Removing nginx ...
Stopping nginx: invoke-rc.d: initscript nginx, action "stop" failed.
dpkg: error processing nginx (--remove):
 subprocess pre-removal script returned error exit status 1
Errors were encountered while processing:
 nginx
E: Sub-process /usr/bin/dpkg returned an error code (1)

This occurs because nginx is not currently running, so the invoke-rc.d script fails to "stop" it.

This is fixed by adding --oknodo to the init.d script for nginx.
