I am running a VirtualMachine (6.0.14) on MacOS 14.10.6, with Ubuntu 20.04 installed in the VM. I think I have installed the Guest Additions, and under Settings -> General -> Advanced I did select Bidirectional for Shared Clipboard and Drag'n'Drop.
However, when I copy some text in the host system (MacOS) by using CTRL-C or mouse right click -> copy, I am not able to paste that text into the Terminal on the client system (Ubuntu) running in the Virtualbox (neither right-mouse click is working, nor CTRL-V).
I also tried to run (see here):
sudo VBoxClient --clipboard
but this did not solve my problem.
The kernel module seems to be loaded, as I get some output from this command
lsmod | grep vboxguest
So what else can I try?
