How to install latest version on Kali Linux

[altang78 at gogo.mn]

Hi all,

I'd like to know easiest way to install the latest version on Kali Linux. I
need to save VPN credentials so that I'm trying to install latest version.
The latest one is not there in APT repository, so I'm seeking PPA for the
latest one. I tried to install from the source and it was truly
complicated, too many dependencies. Any input would be highly appreciated. 


Regards,
Aggie
