add remove applications help

[kevlar93]

i can not get add/remove applications to work. The button "apply changes" never becomes click able. The updates also fail. What do i do to fix it?

I have an ipcop filtering all the internet. Could that be causing the problems? what websites would i have to allow to allow downloads?

Open a terminal (Applications → Accessories → Terminal) and give

sudo apt-get update && sudo apt-get upgrade
it will ask your for your password.
