Today I have upgraded my Ubuntu Dapper Machine to Ubuntu Edgy this is still is beta version.
We can Use Two methods to upgrade Ubuntu Dapper to Edgy
1) Using GUI
2) Using apt-get
Upgrading Ubuntu Dapper to Ubuntu Edgy
Method 1
Using GUI
If you want to upgrade using GUI use the following command
gksu “update-manager -c -d”
The “-d” switch instructs Update Manager to consider pre-release versions and “-c” switch tells it to look for upgrades at all.You should see the following screen here Now you can see 6.10 is available for upgrade click on upgrade
Now you can see the following screen with the no.of packages available for download here click on start upgrade
Here it starts preparing the upgrade
You can see in this screen downloading required packages is in progress
Installing all the required packages in progress
After installing these packes you should see the following screen and here you need to click on restart and it will reboot your machine to take your new ubuntu 6.10 installation to effect all changes.
You can check the ubuntu version installed using the following command
sudo lsb_release -a
Output Looks like below
Distributor ID: Ubuntu
Description: Ubuntu edgy (development branch)
Release: 6.10
Codename: edgy
Method 2
Using apt-get
Edit your /etc/apt/sources.list as root. Change every occurrence of dapper to edgy.
Use any prefered editor. If you have a CD-ROM line in your file, then remove it.
sudo vi /etc/apt/sources.list
or
use the following Simple command
sudo sed -e ’s/\sdapper/ edgy/g’ -i /etc/apt/sources.list
Now you need to update the source list using the following command
sudo apt-get update
Upgrade using the following command
sudo apt-get dist-upgrade
Double check your process was finished properly using the following commd
sudo apt-get -f install
sudo dpkg –configure -a
Now you need to Reboot your machine to take your new ubuntu 6.10 installation to effect all changes.
I have some applications installed in my ubuntu dapper machine after upgrading to edgy some of my applications also upgraded to latest versions

Thanks for the explanation, I made the apt install…, Only one thing at the end of the tutorial you put: sudo dpkg –configure -a, And I think it is: sudo dpkg –-configure -a.

This guide worked for me except for one thing: I had to manually remove xserver-xorg-core and then install it again with the following command.For some reason this was held back during the command ’sudo apt-get dist-upgrade’ earlier.
Try running sudo apt-get dist-upgrade again after its run to ensure that you have actually updated all your files. Check if there were files that were helf back and see if “xserver-xorg-core” was one of them. That being the case do the following
1.To remove : sudo apt-get remove xserver-xorg-core
2.To re-install: sudo apt-get install xserver-xorg-core
This cause my xserver to bomb saying it could not find GLCore and “fixed” font.

Hello !
I have this error in upgrade :
An unresolvable problem occurred while calculating the upgrade.
Please report this bug against the ‘update-manager’ package and include the files in /var/log/dist-upgrade/ in the bugreport
An idea ?

I also want to upgrade. from 6.06 to 6.10 .
First I verify my current ubuntu version:
tm@penguin:~$ sudo lsb_release -a
Password:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 6.06.2 LTS
Release: 6.06
Codename: dapper
tm@penguin:~$
Then I use the command
gksu ‘update-manager -c -d’
with single quotes (otherwise gksu complains about the -c option):
tm@penguin:~$ gksu ‘update-manager -c -d’
/usr/lib/python2.4/site-packages/apt/__init__.py:17: FutureWarning: apt API not stable yet
warnings.warn(”apt API not stable yet”, FutureWarning)
the update-manager starts and gives me the information that my
system is up to date. There is NO text which says:
New distribution release ‘6.10′ is available.
So I have no possibility to upgrade.
Can somebody help me.
