How to upgrade from Hoary Hedgehog -> Breezy Badger -> Dapper Drake

Method A (Official)

• First update the update manager:

sudo aptitude update && sudo aptitude upgrade

• Once it has been updated you can upgrade to a newer version of Ubuntu:

gksudo "update-manager -c -d"

NOTE: Try to upgrade from immediately previous versions, e.g. Dapper to Edgy not Breezy to Edgy. If you are running Hoary for instance, upgrade Hoary->Breezy->Dapper->Edgy.

Method B (Alternative)

• First, make sure you're fully upgraded:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

• If you don't have a CD available make SURE you comment/remove the line pertaining to your CD media

gksudo gedit /etc/apt/sources.list

• To upgrade from Dapper to Edgy, just replace (ctrl+h) all instances of 'dapper' with 'edgy' within the /etc/apt/sources.list. (See how to add extra repositories).

• Validate updates and upgrade.

sudo aptitude update 
sudo aptitude dist-upgrade

(Note the use of aptitude rather than apt-get. Please use aptitude as it handles dependencies better and is more likely to succeed in upgrading your system.)

• Save your session, reboot, and enjoy.

NOTE: Try to upgrade from immediately previous versions, e.g. Dapper to Edgy not Breezy to Edgy. If you are running Hoary for instance, upgrade Hoary->Breezy->Dapper->Edgy.
