[Towhidn]

backtrack V5 RC1 on VMware

root@bt:~# tctrace
The program 'tctrace' is currently not installed. You can install it by typing:
apt-get install irpas
You will have to enable the component called 'multiverse'

when I try to install it:

root@bt:~# apt-get install irpas

irpas is already the newest version.

I also tried uninstalling & installing it again. problem remained
p.s. I hate this forum's "Image Verification" , worst ever
