Upgrade Netbook 8.04 to 10.04 no release available

Asked by J.D.

I'm running Ubuntu 8.04 on a Dell Mini9. I want to upgrade to the latest release of Ubuntu 10.04. At one time, our normal system update manager informed me that the new OS was available for upgrade. At the time I chose not to install. Not that I want to install, no matter how many times I run the update manager and select check, it does not see any new releases. I've even gone to the terminal with "sudo do-release-upgrade," and the result says that there are no releases available.

All the Ubuntu site support states that upgrading from 8.04 to 10.04 should be possible with the upgrade manager.
Since it's a netbook, CD or disc installation is not an option. I need to do it through the internet.

Would appreciate any and ALL assistance.

First or all check in System -> Administration -> Software sources at the bottom of the the third tab that Long Term Releases is selected.
Then open a terminal, type

sudo update-manager --dist-upgrade

Type your password and that's it. Make sure you do the upgrade while connected to AC.

I've checked the Software Sources, and the three tabs I have are Updates, Third Party and Authentications. There is nothing on any tab referencing Long Term Releases. Not even the phrase.
I still opened a terminal and ran the line command you recommended and a number of updates were installed, EXCEPT for the OS.

Hi,

You should see at the bottom of the tab "Update" (from Software sources), the last section which says something like "Version update" a drop-down menu with as the last item (out of three) the choice to display Long term releases only.

There is a screenshot where the type of updates is selected.

Also, you might want to check the source of the updates, maybe the mirror you are pointing to is not correctly updated. That is in the same app, but in a different tab.

sudo apt-get install update-manager-core; sudo do-release-upgrade --proposed

Should do it.

I'm currently running Ubuntu 8.04. On a netbook. The screenshots you (Federico) posted were for 10.04 dektop. I don't have any of those options. /home/laura/Documents/Screenshot-1.png

I'll try the suggestion from Actionparsnip next.

I think something else is wrong with my update manager. See the script below freom the terminal session.

What does this command print in the terminal?

lsb_release -a

There's no 8.04 netbook edition, so you must be running 8.04 desktop.

So here (http://www.ubuntu.com/desktop/get-ubuntu/upgrade) it sais how to do it

Upgrade from 8.04 LTS to 10.04 LTS
Network upgrade for Ubuntu desktops (Recommended)

You can easily upgrade over the network with the following procedure.

   1. Press Alt-F2 and type update-manager --devel-release
   2. Click the Check button to check for new updates.
   3. If there are any updates to install, use the Install Updates button to install them, and press Check again after that is complete.
   4. A message will appear informing you of the availability of the new release.
   5. Click Upgrade.
   6. Follow the on-screen instructions.

If all else fails you can do this:

sudo sed -i 's/karmic/lucid/g' /etc/apt/sources.list && sudo aptitude update && sudo aptitude dist-upgrade; sudo aptitude install update-manager-core; sudo do-release-upgrade -d

But only use as a last ditch.

Frederico - Thanks. I've already tried all those basic methods documented on the Ubuntu site. My netbook is a Dell Mini with Ubuntu. regardless of dfesktop or netbook editions, I don't have any of those options under the software sources that you had shown. I don't know how to post a screen shot or I'd show you what I have.

 "Actionparsnip" thanks for the last ditch advice. I'm going to keep this topic open for a time while I continue to research and try other options.

Thanks to all for the advice.

Final Solution. After trying several more update attempts I never did succeed. I did not try the "last ditch" code from Actionparsnip above, becuase I decided if I was willing to do that I can just install from a clean image. So I backed up my data to our network computer, and installed 10.04 Netbook edition via USB image install. Worked great and system is up and running.

Thanks to all those whom tried to help.
