How to install software or upgrade from old unsupported release?
I am unable to install anything higher than ubuntu 9.04 on a computer, I cannot explain why, I have tried the live CD's for all the versions down from 12.04 and the only one that will boot up is version 9.04. Consequently, I would like to move up from this download to version 12.04 but I cannot because the repositories are no longer supported. And yes I have tried booting with live CD's, I have tried with usb, I have tried changing the bios, I have tried all the options that they say in the troubleshooting menu, please... There is something different between the versions though, the 12.04 version I just get a black screen with a cursor, while the other versions I get some text talking about something called PXE-2.1 adaptor, something PXE2.1 exiting and then windows starting up once more (and yes I have checked to see if the CD/USB was made correctly).
So back to my original question; how do I move from version 9.04 to version 12.04 using update manager right now...thanks
This seems weird
sudo apt-get install update-manager-core
[sudo] password for lin:
Reading package lists... Done
Building dependency tree
Reading state information... Done update-manager-core is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
How can it be the newest version, there must be something wrong
So now I have started to add the repositories for different versions of Ubuntu and it is upgrading to 9.10, which is a good start, so I think I just have to keep adding the repositories and trying to upgrade...is there any other help that anybody can give me????
