"Machine already provisioned" after "vagrant up"

I installed a vagrant box (oracle db on linux). When I vagrant up, things seem to start up OK other than I get the following as the last few output lines:

oracle21c-xe-vagrant: /vagrant => C:/Users/amc79/source/repos/vagrant-projects/OracleDatabase/21.3.0-XE
==> oracle21c-xe-vagrant: Machine already provisioned. Run vagrant provision or use the --provision
==> oracle21c-xe-vagrant: flag to force provisioning. Provisioners marked to run always will still run.

The database seems to be running although there’s a bit of weirdness when I use command line utilities and I’d like to rule out Vagrant as the culprit.

I aways vagrant halt to make sure I’m not starting a second instance.

I’ve tried vagrant provision as the messages suggest, I’m not exactly sure what it does but it did seem to redownload and reinstall the box. I also updated my Vagrant installation. Neither of these helped.

Thanks in advance.
