I am running a:
MBP on 10.14.1 with Virtualbox 5.2.22 installed running Ubuntu 18.04.1 LTS
On the guest I went through and updated everything with sudo apt-get update
and sudo apt-get upgrade
.
Next I installed Vbox extensions and then installed Virtualbox guest additions using this command.
sudo apt install linux-headers-$(uname -r) build-essential dkms
I rebooted the guest between each step. Lastly, I enabled Bidirectional Drag and Drop and Shared Clipboard under Machines and rebooted. After all this I checked if I was able to copy and paste, to my disappointment I still was not able to.
Am I missing anything or does this feature just not work for this setup? Thanks.
