Bojan's questions

When I try to do the system update I get this:

How do I fix this?

Is there any way to make Liferea faster in fetching feeds from Google Reader? It certainly could be a quality rss reader but in my case it's painfully slow.

Every time I change effects in Compiz my top bar gets screwed and I have to log out and log in again. Is it normal?

Can't install Simple Compiz Config Manager. Is it normal?
