I'm trying to upgrade a project of mine that currently uses vuforia 8.1
If I download unitypackage from vuforia's site I get:
An error occurred while resolving packages:
has invalid dependencies:
com.unity.ugui: Package [firstname.lastname@example.org] cannot be found <---- makes sense, project is with unity 2018.3.7f1
A re-import of the project may be required to fix the issue or a manual modification of J:/unities/vatra9/Packages/manifest.json file.

Does vuforia 9 only works with a specific unity version?
