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

I seem to have encountered problems with the software-center, and the general removal, or installation of packages, even through synaptic package manager. And I am often getting system error messages

When I try to sudo apt-get update/upgrade I often get errors, and if I try to re-install the software-center it fails with the error
"Errors were encountered while processing: /var/cache/apt/archives/software-center_5.2.7_all.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)" I am completely stuck on what to do, I've tried sudo apt-get purge software-center and others and none seem to work.

This is the full output of "sudo apt-get install -f software-center"

All Help Appreciated

Try these here:

sudo dpkg --configure -a

sudo apt-get install -f

[Spyderkid]

I tried them and noticed no difference :/

[wojox]

sudo -i
cd /var/cache/apt/archives
dpkg -i --force-overwrite software-center_5.2.7_all.deb
dpkg --configure -a

[Spyderkid]

Thanks, that's seemed to sort out the software-center.

Much appreciated
