This is not a bug. This is a conflict between the nginx.org repository and the Ubuntu repositories.

Either completely remove the nginx.org repository and the installed NGINX packages from there (sudo apt-get purge nginx) and install the Ubuntu Repository versions, or use only the Ubuntu Repository versions. Do not mix and match them.
