Karmic / Jaunty question

[TheBigAmbulance]

When Karmic comes out, I am going to be upgrading to the 64bit over the Jaunty 32 bit I have now.

Would it be best practice to do a 'dpkg -l' to list all of the current software I have installed now, and use that as a template when Karmic is installed? I know that there may be a few hickups because of the 32 to 64 thingy. But I'm just trying to get my system right back where it was before the upgrade.

EDIT: I'd end up doing a diff so that the list I have would be filtered through enough to not be redundant.

I don't believe it is possible to upgrade from 32 bit to 64 bit. I think you would need to do a fresh install.

Yup. You can't change architecture with an upgrade.

Re: Karmic / Jaunty question

yup, knew that. I guess what I'm after is once a fresh install is accomplished of Karmic 64bit, I want to load the software that I already had on jaunty. So basically what I'm doing is making a list of what is installed, and then referencing that once I am able to start loading software.

To clone an installation (I'm planning the same, replace 32 bit with 64 bit).

On old system:
sudo dpkg --get-selections | grep '[[:space:]]install$' | awk '{print $1}' > package_list

On new system:
cat package_list | xargs sudo apt-get install

You may encounter a few problems, especially if a given package doesn't support 64 bit, nothing you can't work past.

Thanks Fellas!!

I will definitely try it once Karmic comes out. This is perfect.

EDIT: If I've customized some of the sources (say, added mediubuntu) I would also need to add them as well, correct?

yes, you'll need to re-add all the third party repos you currently use

Re: Karmic / Jaunty question

I installed the 32bit version of Jaunty on this notebook last Feburary and have been WELL PLEASED with the results. My only disappointment was that 3D wasn't as fast as I had hoped it would be. With the PPA patches it's acceptable for GoogleEarth, Stellarium and a few other 3D apps, but TORCS wouldn't run at all, just hang, and the three PenumbraCollection games would not give viewable/readable 3D screens. SecondLife, voice and all, runs like a dream.


I've heard about "problems" running 32 bit apps on the 64bit version, but the claims of 15% speed improvements intrigued me. I pealed 40GB off my Jaunty partition and installed the 64bit Karmic alpha. The improvement in performance is NOTABLE. WITHOUT the PPA patches TORCS runs fast. Stellarium went from 20-30fps to nearly twice that (but the F2 and other secondary configuration screens are unreadable). GoogleEarth is very fast. The fly in the ointment is that SecondLife won't run for very long before it crashes and hangs my PC, even Sysreq REISUB won't recover. I have to power cycle. But, that's probably because Linden Labs hasn't released a 64bit version and their 32bit version doesn't play well with the ia32lib libraries. Over 24% of Linux users are now running a 64bit version of Linux so I expect that will change.

I installed my pro copy of Codeweavers CrossOvere then installed a PLC development tool I've been using for the last 4 years and it runs great.

All in all, running the 64bit version of Karmic is a DEFINITE IMPROVEMENT over the 32 bit version of Jaunty. I plan to stay with it and when it goes gold I will reformat my HD and make it my main partition.

Re: Karmic / Jaunty question

Just a hint to the people going to reformat and reinstall.

This time, make your /home directory a separate partition. This means that you can just keep the data and not need to back stuff up and chuck it back on.

I also put /usr, /usr/local and /var as separate partitions (mainlt for development work and server stuff). It also makes backing up portions a lot easier.

I have karmic on my laptop and netbook, works fine, waiting unit a couple of 3rd party repos I use support karmic before I switch my other machines.

EDIT - 10/06/09 - after todays updates:
My Stellarium speed dropped from 50fps back to 20-25 fps but the F2 config screens are still trashed.
GoogleEarth seems as fast as it was, and so is gl-117, so I don't know what the slowdown in Stellarium means, yet.

I also did the upgrade on my Jaunty partition and the first thing I noticed was that the normally stable Second Life killed the xserver after about 10 minutes of moving around the MCM battle field.

Well, as has often been said, two steps forward, one step backward. It's only a matter of time before those folks at Xorg get all the bugs worked out for a majority of the chips on the majority boxes.

Re: Karmic / Jaunty question

I just had one other though....


Let's pick on Kate. A stock install of Kubuntu installs Kate. But I've uninstalled it, and I don't want it on the cloned install. Will the method above pick up on that?
