Error in postfix

Question

I am attempting to run sudo apt-get install -f however it seems that the postfix package is broken:

$ sudo apt-get install -f

However I do not receive an output from:

sudo dkpg --configure -a

I am also getting this error:

$ sudo service postfix status
[sudo] password for learner:
postfix: unrecognized service

Results for sudo apt-get purge(or autoremove) postfix:

dpkg: postfix: dependency problems, but removing anyway as you requested:
 lsb-core depends on lsb-invalid-mta (>= 4.1+Debian11ubuntu6) | mail-transport-agent; however:
  Package lsb-invalid-mta is not installed.
  Package mail-transport-agent is not installed.
  Package postfix which provides mail-transport-agent is to be removed.

Solution

@A.B 's comment fixed my issue, bumping to an answer:

sudo touch /etc/init.d/postfix; sudo apt-get purge postfix

Or if using systemd create a phony systemd service file: scottlinux.com/2014/12/08/… I set ExecStart to /bin/true although it looks like this doesn't apply to the OP.

Personally, I thought you post a little strange; why are you combining both dpkg and apt-get in your package installation? You don't actually ask a question here; So What is your reason for posting this?

Did you try a reinstall?
