For me, upgrading to VirtualBox 4.3.2 and upgrading the VM to its Guest Additions (I had previously used the Ubuntu virtualbox-guest-utils package, which in the latest 4.2.16-dfsg-3 still contains this bug) allows me to successfully mount *and access* my shared folders.
However, during boot, I still get the error described here: http://askubuntu.com/questions/365346/virtualbox-shared-folder-mount- from-fstab-fails-works-once-bootup-is-complete An error occurred while mounting [...]. keys:Press S to skip mounting or M for manual recovery -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1239384 Title: Unable to access shared folders in Virtualbox from 13.10 guest.
