how do I revert to gutsy?

[ronacc]

how do I revert my gusty install back to gutsy after changing my sources.lst to hardy and running update manager ? I did a fresh install of gutsy on another drive specificly for updateing to hardy and it would not boot past "waiting for root file system" then after I had updated my original install I got the fresh one working so I would now like to revert my original.

Sorry I can't help you with your problem, But you should just rebuild it with the Gutsy install media. With your question the way it is posted it leaves one to assume that this is a catastrophic problem & as we are playing with development software heed should be taken not to use production machines for development work.

thankfully it is not catastrophic , I have a box just for testing . I was going to keep the gutsy install for awhile since it was originaly upgraded from fiesty , and much tweaked . I wanted to give Hardy a fresh install of gutsy release so that it would be a fair test . If I can't find out how to revert that install I'll just upgrade them in parallel and see if there are any differences I might find some useful info that way, afterall it is a testing box. I already learned something useful , the reason the fresh install wouldn't boot was that I also have FC8t on that box and am using Fedoras grub to boot with , when I added the boot stanza , I got the UUId from hardinfo , well hardinfo lists the uuid in 2 places , in one of them it shows dashes in the uuid as underscores and that was the one I cut and pasted for the bootline , once I had caught on to that ( it took a couple of days) the fresh install booted fine.

I can't think of a good/automated way, but you should be able to do it manually. I think the following would work but haven't tested and it wouldn't be too fun. Luckily there haven't been too many upgrades yet.

1) Switch your sources list back to gutsy and update.
2) Check in Synaptic under File -> History to see which packages have been upgraded since you went to Hardy.
3) Now find each package that was upgraded and individually force the version (ctrl+E) to the gutsy one.

If anyone sees an obvious problem with the above please post so no one gets messed over by my possibly bad logic.

Thanks jasay , I have already switched back to the gutsy repos in that install and have printed out a list of the packages that were changed from the apt log file . I will try your method later this evening and report back if it works or not .

seems to have worked mostly , a couple of the hardy files refused to downgrade and a couple of others whanted to remove a bunch of stuff that HADN'T been upgraded I'd say I'm 80 to 90% back where I started. its late now I'll try a couple of other things on the holdouts tomorrow . system monitor says I'm back in gutsy and the thing didn't croak on reboot :)
