I am trying to set up an FTP server on one of my devices that runs

and I selected

as a server. I have installed the software and followed some set-up information I found here . But then I noticed that the service was not running. After trying to find it in via

aux | grep proftpd

I did not succeed. After issuing:

status proftpd.service

I got the following:

● proftpd.service - LSB: Starts ProFTPD daemon
   Loaded: loaded (/etc/init.d/proftpd; generated)
   Active: failed (Result: exit-code) since Tue 2021-04-13 22:58:49 BST; 9s ago

So I dug a little bit here and turns out that no other process runs or binds on port

. So, what could be the issue of the service failing here? Furthermore, by issuing

lsof -i tcp:21

I do not get any response. Also, via

I get the following:

PORT   STATE SERVICE
22/tcp open  ssh
53/tcp open  domain
80/tcp open  http

/tcp

port here. ## Debug via

-nd10
