Hi,
Could you tell me which Vagrant provider do use?
If it’s VirtualBox, please see this upstream bug report/ticket which we working with VirtualBox team to add the 8.8 support to Guest Additions of 6…1 and 7.0.
Oh yes. It was little late than usual because we got bunch of updates after the 8.8 release and decided to wait a bit to release cloud images to include these updates.
