Ubuntu Dapper to Edgy Upgrade - Using Update Manager
Simplifying Ubuntu Upgrades
The process of upgrading Ubuntu has become increasingly straightforward with time. Utilizing the built-in graphical interface, transitioning to the newest version is now remarkably easy.
This guide details the steps involved, and should be applicable to future beta releases. However, it’s crucial to remember that installing beta software is best reserved for users comfortable with potential instability.
If you’re prepared to proceed, execute the following command within a terminal or run box:
gksu "update-manager -c -d"
Initiating the Upgrade Check
These parameters instruct the standard update manager to specifically search for beta upgrades. This functionality remains necessary even after a version has exited its beta phase, facilitating upgrades between major releases.
You will then encounter a screen similar to the one shown below. You may initially need to press the "Check" button to initiate the search.
Proceed by clicking the "Upgrade" button. The release notes window will then appear; click "Upgrade" again to confirm.
The Upgrade Process
The system will then display the progress of the upgrade.
The upgrade process will identify all necessary packages. You will then be prompted to initiate the upgrade. A command-line flag for silent upgrades would be a welcome addition!
Final Steps and Completion
During the process, you might receive a message regarding obsolete packages. I chose to remove them, but you can bypass this step if preferred.
Once completed, a reboot is required. After restarting, you will be running the new version, in this case, Edgy Eft, and your Firefox browser will be updated to the beta version of Firefox 2.
For those who prefer a command-line approach, refer to the alternative guide detailing installation using apt-get.
