[solved] Can't install kde-devel because of unmet dependency

[Chopstick]

Hi there,
I need to compile some software packages from source and need KDE headers for this purpose.
Usually I would just install the kde-devel package, right?
but I can't install it, apt-get gives the following error:

~$ sudo apt-get install kde-devel
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 kde-devel: Depends: kdebase-dev (>= 4:4.1.1) but it is not going to beinstalled
E: Broken packages

Can anyone explain the meaning of this and how I could fix it?
When I try to install the dependency apt-get suggests I get into a cascade of other dependencies. I tired to install them over the following series (all suggested by apt-get):
kdebase-dev > kdepimlibs5-dev > kdepimlibs5-dev > libical-dev
At the last point I get

The following packages have unmet dependencies:
 libical-dev: Depends: libical0 (= 0.43-2) but 0.43-2ubuntu1~intrepid1~ppa1 is to be installed
E: Broken packages

I'm running jaunty now, but I upgraded from intrepid only recently. In Intrepid I was already using KDE4.2 (which was actually much better than my current system, because my ATI driver is not supported anymore... if anyone know an easy way to go back, please tell me...)

I would really like to have this kde-devel thing fixed; a system where I can't install the elementary header files, somehow does not feel right...

Thanks!

Do you have an Intrepid PPA repository at your sources.list ?

Or do you have an Intrepid package of the libical0 installed ?

Re: Can't install kde-devel because of unmet dependency

I used to, when I had Intrepid... and I have the old KDVI from Intrepid.
Now it's all Jaunty in my sources.list.
My libical0 was an intrepid version, yes... but I have no idea what libical0 is...

Anyway, I fixed it now with your link, Rog131, thanks a lot!
I forced the jaunty version of libical0 and then I could install kde-devel without problems! Thanks again!

Do you think I could use the same trick to get the old ATI driver for my graphics-card?
I could force an older version of Xorg and install the old driver...
At the moment the only version of Xorg I can choose is the one currently installed... but I could add the intrepid repos again?
Will installing an older Xorg not damage my system?
(Without an experts opinion I would rather not try it...)

Re: Can't install kde-devel because of unmet dependency

Now I begin to suspect that the way I upgraded to Jaunty was not very "clean":
I simply changed all the intrepids to jaunties (in sources.list) and ran apt-get update/upgrade.
I'm not sure how to do it properly.
The reason for this is that at the time I did that, my system completely crashed with something that I believe is a Kernel-Problem (google...) and I was limited to the consol; the error I got on startup was

iwl3945_enqueue_hcmd failed:-28
iwl3945: No space for Tx

(no guarantee for spelling, I copied it off the screen by hand...)
The upgrade fixed the problem. (And caused another one with my ATI card, but that's a different story...)
Maybe all this somehow messed up my system? It also seem to have a lot of "dead weight" on my kubuntu partition... it's suddenly pretty full... although I have 15Gig on my system partition (I only have 90Gig total, it's a laptop).

Any thoughts on this?
