Upgrade Ubuntu Gutsy to Hardy (Alpha 4)
First off, the easiest way to go about checking out Hardy is by downloading a live cd image and doing a fresh install on a separate partition. This avoids spoiling your Gutsy installation. You can do that by going here:
But if living on the edge is more your style, you can upgrade your current Gutsy release to Hardy Alpha 4 by doing the following things. Before you do so, you should know that Hardy Alpha 4 is by no means stable, and should only be done on a system that you want to play around with. That being said, here’s how it’s done!
EDITING THE REPOSITORIES
Open up your terminal of choice. First off, backup your current repository list. Type:
Now, open up the original sources.list file:
In Gedit, click Search >> Replace.

Fill in the fields as above, replacing the word Gutsy with Hardy. Click Replace All, and save the file.
UPDATING REPOSITORIES WITH APT-GET
Now type:
This will update the repositories. You may notice the Ubuntu update manager icon telling you there are several hundred updates available. Ignore it, as we’re going to update things using the terminal instead.
FINALLY: UPGRADE TO HARDY
Here’s the big step. If you’re having second thoughts, you can still back out now! Otherwise, type:
Everything is downloaded and installed. This could take a while. Go watch something on TV.
When it’s finished, you’ll need to reboot the system. Type:
And you’re finished! Hopefully it all went smoothly. It is an alpha release, but I personally haven’t experienced any major problems.
Alternative Method
There is another method which is a little easier, but also less customisable, and will only work so long as Hardy is listed as “developmental” (which means upon Hardy’s release, this method of upgrading will not work). Nevertheless, here’s how it’s done. Simply type in a terminal:
sudo update-manager -d
Release 8.04 (Hardy) will be detected and can be upgraded to by clicking the “Upgrade” button.

Correction: sudo shutdown -r now
“sudo reboot” should work equally

Thanks for the post! I’m finally making the switch, and this helped out a lot

Just wondering, will I loose everything on my hard drive if I upgrade?
Sorry if it’s a stupid question, but I’m new to Linux.

Hey James, no, you won’t. One of the “new” features of Hardy is to even preserve the contents of your “Home” directory during the upgrade, as long as you don’t do a clean install, you should retain all your personal files.

if you dont know that then you really shouldnt be trying an alpha release.stick with 7.10.

start a terminal, and run “sudo update-manager -d” will work a lot easier

May be In search & replace wont be best option if people are using local country repositories? Do all local country repositories will mirror also pre-release stuff?

I test it, but there is some problems, and can’t explain what ?
nautilus can not be opened any more segmentation fault error
other application can not be executed from ordinary user, we must execute it wit prompt command using root privilege !!!!
but it’s coooooooool

I’ve just upgraded, I too had a problem with nautilus once I rebooted but it’s better now. The odd thing is it removed xmms and Avant window navigator and I don’t know why. Other than that, it’s fine so far. The International clock is very nice

Ohm and here’s how I did it. I did Alt+F2, ran the command ‘update-manager –devel-release’ and it told me there is a new release, so I clicked on upgrade.

I faced a severe problem.. During my update the power went off and so its done a partial update and everything seems to be messed up!
May 17, 2008 at 5:50 pm
I’m trying this way now because last time i did the upgrade, it failed
Let’s see what happens now!

Somehow i missed the point. Probably lost in translation
Anyway … nice blog to visit.
cheers, Outwear!!!!

If you want to read a reader’s feedback
, I rate this post for four from five. Detailed info, but I have to go to that damn msn to find the missed bits. Thanks, anyway!

Presumably you’re upgrading from Intrepid to Jaunty now (since this post was written just over a year ago). I’m fairly sure it should all work still, but keep in mind that when editing sources.list change the word “intrepid” to “jaunty” instead of what’s written in the post.
