Install Failes to resolve set of packages

[staulien]

I selected the following from your site to create a install package and it will not work. I have tried other options and it works fine but this set doesn't.

Options Selected:
Build Summary
Region
North America

Distribution
Lightning

Payments
Paypal

Shipping
Flat Rate
UPS
FedEx
Postcode

Taxes & Accounting
Custom Taxes

Catalog
Database Search

Data Migration
None

When I put the files (I have attached) into my web folder and run 'composer install' I get the following message. I have also tried to 'composer update' to see if it would resolve some dependencies however it didn't.

Error Messages:
