This is how I just upgraded from Ubuntu Gutsy Gibbon 7.10 to Hardy Heron 8.04…
This is great if you are doing more than 1 Ubuntu install, to save bandwidth.
The other alternative would be to do a clean install, but this I did not want this time….
It was a breeze with everything working 100%.
Upgrading using the alternate CD/DVD
Use this method if the system being upgraded is not connected to the Internet.
1.
Download and burn the alternate installation CD.
2.
Insert it into your CD-ROM drive.
3.
A dialog will be displayed offering you the opportunity to upgrade using that CD.
4.
Follow the on-screen instructions.
If the upgrade dialogue is not displayed for any reason, you may also run the following command using Alt+F2:
gksu “sh /cdrom/cdromupgrade”
Or in Kubuntu run the following command using Alt+F2:
kdesu “sh /cdrom/cdromupgrade”
