"OK" was only my acknowledgement of your instruction or suggestion.
Not a confirmation of success.

Debian 10 allows me to install one or the other but not both.
I removed inetutils-inetd and installed openbsd-inetd.

peter@joule:~$ dpkg -l | grep telnet /etc/inetd.conf
telnet		stream	tcp	nowait	telnetd	/usr/sbin/tcpd	/usr/sbin/in.telnetd -a none -E /bin/bash

Executes with no report to the terminal.

> 4) telnet localhost

peter@joule:~$ telnet localhost
Trying ::1...
Connected to localhost.
Escape character is '^]'.
telnetd: a: unknown option
Usage: telnetd [-debug port] [-D (options|report|exercise|netdata|ptydata)]

Connection closed by foreign host.

Appears the -a option is not available.
