Unable to start mosquitto on raspberry pi buster – Debian

Was trying to install npm and got message "ERROR: npm is known not to run on Node.js v11.4.0"
So unsinstalled nodejs and then mosquitto got stucked.
I can not start it .

And this is my mosquitto.conf file

include_dir /etc/mosquitto/conf.d

listener 1883
allow_anonymous true

I have manually added ,listener and allow, to see if that would make any difference. But same result<

If I run, I get illegal instruction. Do not understand why…

pi@raspberrypi:~ $ sudo /usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf
Illegal instruction

Also can not get version since I get illegal instruction….

pi@raspberrypi:/etc/mosquitto $ mosquitto -v
Illegal instruction
pi@raspberrypi:/etc/mosquitto $ mosquitto -h
Illegal instruction

Description: MQTT version 3.1/3.1.1/5.0 compatible message broker
This is a message broker that supports version 5.0 and 3.1.1 of the MQTT
protocol.
.
 MQTT provides a method of carrying out messaging using a publish/subscribe model. It is lightweight, both in terms of bandwidth usage  and ease of implementation.

Inside the file I have

#deb [trusted=yes] http://archive.raspberrypi.org/debian/ buster main
deb http://mirror.ufam.edu.br/raspbian/raspbian/ buster main contrib non- free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://archive.raspberrypi.org/debian/ buster main

Any idea how to bring back to life mosquitto?
