Ubuntu – Downgrading from ubuntu 11.10 to 10.10, keeping installed programs

10.1011.10downgrade

I recently upgraded from 10.10 to 11.04 then 11.10, and I'd like to revert back to 10.10. I understand that you cannot downgrade a version as easily as you can upgrade, and that I'll probably have to get the boot CD again and reinstall the whole thing.

I know that I can keep most of my files by saving the /home directory, so 2 questions:
Once I've gone back to 10.10, can I juts copy my old version of home over the freshly installed one?

Is there a way to keep all of my installed programs, or some sort of way of getting the new install to automatically install them? Will I have to go through the tricky setups of things like TeX all over again?

Thanks

I share your difficulty and i'm thinking of this too.

Downgrade is not officially supported but this guy on youtube shows a successful downgrade.

Rebooting

Picking from the grub > Previous Linux versions > Kernel 2.6.38-10

...and the (K)Ubuntu is telling that i'm running with the 2.6.38-10-generic /2/.

enter image description here

...won't it cause any problems?

Well ;) you could tell us...

How to Completely Remove Macbuntu – Formatting Included

If it is a GTK+ theme, then it would have left some files in ~/.themes, possibly also in ~/.icons and others.

To be certain, you can manually open the uninstall script, look for all folders that are marked for removal, and manually clean these up your self.
