I might be wrong (won't be the first time, or the last), but I think that until 12.04 goes 'final', there isn't an upgrade path - you have to do a new installation. I've almost never done a distribution release upgrade, opting instead to do clean installations (I have three separate Kubuntu's on my HP, and I rotate new releases, installing the latest over the 'second' oldest).

Added:

Yup. I'm wrong. What you described as trying follows right along with the Kubuntu 11.10 to 12.04 LTS Upgrade instructions.

If you set Software Sources > Updates > Release upgrade > Show new distribution releases to Long term support releases only and log out/reboot, then the notifier should pop automatically letting you know that a New Release is available. If that does occur, don't use it to do the distribution upgrade. Close that notifier and then try the Alt+F2 kubuntu-devel-release-upgrade route again. If that still doesn't work, open a console:

Code:

kdesudo do-release-upgrade -m desktop -f kde -d

I note that in your post, the command above was missing the desktop option.

Following:

but stopping the upgrade to the confirmation window.

Hmm -- looking how this shold work...

The kubuntu-devel-release-upgrade

kubuntu-devel-release-upgrade: /usr/bin/kubuntu-devel-release-upgrade

Code:

cat /usr/bin/kubuntu-devel-release-upgrade

#!/bin/sh
kdesudo "do-release-upgrade -m desktop -f kde -d"

the do-release-upgrade is by man page:

So, if executed from the terminal, one must use kdesudo instead of (what i posted, and have 'corrected') sudo. I guess I should have known that, as it executes a graphical distribution upgrade process.

**GreyGeek** · Mar 04, 2012, 04:06 PM

While it may not be true for Kubuntu, my experience with upgrading to a new release versus a fresh install has been that a fresh install is always better. So, I'd back up all my important data. More work, for sure, but the results are cleaner and better, IMO.

Maybe ?

Background

Earlier: http://www.kubuntuforums.net/showthr...tions-in-12-04

The anacron is updating the package database. The update-notifier-common (it seems to be a bunch of script files) is writing:

/var/lib/update-notifier/dpkg-run-stamp
/var/lib/update-notifier/updates-available
/var/lib/apt/periodic/update-success-stamp
/var/lib/update-notifier/release-upgrade-available

It seems that the do-release-upgrade (a python script) is using the /var/lib/update-notifier/release-upgrade-available.

Testing

Removing the /var/lib/update-notifier/release-upgrade-available and rebooting.
After the reboot:

:~$ kubuntu-devel-release-upgrade
Checking for a new ubuntu release
No new release found

Touching myself:

Code:

sudo touch /var/lib/update-notifier/release-upgrade-available

There should be release-upgrade-available...

Code:

ls -l /var/lib/update-notifier/release-upgrade-available

-rw-r--r-- 1 root root 0 2012-03-05 09:19 /var/lib/update-notifier/release-upgrade-available

and the kubuntu-devel-release-upgrade is working...

Something to Try

1) Make the /var/lib/update-notifier/release-upgrade-available

Code:

sudo touch /var/lib/update-notifier/release-upgrade-available

2) Launch the kubuntu-devel-release-upgrade

**gdonwallace** · Mar 05, 2012, 06:41 PM

Thanks for all the suggestions guys (gals??), but I still am getting the same results. Will keep working on the issue. As a note, release-upgrade-available was already at zero byte file. But I went ahead and deleted it and did the touch command to create a new blank file.

**gdonwallace** · Mar 07, 2012, 07:19 PM

At this point, after much searching on a few other forums and through google I still have not found an answer that works. I guess I will need to wait until 12.04 goes live and see if I will stick with (K)ubuntu or move on to another distro.

**The Liquidator** · Mar 19, 2012, 05:20 PM

I have the same issue - the upgrade instructions don't work at all for me.

Using the command line I get the following:

ian@ian-MXC051:~$ kdesudo "do-release-upgrade -m desktop -f kde -d"
Checking for a new ubuntu release
No new release found
ian@ian-MXC051:~$

**bsniadajewski** · Mar 19, 2012, 08:35 PM

Try replacing all instances of "oneiric" with "precise" in sources.lst (maybe delete the "#deb cdrom ... " line while you're at it) and go through the "sudo apt-get update && sudo apt-get dist-upgrade" or use Muon, clicking on "Check for updates" then "Ful upgrade".

**The Liquidator** · Mar 20, 2012, 04:49 AM

Thanks

I have shied away from that for now as I have a number of ppas that probably don't have precise versions yet so to avoid conflicts I've left well alone for now.

One thing does concern me though - I have got the live cd of 12.04 beta 1. When I run it, either as a CD or a USB, network-manager recognises all wireless connections in range but sees all those with WPA as WEP! wpasupplicant is installed so I can't see what might be causing this. Has this happened to anyone else and, if so, will it correct itself on install?

Thanks

Ian

**GreyGeek** · Mar 20, 2012, 09:55 AM

My Precise installation's KNetworkManager, which I always replaced with wicd in previous releases because it was unreliable, has been working great in Precise. It shows at least twice as many APs as wicd did. Either that or twice as many people in my area are running wifi now.

Anyway, the icons indicating AP type are showing them correctly. A green shield is a WPA, a yellow shield is a WEP and a red shield is insecure.

**The Liquidator** · Mar 20, 2012, 10:55 AM

Thanks GG
I agree that the network manager has become much more reliable - I haven't used Wicd for about a year now.

Here's what I find so strange - I have downloaded two 12.04 ISOs and the results running the resulting live CDs/USBs are the same - connections that I know to be WPA2 show the yellow shield and, worse, do not have a WPA setting available so I cannot wirelessly connect to the internet at all. Very odd that it's not happening to anyone else but I currently see it as something of a roadblock.

**bsniadajewski** · Mar 20, 2012, 07:22 PM

No problem. At least kee pit in mind once all of the PPA's you have enabled have precise versions and you still have those version upgrade problems

**gdonwallace** · Mar 21, 2012, 03:06 PM

Well I have managed to do the upgrade to 12.04.

I took the advice, and changed my sources.list. I replaced all occurrences of Oneric with Precise and was able to do the dist upgrade that way. So far it seems to have worked, I have not had much time to play around with it yet. But should over the next few days.
