Downgrading Ubuntu

Download Intrepid iso and burn it.After that install it on top of your existing ubuntu partition.Before you do that back up your data/files or make separate home partition if you don't have one.Instruction how to make separate home are on http://www.psychocats.net/ubuntu/separatehome

Sorry for incomplete answer.If your printer works with Uubuntu Intrepid then you have few months left and after that you will use unsupported Ubuntu release.It will be better try to find a way how you can install drivers for your printer in new Ubuntu release.You can open another thread for that if you didn't do it already.

Hi :)

Please try to fix the problem in 9.10 first. Perhaps you just need to install or re-install "cups" when the printer is attached to the machine?

If you do need to downgrade please go to 8.04 LTS as the LTS stands for "Long Term Support". Ubuntu 8.04 should be easily available at the normal download site
http://www.ubuntulinux.org/getubuntu/download
just click on
"Alternative download options, including Ubuntu installer for Windows"
Although 8.04 is LTS that support only lasts just under a year, perhaps less i believe.

There is a sneaky way to fool the installer into making this all a lot easier but it would need your /home to be on its own partition to be really easy. This is an ideal opportunity to move your /home to its own partition of you haven't already done so to make your system very much more robust.

Actually there are 2 main ways to do this.

The traditional way that works with most versions of linux is to do as Zvacet says. Backup all your data to external drives. Then you could go into Synaptic Package Manager and go up to it's "File" menu, choose "Save all markings as ...", make sure to tick the box at the bottom of the save-dialogue-box. Save that little text-file to the external drives too. Then you can do a fresh install of Ubuntu 8.04, and use the "markings" back in the 'new/old' synaptic to reload all the programs you previously had. Then do the update from inside synaptic and finally copy back all the data from your external drive. Most people feel more comfortable with this route as it makes a lot of sense and is what people are most used to doing already with other systems.

For the sneaky way of fooling the Ubuntu installer i would want to see the output of

sudo fdisk -l

where "-l" is a lower-case "-L", just to check how the partitions are currently laid out and how much preparation might be needed before starting.

Good luck and regards from

Thank you all for you help. I now have Ubuntu 8.04 OS on my computer and have downloaded the drivers from Lexmark for my printer but I don't know where to go from there. When I go through the "System-Printing-NEW-..." process I get to where it asks what name printer I'm using. When I click Lexmark it does not have my printer listed. I know there's a way to upload these drivers but I do not know what it is. I was guided through the process with 9.10 but not with 8.04. I believe this is the last thing I need to do to get my printer to work. I hope one of you can guide me through this process. Thanks again

I hope you will find solution there.

Hi :)

Have you been able to test the new Ubuntu 10.04 before it gets officially released?
http://www.ubuntulinux.org/testing/lucid/beta1
Trying it as a LiveCd or as an extra dual/multi-boot would be ideal. Developers and everyone are keen to try to iron out any problems before 10.04 gets officially released so you might find faster & more effective answers to your bug reports which would make 10.04 work better on your system for you

Thanks and regards from
Tom :)
