When installing nginx, it requires dependent packages like nginx-core, nginx-full, nginx-nasxi, etc. After I install nginx-core and nginx-common, the remaining packagess refuse to install due to conflicts with nginx-core. The 'main' nginx_1.4.6 package is also 'forget' about dependencies on nginx-full, nginx-nasxi, etc. I have the same versions of all nginx packages.
Let me show you what I mean.

What could be causing this issue?
