The latest version of evilgrade does not work properly, so don't download evilgrade using the git clone command in the video, instead download it from the following link: https://www.dropbox.com/s/vr1mpesah1ybuai/evilgrade.zip?dl=1 Then go to the downloads and boule click evilgrade.zip to uncompress it. Now open a terminal and run the following commands: cd /root/Downloads/evilgrade/ cpan Data::Dump cpan Digest::MD5 cpan Time::HiRes cpan RPC::XML cp -r isrcore /etc/perl Now the tool will work, it might display an error about Gnu.pm this is a known bug with evil-grade, if its annoying you the you can get rid of it using the by removing that lib using the following command apt-get remove libterm-readline-gnu-perl Just make sure you re-install it after you're done in case it is needed by other tools apt-get install libterm-readline-gnu-perl
