New Ubuntu box does not execute the vbguest plugin

[BenjaminLeibinger]

After upgrading the vagrant ubuntu box to version 1.0.4 the vbguest plugin does not run his installer. So the Guest Additions are not installed / updated. Without this, its not possible to properly start the vm and mount the vagrant dir.

my setup:

• Host OS Ubuntu 20.04
• virtualbox 6.1.26 (also testet with 6.1.32)
• Vagrant 2.2.19
• Vagrant plugins: vagrant-hosts-provisioner (2.0, global), vagrant-hostsupdater (1.2.4, global), vagrant-vbguest (0.30.0, global)

Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem "vboxsf" is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attempted was:

mount -t vboxsf -o uid=900,gid=900,_netdev vagrant /vagrant

The error output from the command was:

/sbin/mount.vboxsf: mounting failed with the error: Invalid argument

Its possible to manually trigger the guest additions installation by running:

vagrant vbguest hausweblocal --do install --no-cleanup

After downgrading the vagrant box to Version 1.0.3 everything works as expected:

vagrant box remove geerlingguy/ubuntu2004
vagrant box add --box-version 1.0.3 'geerlingguy/ubuntu2004'

And then run vagrant up again:

Hmm... /sbin/mount.vboxsf: mounting failed with the error: Invalid argument I wonder if there's a version mismatch somewhere?

I also had in one run the following addition in the output:

Got different reports about installed GuestAdditions version:
Virtualbox on your host claims:   6.1.6
VBoxService inside the vm claims: 6.1.32
Going on, assuming VBoxService is correct...

and the Virtualbox on your host claims: 6.1.6 could be verified by:
