Vagrant failed to initialize at a very early stage: The plugins failed to initialize correctly

Vagrant 2.4.1
Virtualbox 7.0
Ubuntu Noble

I have tried over and over to get my Vagrant box up – installed Vagrant/Virtualbox (which, by the way, 7.1 does not work with Vagrant), completely removed, reinstalled, etc. etc, but when I “vagrant up” I get this:

Vagrant failed to initialize at a very early stage:

The plugins failed to initialize correctly. This may be due to manual
modifications made within the Vagrant home directory. Vagrant can
attempt to automatically correct this issue by running:

vagrant plugin repair

If Vagrant was recently updated, this error may be due to incompatible
versions of dependencies. To fix this problem please remove and re-install
all plugins. Vagrant can attempt to do this automatically by running:

vagrant plugin expunge --reinstall

Or you may want to try updating the installed plugins to their latest
versions:

vagrant plugin update

Error message given during initialization: Unable to resolve dependency: user requested ‘vagrant-vbguest (= 0.30.0)’

At wit’s end.

I have expunged, installed, reinstalled, etc. to no avail.

I have scoured the Web, PLENTY of people with this same error. Any/all “solutions” not working here.

Does anyone have a Clue on how to remedy this situation?

Advice MUCH appreciated,

Mark
