Continuing the series on upgrading Ubuntu to 8.10 “Intrepid” today I’ll outline using a downloaded CD for the upgrade. If you already have the CD downloaded there is no need to use one of the previous methods and use your bandwidth. You already have the packages available on the CD, and you can use that as a source.
What you’ll need to do is insert your 8.10 “Intrepid” CD into the machine to be upgraded. You should recieve a graphical notification that a new version is available and the upgrade process should begin.
If for whatever reason this process does not start automagically you can manually begin the process with the following:
gksu "sh /cdrom/cdromupgrade"
If you are a Kubuntu user you can begin the process with this command:
kdesu "sh /cdrom/cdromupgrade"
Should I compulsorily update my 8.04, before installing 8.10 from alternate CD?
@v155r – yes, apply any remaining updates to your current installation before upgrading to the next release.
