Empty trellis provision: Task failed: Incorrect sudo password

For testing purposes I provisioned an empty Ubuntu 24 LTS VM with Trellis.

The initial provision worked fine, subsequent provisions fail with
Task failed: Incorrect sudo password

The default `vault.yml` and credentials are used:

vault_users:

  - name: "{{ admin_user }}"

    password: example_password

    salt: "generateme"

The defaults, albeit insecure and so on, should still work?

I tried the password “example_password” manually for sudo and it works fine.
