Another post regarding how to upgrade from Dapper to Hardy

Here is how I did it:

Ubuntu 6.06 to Ubuntu 8.04 Upgrade (Server)

I verified that my current install was completely up to date:

sudo aptitude update
sudo aptitude upgrade
sudo aptitude dist-upgrade

Also, to be thorough, this is what my sources.list looked like (each ‘deb’ entry should be one single line):

deb http://archive.ubuntu.com/ubuntu dapper main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu dapper-updates main restricted universemultiverse
deb http://archive.ubuntu.com/ubuntu dapper-security main restricted universemultiverse
deb http://archive.ubuntu.com/ubuntu dapper-proposed main restricted universemultiverse
deb http://archive.ubuntu.com/ubuntu dapper-backports main restricted universemultiverse

Once I had applied all updates (if you’re already up to date, you don’t need a reboot) I then installed the server-based update utility:

sudo aptitude install update-manager-core

Once this is installed you’re ready to begin the upgrade process.  You can start the upgrade using:

sudo do-release-upgrade


Or use CD-ROM
$ mount -t iso9660 -o loop ~bvi/ubuntu-8.04-server-i386.iso /cdrom
$ apt-cdrom add

This should show output similar to the following as the CDROM is added to the Repo list.

Using CD-ROM mount point /cdrom/
Unmounting CD-ROM
Waiting for disc…
Please insert a Disc in the drive and press enter
Mounting CD-ROM…

Scanning disc for index files..
Found 2 package indexes, 0 source indexes and 1 signatures
Found label ‘Ubuntu-Server 8.04 _Hardy Heron_ – Release i386 (20080423.2)’

And should add a to the top of your /etc/apt/sources.list similar to the following:

deb cdrom:[Ubuntu-Server 8.04 _Hardy Heron_ – Release i386 (20080423.2)]/ hardy main restricted

Finally the update can be performed

do-release-update
