supposed to be an easy fix, every time I’ve tried to use it, it has left my system in shambles, especially in the respect of getting the nvidia drivers to work. Users attempting to upgrade to 8.10 be warned: it’s worth a try, but you may end up having to do a clean install anyway. I recommend having a separate /home partition.

    Thank you for this post. Had the same issue, fixed the same way. Strange enough, the problem appeared only on one of two computers being upgraded from 8.04 to 8.10 (I have not got enough motivation to investigate this further). Might worth considering filing a bug report.

    That was intriguing . I like your quality that you put into your writing . Please do move forward with more like this.
