Why apt-get purge wants to install packages while I use --no-download and --no-install-recommends?

Question

I am using Debian but I think this can be easily posted here.

I have already uninstalled openoffice packages from my Debian machine but somehow apt-get put abiword in his place. Now I would like to get rid of it as well but when I try to apt-get purge abiword I get this :

monkey@debVirtual:/$ sudo apt-get purge  abiword

I have tried also both apt-get purge --no-download abiword abiword-common and apt-get purge --no-install-recommends abiword abiword-common but the get more or less similar output:

monkey@debVirtual:/$ sudo apt-get purge --no-download  abiword abiword-common

Answer 1

I'm guessing something on your system is depending on openoffice.org | abiword.

And yes, I see that gnome does so on my system:

$ apt-cache show gnome
...
Depends: ... abiword (>= 2.8) | libreoffice-gnome ...
