upgrade ubuntu dapper to ubuntu edgy

Upgrading Ubuntu Dapper from ubuntu Edgy will takes a little time.I have tested it and It is working good for me.

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

Run this command on the terminal:

gksu "update-manager -c -d"

A window Will Open like below:



Now Press Upgrade




You will see the progress dialog:



The upgrade process will 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.



That’s all.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 2.0

Here’s a another quick way to do it :

Goto terminal ( From Desktop, goto Applications->Accessories->Terminal )

user@desktop:~$ sudo sed -e 's/dapper/ edgy/g' -i /etc/apt/sources.list

user@desktop:~$ sudo apt-get update

user@desktop:~$ sudo apt-get dist-upgrade

Then lay back while your distro upgrades itself.
