Vagrant up failing for VirtualBox provider on Ubuntu-CodePudding

After VirtualBox update vagrant up failing with the following error on Ubuntu:

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["hostonlyif", "ipconfig", "vboxnet2", "--ip", "10.160.0.1", "--netmask", "255.255.255.0"]

Stderr: VBoxManage: error: Code E_ACCESSDENIED (0x80070005) - Access denied (extended info not available)
VBoxManage: error: Context: "EnableStaticIPConfig(Bstr(pszIp).raw(), Bstr(pszNetmask).raw())" at line 242 of file VBoxManageHostonly.cpp

Used versions:

Vagrant 2.2.14
virtualbox-6.1 6.1.28-147628~Ubuntu~eoan
Ubuntu 20.04.3 LTS

CodePudding user response：

I managed to get past the error by downgrading to VirtualBox 6.1.26:

# check the available versions
apt-cache showpkg virtualbox

# stop VirtualBox machines

# downgrade VirtualBox version
sudo apt-get install virtualbox=6.1.26-dfsg-3~ubuntu1.20.04.2

The last command from above doesn't delete virtual machines data.

CodePudding user response：

As of VirtualBox 6.1.28, host-only network adapters are restricted to IPs in the range 192.68.56.0/21 by default.

You can tell VirtualBox to allow additional IP ranges by configuring /etc/vbox/networks.conf. For example, to allow anything in the 10.x.x.x range you could use:

* 10.0.0.0/8
