In the same thread line I'm encountering another issue when I'm trying to install it from apt-get :

apt-get install metasploit
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following NEW packages will be installed:
0 upgraded, 1 newly installed, 0 to remove and 2 not upgraded.
Need to get 277MB of archives.
After this operation, 0B of additional disk space will be used.
Get:1 revolution/testing metasploit 4.4.0-bt2 [277MB]
Get:2 revolution/testing metasploit 4.4.0-bt2 [277MB]
Fetched 276MB in 3s (79.3MB/s)
Failed to fetch http://64.repository.backtrack-linux...-bt2_amd64.deb Hash Sum mismatch
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Firstly I've done:

1. apt-get purge metasploit

2. apt-get update --fix-missing

However, the issue still shows as I've described earlier.

Any thoughts?

Thanks much....
