On my daily working PC the VirtualBox Manager was installed on the ISO download on Oracle website. I trust that this VirtualBox Manager was installed on repo. If you can, then it seems that you installed it from a repository, which escapes me how you did it. In order to verify that indeed is installed from repo, then you can open synaptic, search for virtualbox and check if there is an option to update it (which I doubt). Your version is one of the latest ones of virtualbox. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 3.0 support in the VM settings (VERR_NOT_FOUND). Implementation of the USB 3.0 controller not found!īecause the USB 3.0 controller state is part of the saved VM state, the VM cannot be started. But I have no idea which package on the repo is correct? I suppose it needs to install the guest-addition. Just installed Ubuntu 18.04 VM and copy/paste between Host and VM doesn't work. Therefore some VMs were built on Oracle version and others on Ubuntu repo version Then I changed to install it on Ubuntu repo. IIRC I ran VirtualBox download on Oracle website first.

Sorry I couldn't recall when it was installed.

I supposed VirtualBox manager was installed on Ubuntu repo. This is a spare PC only used occasionally. I suppose that this helps, unless I have not understood correctly your issue. From there you will be able to find the extension pack you are after.Īs far as the guest additions are concerned when your guest os is on and running, from Desktop there is:Īnd from there, as root, we install the n, which corresponds to the version of your VB. I'm using VB myself, yet the installation has taken place from the website of oracle:Īctually, the link I have provided is about older builds of VB, like the one you are using.
