I have VBox 6.1.30 with compatible 6.1.30 Extensions and Guest additions installed on the Ubuntu client.
However, I cant get cut-and-paste, drag-n-drop or screen resizing to work (though I can get file sharing to work by manually mounting the vboxsf drive).
This used to work before under earlier 6.1.x versions but I am not sure what changed other than upgrading.
I compiled guest additions as per the instructions by mounting the iso on the client and manually running 'VBoxLinuxAdditions.run' and restarting both the Ubuntu VM client (as well as the Windows host for good measure).
The /var/log/vboxadd-install.log seems to show a successful compilation:

Running 'lsmod' shows that 'vboxguest' is installed.
Similarly, my syslog shows:
