@Simon: It's not clear to me what's going on with your system that you think is related to this bug. Neither libmagick++5 nor VLC are Python packages. You will need to be clearer about the possible relationship. Also, I see you have a mix of quantal and precise sources. That is generally not a good idea (although I did not look at what's in that PPA to see if there is an actual problem).

sorry ... i posted that comment not because i have problem with vlc or libmagic but because i have problem with these:

The following partially installed packages will be configured:
  python3-aptdaemon.pkcompat python3-software-properties
  software-properties-common software-properties-gtk
  software-properties-kde

it doesnt want to properly configure them... with them also python3 itself and the python3 debugging symbols...

amm... it also seems the full text which i copy/pasted here is missing (truncated?)... let me try to paste again just the part which is connected to python3.

again maybe this is the wrong bug page for this particulat python3 problem, but it is the only one i am subscribed too, when python first started to have problems.

best regards
simon

I looks like you'll need to fetch the .deb for python3 manually and install it with dpkg. That should clear up the mess. It can be found here: https://launchpad.net/ubuntu/+source/python3-defaults/3.2.3-4/+build/3655725/+files/python3_3.2.3-4_all.deb

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 python3-dbg : Depends: python3 (= 3.2.3-2ubuntu1) but 3.2.3-4 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

:(

but thank you anyway....

nice day
simon

I suspect if you sudo apt-get -f install now it will offer to fix the situation
by removing python3-dbg. I'd let it do that and then reinstall it later if
you need it.

@scott -- your suggestion on fortunatelly didnt help - when i did that the result was the same as in comment #13.

But what helped:

your suggestion in comment #14 i manually dl and installed the package via dolphin - right click - open with - qapt package installer

interetingly this way all dependencied were satisfied (resloved) and python3 updated. then i reainstalled python3-dbg which i manually purged b4 via sudo aptitude purge python3-dbg in konsole.

now its ok :)

thank you

simon
