No apport report written because the error message indicates its a followup error     from a previous failure.

 python3.3

E: Sub-process /usr/bin/dpkg returned an error code (1)

and I can't turn off my computer...

I guess I did not install correctly python 3.3, but how can I repair it?

Edit: I tried apt-get --reinstall install python2 python2-support
but I got: the same error

EDIT: More information

on my system:
Linux Mycomputer 3.5.0-34-generic #55-Ubuntu SMP Thu Jun 6 20:20:19 UTC 2013 i686 i686 i686 GNU/Linux

dpkg --print-architecture   

i386

I used to have ubuntu 12.10.
My problem occured when I tried upgrading it to 13.04.
I had a error message telling me the process stoped because there were too many errors.

I then tried to run sudo apt-get update && sudo apt-get upgrade but encountered the error above.

I had a similar problem a few months ago when I mistakenly deleted python2 from my computer. I then could not turn off my computer by clicking on the icon (it does not respond) and turning off. The only way was to force it to shut down manually. When I turned it on again, I just had an empty desktop and could not do anything. This was fixed by reinstalling the whole system.

Searching on the internet, I tried several commands:

sudo dpkg --configure -a

which resulted in
