I'm running v1.0.9 64-bit with kernel 3.12-kali-amd64 and get errors when I try to apt-get update
First tried command line interface and got errors. Below is the console output, gpg key, & sources list.

I updated 2 desktops without problem in the past 2 days. The machine I'm having trouble with is a thinkpad X1 carbon.

Using the software update gui gives a "failed to process request" error:
