Postfix install problem with Debian

Hello!

I'm trying to setup a postfix installation in Debian.

In the first attempt, I skipped by mistake the initial configuration screen, and I want to re-run it.

I run

dpkg-reconfigure postfix

then it shows the initial config screen with the options to choose from. However, I can't move with the keys and can't choose any option.

Then I try to reinstall it. If I make this:

dpkg -P postfix

It comes with dependency problems:

 mailutils depends on default-mta | mail-transport-agent; however:
  Package default-mta is not installed.
  Package exim4-daemon-light which provides default-mta is not installed.
  Package mail-transport-agent is not installed.
  Package postfix which provides mail-transport-agent is to be removed.
  Package exim4-daemon-light which provides mail-transport-agent is not installed.

¿how is that these packages where not installed alongside with postfix and the initial setup didn't complain?

¿What am I doing wrong?

Any help will be greatly appreciated.

Thanks!

I believe you can't purge (delete) package with

$ dpkg -P

because mailutils depends on it.

You can probably reinstall it with

$ sudo apt-get install --reinstall postfix

but no need do that.

Instead, try to reconfigure it again. If you can't move the keys, you probably have serious problem with terminal emulator. Do you run it in the console or via ssh from another machine?

Done.

I removed mailutils and after that, removed postfix.

Installed postfix again. Then mailutils and it worked!

Thanks a million!
