Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

Do you have Apache or some other service set up and running on Port 80 already?

If so, disable that service (or at least stop the service) before running `apt-get install -f` or similar to finish configuration. You have a "cannot bind to port" error as a result of something else being bound to the port already, which does not indicate a bug in this package.

(Check the output of `systemctl status -l nginx` to see the error messages which point out the failure code.)
