Issue while installing package

Hi all,

This is my first time using Admissions Connect and I am trying to install it on my sandbox org. during the installation process I encountered an error (https://install.salesforce.org/products/admissions-connect/1.20/install-and-build-community/jobs/lQE4zyl) How can I solve it? If I try to reinstall without the step that is failing (Which is optional) the installation reaches the last step where it fails again so I am not sure if both issues are related. Any input would be appreciated, thanks!
