I think there is some issue going on.
Code:
apt-get update
apt-get install metasploit
....
Failed to fetch http://http.kali.org/kali/pool/non-free/m/metasploit/metasploit_4.7.1-2013100901-1kali0_amd64.deb  404  Not Found
...
Please note that in sources it tries to find 4.7.1
while
http://http.kali.org/pool/main/m/metasploit-framework/
you can see that they updated it on October 17th with 4.7.2

So, I wonder why apt-get update didn't pick it up?
When I manually downloaded the file and tried to
HTML Code:
dpkg -i metasploit-framework_4.7.2-2013101601-1kali0_amd64.deb
....
dpkg-deb: error: `metasploit-framework_4.7.2-2013101601-1kali0_amd64.deb' is not a debian format archive
WEIRD!!!!

Here is my /etc/apt/sources.list

Code:
deb http://http.kali.org/kali kali main non-free contrib
deb http://security.kali.org/kali-security kali/updates main contrib non-free
When I am trying to manually install from git repo:
https://github.com/rapid7/metasploit-framework
I gotta deal with bunch of issues with installing gems after bundle install. Tried to switch to ruby1.9.3 and it conflicts with postgresql gem (pg) --ahh , so I gave up on that idea

is this an issue on my side or their side with apt-get???
It seems like their pool is not indexed correctly after rapid7 team made a push to kali repo 2 days ago.
