Errors during setup

I got these errors when following the quick-installation process.

Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

There were quite a few errors before that if needed I can add as well.

When I direct the browser to my IP address I get the standard:

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

I didn’t set up the ca cert. Is there a chance that broke the install process? Can I go back and do it, and attempt a reinstallation?
