12.04 - Problem with broken package system

Yesterday I found that the Code::Blocks 13.12 on my Ubuntu 12.04 LTS is broken, when I clicked the icon, it reacted nothing, so I tried to reinstall.

I tried to use the instructions from codeblocks' official website to install codeblocks
http://wiki.codeblocks.org/index.php?title=Installing_Code::Blocks_nightly_build_on_Ubuntu

but it failed

yuyue@ThinkPad:~/Downloads/debian-stable/amd64$ sudo dpkg -i *.deb

    Errors were encountered while processing:
     amd64.deb
     codeblocks
     codeblocks-contrib
     codeblocks-contrib-dbg
     codeblocks-dbg

then I tried this

sudo add-apt-repository ppa:pasgui/ppa
sudo apt-get update
sudo apt-get install codeblocks

and after this I installed Code::Blocks 13.12 successfully, but when I opened it I found that I can't build or run any files(seemed to have problem with plugins)

Errors were encountered while processing: codeblocks codeblocks-contrib codeblocks-dbg codeblocks-contrib-dbg E: Sub-process /usr/bin/dpkg returned an error code (1) 

and then I found my package system was broken...
I don't have Synaptic Package Manager on my computer,
I followed this instruction(from Package system is broken. How to fix it?)

After you get that error, try sudo apt-get -f install to force an

install of the files that didn't get loaded because of the error.

Then try sudo apt-get update again, sudo apt-get -f install back and
forth until only the package that has the error is left.

sudo dpkg --configure -a

and clean the cache

sudo apt-get clean

it looks like that nothing effective was done.
I opened Ubuntu Software Center, and it notified me to download something to repair the package system, I did it, and in the end I found my package system is still broken...

Is there anyone who have a good idea about what to do next?
