I was trying to upgrade my ubuntu 8.04 to ubuntu 9.04 . First I knew I had to upgrade it to ubuntu 8.10 and I did it successfully from the update manager.
Now to upgrade from 8.10 to 9.04 I ordered a free ubuntu cd and now when I want to upgrade from that cd and not by downloading it from the internet. When I insert the CD a prompt is displayed
When I click on RUN it says:This medium contains software intended to be automatically started. Would you like to run it?
The software will run directly from the medium "Ubuntu 9.04 i386". You should never run software that you don't trust.
So I read in the upgrade instructions and then I hit Alt+F2 and type inError autorunning software
Cannot find the autorun program
gksu "sh /cdrom/cdromupgrade"
But nothing happens.
How do I upgrade my ubuntu?
Help me out
