VirtualBox Shared Clipboard issue

Question

Consider the following scenario.

VirtualBox: version 6.0.8 r130520 (Qt5.6.2).

Host: Windows 10, Extension Pack installed latest version.

Guest: Fedora 30, Guest Additions installed latest version from Oracle iso (Devices -> insert guest additions cd image). No errors in the logs. Configured Shared clipboard -> Bidirectional from VirtualBox GUI for this virtual machine, then reboot both guest and host.

Here is the configuration file for this virtual machine:

The question: Copy and paste is not working (greyed option in right-click menu), both from host to guest and from guest to host.

The following Q/A does not resolved in my case:

• VirtualBox - shared clipboard not working

• Virtualbox clipboard not working

• Shared Clipboard is not working

• How do I enable the shared clipboard in VirtualBox?

• Bidirectional clipboard not working in VirtualBox

What I'm missing? Thank you

Answer 1

I cannot answer precisely on what is missing but can say how to get it working.

Having no problems with other guests, for Fedora 30 I got it working by:

• remove Guest Additions previously installed from original ISO

  /opt/VBoxGuestAdditions-6.0.8/uninstall.sh

• install them from rpm

  dnf install virtualbox-guest-additions

Answer 2

Thank you.

Updating kernel resolved the issue in my case.

> uname -r
5.1.5-300.fc30.x86_64

Removing and installing Guest Additions from other source was not required.
