DnD not working Mac Host, Ubuntu Guest

[Wags391]

Hello.

I am a new virtualization student. I am just beginning to work with VB on my Mac. I cannot seem to get DnD to work in one instance.

Host- Mac OS X High Sierra 10.13.5
Guest 1- Windows 10
Guest 2- Ubuntu 16.04

I'm able to network share between both.
I can drag and drop bidirectionally with the Windows guest.
I canNOT drag and drop at all with the Ubuntu 16 guest.

Yes, Guest Additions are installed: VirtualBox 5.2.18, Guest Additions 5.2.18

Is there a compatibility issue?

Any help is appreciated.

Look at your guest's "/tmp" directory.
But since DnD has issues (generally speaking), and since you can network share between them, I'd suggest you go with the networking share option.

I have seen how DnD has issues, after all of the searching around on the forum and Google. I'm trying to complete this task for a class assignment, but I feel it is not going to work.

I've attached a screenshot of my /tmp folder. What should I be looking for in there?

There should be a "/tmp/VirtualBox Dropped Files/2018-09-17T22:19:44.358198000Z/Dropped file", but apparently it's not. But I see that you already have mapped the folder. Why not use that?

In any event, if you want to continue with this, we're going to need to see a VM log from a complete VM run:

• Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response.

PS. Next time, please downsize your attached images by 50% (at least), or simply change the DPI to 72. Not everyone is blessed with a HiDPI display.

Hah! I tried to shrink the image! I even went back and uploaded a different one after seeing how huge the original was. Apparently not enough.

We were tasked with mapping shared folders and messing with DnD. I don't particularly need it, but now I'm so far in, I want to know why it won't work.

Log file attached.

Received this error trying to DnD from Host to Guest:
Drag and drop operation from host to guest failed.

Drag and drop error from host (VERR_NO_TRANSLATION).

Result Code: VBOX_E_IPRT_ERROR (0x80BB0005)
Component: GuestWrap
Interface: IGuest {13a11514-402e-022e-6180-c3944de3f9c8}

Received a "Dropping data ..." message when trying to DnD from Guest to Host. Had to X out of that, then the VirtualBox VM "quit unexpectedly."
