I got instructions from here, and I found several sites with similar instructions but somethig is wrong with the repositories on 12.04. This should work for 11.10 and previous versions. Any ideas how to install backtrack repos and some back track apps on 12.04? I read about downloading the .deb package for gerix and manually making the same folder structure that gerix uses on backtrack, then manually run the python script, but this way didn't work for me either. How can I get gerix installed and working on my Ubuntu 12.04 system?
