    Repeated output with apt-cache show

    When I run
    apt-cache show nginx
    I get

    Description-en: small, powerful, scalable web/proxy server
     Nginx ("engine X") is a high-performance web and reverse proxy server
     created by Igor Sysoev. It can be used both as a standalone web server
     and as a proxy to reduce the load on back-end HTTP or mail servers.
     .
     This is a dependency package to install either nginx-full (by default) or
      nginx-light.

    but it's printed twice. The same happens with apt-cache show firefox.

    Other ones work fine: apt-cache show with geany or gedit or medit or google-chrome-stable give the data just once (as expected).

    Does anyone else see the same?

    This is on 13.10.

    Just tested with firefox, yes, it outputs twice ..
    Edit1 :
    Code:
    dpkg --print-avail firefox
    has only one output.
    Edit2 : http://lists.debian.org/deity/2001/04/msg00038.html. Old thread but Matt Zimmerman says : "Note that both erlang and erlang-base appear twice (apparently because they exist both in non-US and in the main archive)" so I guess it could be normal

    How many are listed when you run
    apt-cache policy "package" ?

    Yes, in the present case, they're in saucy-updates and in saucy-security.

    I thought I had messed up something because I'm learning a bit about Bash and maybe some command I entered did something weird when I wasn't looking
