I'm trying to upgrade 12.04 to 12.10 using a startup disk, but when I am supposed to choose the type of installation I want, Upgrade option is not available. Can anybody help? I don't want to use Update manager.
I created a USB startup disk from ISO and booted using that to upgrade my 11.10 installation. But when I am not able to select Upgrade from Ubuntu 11.10 to Ubuntu 12.04. The radio button cannot be selected. I am doing a Network upgrade now.
Somehow the install iso disc won't go into upgrade mode. My f10 is on the hard disk, but needing to be rescued. I would do f11 upgrade; but can't get the disk to do an upgrade. It only wants to install.
Currently using 11.10 on a new dell vostro 2420 laptop and wanted to upgrade to 12.04.01lte.
Using the update manager and clicking the upgrade option first came up with a 'failure to authenticate' message and after a restart of the computer I click the upgrade and it will download 2 files then the popup closes and no further prompts/screens come up.
has there ever been any talk of being able to upgrade via live CD/DVD ??? I am just curious if that would may e be a little less buggy than the update manager.
I'm not knocking the update manager cuz I wouldn't have 11.10 without it as for some reason (and I believe its just a lack of drivers for newer hardware) the 11.10 disk won't even boot on my computer.
