Tested on: Host: Windows 10 Enterprise (1803) with VirtualBox 5.2.20 Guest: Ubuntu 18.10 (Cosmic Cuttlefish) Goal : Copy/paste text from/to Ubuntu 18.10 from/to Windows host Solution: This is not absolutely necessary but it is a good practice to update Ubuntu 18.10 to the latest using a terminal, like: $ sudo apt update $ sudo apt upgrade $ sudo apt autoremove I would advice to reboot the machine at this point so that we will be running the latest kernel. The next command may also pick the wrong version of the kernel headers if the machine(VM) is running the older version of the kernel. Now, install dkms so that VirtualBox guest additions can be compiled as part of the kernel, like: $ sudo apt install dkms Now mount VirtualBox guest additions, this will be done from the external/host UI of the VirtualBox guest VM. For example, click on Devices | Insert Guest Additions CD Image... Now head into the VM and do: $ cd /media/<username>/VBox_GAs_5.2.20 $ sudo

Tested on: Host: Windows 10 Enterprise (1803) with VirtualBox 5.2.18 Guest: Kali Linux 2018.3a Goal: Copy/paste text from Kali Linux from/to Windows host Solution: This is not absolutely necessary but is a good practice, update Kali to latest version using a terminal, like: :/# apt update :/# apt upgrade :/# apt autoremove Sometimes this is not enough to bring Kali to the latest and greatest, you may have to also upgrade it, like: :/# apt full-upgrade I would advice to reboot the machine at this point so that we will be running the latest kernel. The next command may also pick the wrong version of the kernel headers if the machine(VM) is running the older version of the kernel. Now, install dkms so that VirtualBox guest additions can be compiled as part of the kernel, like: :/# apt install dkms Now mount VirtualBox guest additions, this will be done from the external/host UI of the VirtualBox guest VM. For example, click on Devices | Insert Guest Additions CD

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.

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
