Today, i am sharing the iso image based upgrading, using my hard disk to upgrade. The steps for the upgrade are as follows:-
- Download the Ubuntu alternate CD i downloaded the ubuntu-7.10-alternate-i386.iso image
- Keep the iso on your unused partition
- Back up all necessary data.
- Mount the iso image.
- Run the cdromupgrade script from the mounted iso
- Go through the upgrade and enjoy the new Ubuntu 7.10.
When i say unused partition, i mean any disk partition which would not change during the upgrade process. In my case, i used my windows partition which i mounted read only (ntfs) in Ubuntu 7.06.
I kept the iso image on my windows partitions and mounted the iso image from the same.
>mount -o loop ubuntu-7.10-alternate-i386.iso /ubuntugutsy
When running the cdrom upgrade, the system would ask for permissions to download latest updates from the Internet. i would recommended you to download the same.
In case of using latest updates, the upgrade process to handle to additions problems. Firstly, it would handle packages which may not be included in the cdrom but are upgraded in 7.10 repository . At the same time, it would also install latest version (if any) of software available on cdrom also. This would make your life easier later on.
