Drag and Drop not working for Ubuntu 20.04 VirtualBox

[Dusayanta]

Host       : Windows 10  
VirtualBox : v6.1.6
Guest      : 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 -

Code: Select all

sudo apt-get install build-essential linux-headers-generic

3. Installed GuestAdditions.
4. Drag 'n' Drop is set to Bi-Directional

But, no luck yet.

First thing to consider is that Ubuntu 20.04 is currently 'brand new' and so nothing can be guaranteed to work fully on a version of VirtualBox that that was released a couple of weeks earlier.

You could try installing an older version of the Guest Additions, e.g. 6.1.4, to see if there is any difference in behaviour caused by regressions - There should be no need to downgrade the VirtualBox installation itself. Alternatively, wait for the next Test Build/Full Release of VirtualBox/Guest Additions which should then include any known changes required by new Linux releases, as well as fixes for known issues - there have been several reports of glitches with 6.1.6 Guest Additons, but they seem to vary depending on the Host (Mac/Windows/Linux). - See here: viewtopic.php?f=3&t=97686 & the Public Bugtracker: https://www.virtualbox.org/wiki/Bugtracker

Does this needs to be added in the Bug Tracker List? If yes, who is going to add it?

[scottgus1]

Not yet on the Bugtracker please. We need to confirm a few things first.

Start the guest from full power off, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.

Please zip and post a guest vbox.log, using the forum's Upload Attachment tab.

Any progress on this? I'm facing the same problem.
Win 10 host, Ubuntu 20.04.1 LTS VM, GuestAdditions installed, Bidirectional copy-paste works in both directions, shared folder works, drag & drop fails in both directions.

I'm facing the same problem.

When you consider posting a going topic it is helpful to read the topic and apply the suggested advice first.

I suppose the answer is no, then?

[scottgus1]

I reckon so, for those that won't apply the posted advice.

I thought if there were progress made on this issue, I could avoid trying an older version to see if things change. I also skipped considering whether ubuntu 20.04 is brand new, since that suggested advice as a few months ago.

I believe I've done the same as the OP otherwise.

I believe I've done the same as the OP otherwise.

That is correct, because the OP didn't follow the suggested advice either.

Have you read the whole topic?
