Upgrading Ubuntu from Dapper to Edgy with Update Manager

Upgrading Ubuntu has gotten simpler over time. The graphical utility makes it a breeze to upgrade to the next version. This HowTo should work for any beta version in the future, but keep in mind that installing beta software should only be done by those that are sure they know what they are doing.

If you are ready to take the plunge, run this command from a terminal or run box:

gksu “update-manager -c -d”

The switches tell the regular update manager to check for beta upgrades. This is necessary even when Edgy is out of beta, in order to upgrade from one version to the next.

You will be presented with a screen similar to this one: (you may have to hit the Check button first)


Go ahead and clic k the Upgrade button. You’ll be presented with the release notes window, and click the Upgrade button again.

You will see the progress dialog:

The upgrade process will go out and determine all the packages required, and then prompt you again to click Start Upgrade (makes you wish there was a flag that says ” really upgrade me silently ” )


On my machine, I received this message, and I clicked the remove button, but you can skip the step if you are worried about it.


And that’s all there is to it. You will be prompted to reboot the computer, at which point you will see that you are running Edgy Eft, and you will notice that your Firefox has been upgraded to the beta of Firefox 2.

If you are determined to install from the command line, however, check the other HowTo on installing using apt-get.

    Complete disaster…

    My Compaq M700 laptop wont boot anymore, regardless of what I try… I goes straight to a blank screen and freezes up…

    I would imagine I might have run into a Xorg compatibility/configuration problem, since it’s video card is ATI, but I can’t even get a shell interface.

    I am about to complete to download for the CD image and I’ll try a fresh full reinstall. Hopefully I’ll have my hardware back alive.

    The alternative would be to run back for Dapper (6.06) and stick to it for ever… or at least till 7.04 release.

    So far, 6.10 seemed worse than the original Ubuntu beta I’ve tried.

    I’m sorry to hear about your upgrade troubles. I have heard from a lot of users having problems with the Edgy upgrade.

    If you do figure out what happened, I would love to hear back from you as to the reason.

    I did all these steps but I continue with the same version dapper.

    I downloaded 64 packages, reboot and with this command I get
    cat /etc/issue

    Ubuntu 6.06

    What happened?

    Trying to use this upgrade utility to go from Edgy 6.1 to the Feisty Fawn 7.04. Will let you know what happens. Hopefully my Beryl will still work. ;)

    When I try to do the upgrade, it downloads 35 of the 37 required packages, but fails to get the ones below:

    Failed to fetch Could not connect to (, connection timed out
    Failed to fetch Sub-process bzip2 returned an error code (2)
    Failed to fetch Sub-process bzip2 returned an error code (2)

    When it fails to get these ones, the upgrade is aborted automatically :-(

    Does anyone know what I should do? Any help much appreciated.

    I don’t have the option to upgrade, in the software updates it does not give me the option of upgrading to 6.10. Is there something somehwere that has to be enabled?
