Hey guys,

I'm a huge fan of the ubuntu 8.10, but there are some things in it that do not work quite right like they did in Hardy Heron (cairo-dock, audacity, etc.) is there a safe way to downgrade from Ibex to Heron without screwing anything up?

Thanks in advance

Safest way is to back up your data and then do a clean install of Hardy

Steve1961 is right.

It's pretty much a one way street.

If it's pretty much a one way street, then I'll just wait until developers fix the problems in cairo and in audacity (way too technical for me to help). Also, AWN was too glitchy for me. Are there any like AWN and Cairo that work well in Ibex?

There actually is a method for downgrading debian based distros-it's been an often discussed topic. There is a Ubuntu wiki entry on that here (https://help.ubuntu.com/community/DowngradeHowto)-be sure to read the intro.

For anyone else who is feeling experimental or wanting a little OS adventure a debian based write up on pinning to accomplish downgrading is here (http://ryandaigle.com/articles/2005/10/31/listing-downgrading-unstable-testing-debian-packages).

Thanks all, I'll try Kiba and just forget about downgrading. I don't want to screw anything up :)

LOL, that is not for the feint of heart and is more complicated the re-installing.


I have *YET TO TEST THE PROCEDURE*. Please pursue at your own risk until this documentation is completed!And


we'll use the example of downgrading Ubuntu Breezy to Ubuntu Hoary

Also notice the last line of that wiki page :


The last step probably will end up a catastrophic mess of incompletely installed packages. We need to fix that now.bolded emphasis added by me :)

I think that last sentence sums up the reason this is not advised very often.

Breezy = 5.10 (3 years old and the wiki page is not yet "completed")

Hoary = 5.04.

So take that advice with a large grain of salt.

With all of that said, if you know how to actually do this please consider updating the wiki :twisted:

If you decide to go back to 8.04, then after you have backed up your data; during the install process, take time to manually partition the drive.
Ext3 10~20gb for /
Swap 2gb
Ext3 rest of drive for /home

This way /home is on its own partition, then if you ever regret an upgrade a clean install is as simple as not formatting that partition during the install process. Any clean install of course means reinstalling software, but thats all neatly available through synaptic.

GL have fun, and always backup before you move forward.

I have done this with debian. I added a link to my orginal post that shows most of what's required.
My reason for adding to this thread was to point out that it's possible to make the attempt if one wants to-whether or not it's practical I leave to those who want to try it.
One doesn't learn by staying in the parameters of tradition or what's accepted practice.

The notation here says

It appears someone has reviewed the wiki then.

I agree with phildia, all you need is a strict pin to downgrade.

[EDIT]
OK, I ran this in a VM... and I have reviewed the steps I previously posted and have made judgmental decisions on what to do when things seem to go pear shaped...

First, change your sources back to Hardy. Usually sed is the move efficient way of doing this.

sudo sed -i 's/intrepid/hardy/g' /etc/apt/sources.list

And create your preferences files.

sudo touch /etc/apt/preferences
sudo ln -s /etc/apt/preferences /var/lib/synaptic/preferences


And we can start the magic :D

sudo gedit /etc/apt/preferences
and input the following:


Package: *
Pin: release a=hardy
Pin-Priority: 1011

Package: *
Pin: release a=hardy-security
Pin-Priority: 1101

Package: *
Pin: release a=hardy-updates
Pin-Priority: 1001

Save and quit.

Then run:

sudo apt-get update
sudo apt-get upgrade
[EDIT]
OK, I have gotten through this procedure, and I have documented what happens and fixes.
1) language-pack-en-base fails upon configuring... this is OK, run

sudo apt-get install -f
To fix this and run upgrade again.

sudo apt-get upgrade
And wait for about 20-30 minutes for it to complete.

Once everything is finished, reopen the preferences file, and remove what you everything you put in.

sudo gedit /etc/apt/preferences

Now reboot and pray :)

BE SURE TO BACK EVERYTHING UP FIRST BEFORE ATTEMPTING THIS SENSITIVE PROCEDURE

If it works, you will probably find yourself with a few extra unneeded packages from intrepid still, such as the 2.6.27 kernel. You can choose to purge these packages if you prefer the 2.6.24 instead.

Thank you tinivole.

I tried this on a test system, using Virtualbox 32 bit guest.

The pinning and down grade went fine, but the downgrade was not complete, and the resulting system was not "normal". By that I mean if you open synaptic and update ("Mark all upgrades" -> apply) the system will remove critical parts of the system.

So I would caution that while initially pinning and downgrading "works", the downgrade is not perfect and the resulting system is a bit touchy, to say the least.

yes, i was aware of this method but tried it myself several years ago on a Debian system. It took so long to repair the resulting mess that unless you really know what you're doing it takes much longer than a simple backup and reinstall.

If I use WUBI to dual-boot with XP, and I've installed Ibex, would there be a difference if I reinstalled Heron? How would I reinstall Heron?

I would remove ibex and install over the top.

In the end, I just searched which WUBI to use for 64-bit 8.04.1 Ubuntu and downloaded it and installed it. Of course, unlike 8.10, internet worked right away, graphics worked right away (my 2 main problems). I'll wait for others to experiment with later releases, like 9.04 (Jackalope?) rather than download install and freak on the first day, prior to learning that a distro is so buggy!
