I want to install VirtualBox 5.1.24 .

Hi ,
I want to install VirtualBox 5.1.24 .
Please Help me …
I tried to do Nested Virtualization , like him .

At first , I tried to do this in konsole panel .

sudo apt-get install virtualbox linux-headers-$(uname -r)

Maybe , installed VirtualBox 4.6 .
I tried to install Windows 7 in it .
But , I could not install it …

I have heard that VirtualBox under 5.0 version cant do Nested Virtualization .

So , I tried to install The Newest version 5.1.24 .
I have removed the old version . and
I downloaded virtualbox for debian 8 jessie i386 .

I put it into VirtualBox folder of Desktop .
And I have done this

sudo dpkg -i /home/user/Desktop/VirtualBox/virtualbox-5.1_5.1.24-117012~Debian~jessie_i386.deb

But , some error appeared …
I tried to run VirtualBox , but operation window didnt appeared .
So , I couldnt run Virtualbox …

So ,I have deleted Whonix , and installed it , again .
Please tell me the way to install VirtualBox 5.1.24 .
I want to try to succeed Nested virtualization .
Windows7 => Whonix Workstation => Windows 7

Should I use backport ??


Is it safe to use backport ??

whonix 13 now doest work properly witha newst Vbox version. gateway connection wont work and also vbox kicked from being inside debian repos.and i dunno if this will be fixed or not witha new whonix version.
