My upgrade from Ubuntu Intrepid (actually Kubuntu) to Jaunty Jakelope, 9.04, including screenshots and solutions to errors encountered.

Upgrading from Ubuntu Intrepid (8.10) to Jaunty (9.04)

Errors and all!

One can upgrade to Jaunty Jakelope, Ubuntu 9.04 (ie the April 2009 version), from Intrepid Ibex (8.10) simply by using Alt-F2 to open a run dialog and typing:

update-manager -d

In theory.

Practise is always more complicated. Though this upgrade was pretty smooth compared to some I’ve made in the past.

Problems from the off

W:Failed to fetch http://archive.canonical.com/ubuntu/dists/jaunty/Release Unable to find expected entry  main/binary-i386/Packages in Meta-index file (malformed Release file?)
, E:Some index files failed to download, they have been ignored, or old ones used instead.

Well, that didn’t look too hot. The file that it “failed to fetch” was accessible, as confirmed in my browser so there must be some other issue. Well a bit of judicious googling confirmed that removing the “partners” repositories from the list in sources.list allows the install to proceed. The best way is probably to use this in the Alt-F2 run dialog (krunner for me as I’m using Kubuntu with KDE4):

gksudo gedit /etc/apt/sources.list

or for kde

kdesu kwrite /etc/apt/sources.list

or just use your favourite text editor. Personally I do this in nano using “sudo nano …” from a command line prompt, but any editor works just as long as you’re running with root permissions.

Find the line that says “partner” and comment it out, it will look something like this when commented out:

## Uncomment the following two lines to add software from Canonical’s
## ‘partner’ repository. This software is not part of Ubuntu, but is
## offered by Canonical and the respective vendors as a service to Ubuntu
## users.

#deb http://archive.canonical.com/ubuntu jaunty main partner universe restricted multiverse
#deb-src http://archive.canonical.com/ubuntu jaunty main partner universe restricted multiverse

Try update-manager -d again

In case the title didn’t give you the hint, try update-manager -d again from the Alt-F2 prompt.

Now, everything should work fine. In a couple of hours (that’s how long it took for me on 4Mb broadband on a 1.1GHz Athlon) you’ll have  a fresh new Jaunty Ubuntu staring back at you.

Surprise

Not quite how things worked for me.

But it was easy enough to delete the apt file cache (“sudo apt-get clean”) and clear up my trash:// and some unneeded downloads I had lying around. Then, you guessed it, “update-manager -d” again and now we’re cooking!

Once all the files are downloaded then the install begins. Twenty minutes of downloads led to 1hr 30mins of installing for me.

My install ended with another error. This appears to have been a problem with installing the “MS Core Fonts”. However, they installed by themselves next time I ran my usually apt manager (“synaptic” equivalent to KDE’s “adept” ).

The error doesn’t appear to have made a difference. I was suprised that I wasn’t rebooted at the end of the install … too much time using MS Windows I guess … I rebooted anyway just to be sure everything was OK, then I checked that the new kernel was being run and finally did “update-manager -d” one last time to be sure that the current version of Ubuntu reported was Jakelope.

Even more upgrade errors for Jaunty

I also had an error:

Xlib: extension “Generic Event Extension” missing on display 0:0

this hasn’t prevented the install and doesn’t appear to be a problem now that I’m using Jaunty. YMMV, and probably will.

How was it for you?

For me the upgrade hasn’t made a whole heap of difference. No visible differences as yet as I tend to follow the bleeding edge on this computer. How about you?

If you need help with other errors then I heartily recommend using Ubuntu Forums.

Useful post? Go on, buy me a treat I promise I'll share!
