I use backbox 4.2.0 and when I try to sudo apt-get -f install then see the error like this. I think the problem is in wpascan, Metasploit-framwork and beef-project but I do not know how to fix?
This error also appears when I upgrade or dist-upgrade
thanks...

Hi,

For me that looks like that you have issue will ruby. Try this, one by one:

sudo apt-get install ruby ruby-dev ruby2.1 ruby2.1-dev ruby2.2-dev ruby2.2 --reinstall
sudo apt-get purge ri1.9.1 ruby1.9.1 bundler libruby2.0 ruby2.0 ruby2.0-dev libruby1.9.1 ruby-full
sudo gem cleanup
sudo rm -rf /var/lib/gems/1.*
sudo rm -rf /var/lib/gems/2.0.*
sudo apt-get install backbox-default-settings backbox-desktop backbox-menu backbox-tools --reinstall
sudo apt-get install beef-project metasploit-framework whatweb wpscan setoolkit --reinstall
sudo apt-get autoremove --purge
