So I've been having this problem so much its became a huge pain, it gets aggravating having to type out such long sentences from my host computer without being able to copy and paste from it, I've tried everything I could find online and I mean everything and none of the solutions seemed to work, I even tried downloading Kali Linux on a Virtual Machine instead of a Virtual Box (Which was a nightmare to setup for me) and it along with a bunch of other features didn't work either (Probably because I'm not good with setting it up), but I didn't care because I mainly wanted it to work on my Virtual Box, I noticed something today though after I reinstalled Kali Linux for my Virtual Box (I figured reinstalling it would do the trick) and it kind of did, at least until i did "sudo apt-get upgrade" then the copy and paste feature stopped working, I've spent awhile dealing with this but I'm fed up, please do your best and leave some ideas, anything, I really just want this to work. Thanks.

Copy & paste is broken in the Guest Additions 6.1.4 r136177. Either downgrade the Guest Additions or install the 6.1.5 test build of the Guest Additions.
