An error while executing `VBoxManage` while installing r8 VM

[arham-jain]

I am trying to install a LAMP VM using r8 and vagrant. After the download, on executing vagrant up the following error is encountered. Also, Windows keeps prompting Do you want to let Virtual Box make changes on the device?. Even allowing it does not work. Based on another answer I also tried to reload Virtual Box but that doesn't seem to work. I do have another VM installed on Vagrant, which is shut down.

Bringing machine 'default' up with 'virtualbox' provider... ==> default: Checking if box 'scotch/box' is up to date... ==> default: Clearing any previously set network interfaces... There was an error while executing VBoxManage, a CLI used by Vagrant for controlling VirtualBox. The command and stderr is shown below.

Command: ["hostonlyif", "create"]

Stderr: 0%... Progress state: E_INVALIDARG VBoxManage.exe: error: Failed to create the host-only adapter VBoxManage.exe: error: Assertion failed: [!aInterfaceName.isEmpty()] at 'F:\tinderbox\win-5.2\src\VBox\Main\src-server\HostNetworkInterfaceImpl.cpp' (76) in long __cdecl HostNetworkInterface::init(class com::Bstr,class com::Bstr,class com::Guid,enum __MIDL___MIDL_itf_VirtualBox_0000_0000_0038).
