I know its a common issue, but I couldn't find a solution online.

I downloaded the ISO (32 bit) from here: http://lubuntu.net/blog/lubuntu-1610-yakkety-yak-released

I mounted the guest additional from input -> insert guest additions CD image.

Then I started VBoxLinuxAdditions.run.

I enabled shared clipboard and drag and drop, neither work Nor does the shared folder I tried to mount.

I figure the problem is something with the guest additions - but every time I try to install again, it says that its updated.

When I try running modprobe vboxsf , as I have seen suggested, I get ERROR: could not insert 'vboxsf': Operation not permitted.

Also used sudo gpasswd -a username vboxsf to add myself to the user group, it said it worked but then again, the above operations still aren't working.

modinfo vboxsf output:

  • Can you post all the error messages? – Arun Jun 9 '17 at 18:38
  • Did you log out/in after putting username in group vboxsf? That'll fix your shared folder problem. Clipboard and drag/drop has always been a problem. Are you running VB 5.1.22? – heynnema Jun 9 '17 at 19:08
  • @Arun For which commands? The only real 'error' I encountered is the modprobe one, but still, it doesn't work. – Gray Jun 9 '17 at 19:26
  • You mean modprobe: FATAL: Module vboxdrv not found.? – Arun Jun 9 '17 at 19:28
  • @heynnema I restarted the VM, but I still don't have access to the shared folder in /media/shared_name, even tho auto-mount is on. I'm not sure how to check the VB version? – Gray Jun 9 '17 at 19:29
