When doing a vagrant up
I get:
Got different reports about installed GuestAdditions version:
Virtualbox on your host claims: 5.0.28
VBoxService in
IN CASE you are using vagrant, from ubuntu's apt repository, uninstall it and step away from the scenario immediately!
sudo apt-get purge vagrant
sudo apt-get clean
sudo apt-get autoremove
Now download vagrant's .deb
by Hashicop from https://www.vagrantup.com/downloads.html install and the error would be gone IN CASE you installed vagrant from apt
clean
and autoremove
is important to prevent the installer from using cached files from apt even when you use the .deb
