I have just set up Ubuntu 12.04 in a VirtualBox (v. 4.3.15) under windows 7 host.
I set clipboard and drag-and-drop to be directional.
I can copy and paste from the Ubuntu to the windows side.
Copying from Windows to Ubuntu comes out empty.
I have installed Guest Additions. The only thing I found in posts from people about clipboard not working, I tried...
$ sudo killall VBoxClient
$ sudo VBoxClient-all
$ ps -ef | grep -i vbox
root 806 1 0 08:20 ? 00:00:00 /usr/sbin/VBoxService
root 2444 1 0 08:55 ? 00:00:00 /usr/bin/VBoxClient --clipboard
root 2455 1 0 08:55 ? 00:00:00 /usr/bin/VBoxClient --display
root 2460 1 0 08:55 ? 00:00:00 /usr/bin/VBoxClient --seamless
root 2465 1 0 08:55 ? 00:00:00 /usr/bin/VBoxClient --draganddrop
me 2470 2376 0 08:57 pts/3 00:00:00 grep --color=auto -i vbox
What else can I try ?
Edit: Even though I selected bi-directional drag-and-drop, it does not work in either direction. I did not test that initially since I mounted a share and been copying files through command line... But may be relevant information the fact that, while mounting manually a share worked, I cannot browse through the network folders, I get an error "Unable to mount location. Failed to retrieve share list from server". I do not particularly care to solve that issue unless it is a cause of the copy/paste problem, which is very annoying.
