[debian] How to install telnet

I am trying to install telnet and test it
I want to use it to telnet-client.

I gave the install command as follows. However, they were not installed.

$ sudo apt-get install xinetd
$ sudo apt-get install telnetd

Below is the message when executed.

How can I install telnet client and test it?
Please. help me


Try -

apt-get install telnetd

/etc/init.d/inetd restart

$ telnet server-ip-address

Perhaps - but I am not an expert on Debian

@taek8461, Make sure you update the apt cache:

sudo apt update
sudo apt install telnet
