Drag and Drop not working for Ubuntu 20.04 VirtualBox

Question

Host       : Windows 10  
VirtualBox : v6.1.6
Guest      : Ubuntu 20.04

In the same version of VirtualBox I have two different versions of Ubuntu - 18.04 and 20.04.

For Ubuntu 18.04 -
1. Shared ClipBoard - Works fine (Bi-Directional).
2. Drag & Drop - Works fine (Bi-Directional).

For Ubuntu 20.04 -
1. Shared ClipBoard - Works fine (Bi-Directional).
2. Drag & Drop -Not Working at all.
It shows forbidden icon when trying Drag n Drop from Host to Guest. For Guest to Host it shows nothing.

What i tried -
1. Installed VirtualBox Extension Pack v6.1.6
2. Ran - sudo apt-get install build-essential linux-headers-generic
3. Installed GuestAdditions.

But, no luck yet.

Solution

You can only drop inside folders now. You can no longer drop directly on the ubuntu desktop. If anyone has figured out how to enable this.

Please tell! You however can make it land in the desktop by navigating to the Desktop folder in the "Files" app.

Also to install the guest additions cd on a clean ubuntu vbox install now you must first run following commands and install them:

sudo apt install gcc
sudo apt-get install build-essential gcc make perl dkms
reboot

Now you can insert guest additions cd.

Modern versions of Ubuntu have much of the tooling installed by default which may conflict with the GuestAdditions. Also Ubuntu 20.04 just came out, so perhaps wait a bit until there has been an official VirtualBox release after that to give the VirtualBox folks a chance to check everything works. You may in the mean time consider raising an issue to let them know the documentation for Ubuntu may need updating.

Thanks @ThorbjørnRavnAndersen. I have already raised this issue to VirtualBox forum

Virtualbox has not support PPA for Ubuntu 20.04 LTS Focal Fossa. check here download.virtualbox.org/virtualbox/debian/dists

@ajcg Yes, i saw the list. It's not there. Thank You though.

sorry. It is not a PPA. It's a third-party repository
