It looks like a recent change with the way that "next" urls are returned has broken installs.

Ansiblefile:

site 'https://galaxy.ansible.com/api/v1'

role 'sensu.sensu'

librarian-ansible install

First request:

https://galaxy.ansible.com/api/v1/roles/?name=sensu&format=json

returns 200

Next request:

https://galaxy.ansible.com/api/v1//roles/?format=json&name=sensu&page=2

returns 404

Could not read package from galaxy API.

The extra slash breaks it.

It would be helpful if the "Could not read package error" included the url and status.
