Ever since I installed Ubuntu 10.10 I've been getting this error when trying to install ANYTHING via software center and have only been able to install software via Synaptic and apt-get. I 'm sure neither Synaptic or aptitude are running. What is this?

It looks like apt-get are running so paste this on terminal to stop it before using Software Center:

sudo killall apt-get
