GuestAdditions version mismatch

Question

when I use this command:

vagrant up

I obtain this error:

[machine1] GuestAdditions versions on your host (4.3.36) and guest (5.0.10) do not match.

how can I update guest addition from ubuntu shell?

Answer 1

Use the vagrant vbguest plugin

Install the plugin:

vagrant plugin install vagrant-vbguest 

Let vagrant up it will install the virtual box client if needed. If you want to force the installation you can run vagrant vbguest --do install

Answer 2

You need to upgrade your VBoxGuestAdditions ISO either by:

• installing/upgrading the package by running:

  sudo apt-get install virtualbox-guest-additions-iso
  

• or by downloading ISO file from this Downloads page.

  Example for macOS:

  sudo wget -O /Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso http://download.virtualbox.org/virtualbox/5.0.10/VBoxGuestAdditions_5.0.10.iso
  

  where version of VBoxGuestAdditions (5.0.10) should match installed VirtualBox binaries.
