I download from VB www the extension pack corresponding to this version,Īnd it is installed: I had access to USB devices.I installed the VB from the repositories of Ubuntu it is now(july2017) I read the VirtualBox User Guide corresponding to the version of VB installed. I had the same problem as you, I'll explain what I've done: Opens standard ".deb"-Installer, respectively virtual box, to take care of the extension pack.

How to install all of that? Double-click. Oracle_VM_VirtualBox_Extension_Pack-5.1.28.vbox-extpack The two offered extension packs are identical (same checksum), pick any: Oracle_VM_VirtualBox_Extension_Pack-5.1.28-117968.vbox-extpack (After abovemtioned 32bit nuisances, ) I got lucky with virtualbox-5.1_5.1.28-117968~Ubuntu~xenial_b Thus it's probably best to download VirtualBox itself and the Guest Additions (now renamed/part of "Extension Pack" it directly from the highest 5.1.x version you can find here: And adding 3rd party repos can get you unintendedly the 32bit version with an obscure error version, see this answer. If you intend to get and use Virtual Box 5.1 (not 5.0), at the time of writing, you won't afaik get it through apt.
