I am using Kali linux as a brand new build and am seeing an issue when running 'apt-get upgrade'. I am running it logged in as the root user so it should not be a privilege issue. I have not modified the sources.list config file either but I always get an error when it attempts to update metasploit. I have listed below my sources.list file contents as well as the error I am seeing when attempting to upgrade. Thanks in advance for anyone who supplies help.

Error I am getting (same error/failure every time):

I figured it out. It was my hardware firewall blocking some of the links I was pulling from. Evidently my Sonicwalls IPS piece doesn't like the metasploit updates along with some of the others. I figured it out by bypassing it altogether and magically everything started working fine. So I will be adding some exceptions to the IPS later this week. Hope this helps anyone else out who has hardware firewalls in place.

Yeah from the error "Connection Failed" i would of presumed a Block for this connection or mis-configuration within your server.

Glad you got it sorted out.
