VirtualBox Shared Clipboard not working on Ubuntu Budgie 18.04 VM guest

VirtualBox Guest Additions are installed and Shared Clipboard (Bidirectional) option selected. Even tried to reboot still not working. Any hints how to fix is appreciated. Note that Ubuntu 18.04 (Gnome) and Ubuntu 18.10 LXQt is working the same Windows 10 host.

[6/18/2018] Most be getting old. I assumed VirtualBox guest additions was installed as the VM window can be resized. Anyway, installed guest additions and copy/paste worked like a charm.

(Momentics:): GLib-CRITICAL **:: g_base64_encode_step: assertion 'in != NULL' failed

Running QNX Momentics (qde) from the console on Ubuntu 18.04 shows a lot of error message but it seems like it does not affect functionality of the application. Below is an example of the error message I am seeing.

(Momentics:3535): GLib-CRITICAL **: 23:28:28.692: g_base64_encode_step: assertion 'in != NULL' failed

To get rid of the error message, do the following:

$ sudo apt install libcanberra-gtk-module
export SWT_GTK3=0
~/qnx/qnxmomentics/qde
