rfkill command not found

Question

I'm using Kali on my Raspberry pi I am trying to use airmon-ng but I'm getting the error

root@kali:~/downloads# airmon-ng
Your kernel supports rfkill but you don't have rfkill installed.

To ensure devices are unblocked you must install rfkill.

null    wlan0           ??????          Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter

How do I install rfkill or how else would I avoid this error

I've tried sudo apt-get install rfkill and I got this error

root@kali:~# sudo apt-get install rfkill

E: Unable to locate package rfkill

Solution

Running sudo apt-get update;sudo apt-get upgrade fixed the problem

Like any other software, apt-get install rfkill

@deviantfan I've updated the problem

But it's there: http.kali.org/kali/pool/main/r/rfkill . What's in your /etc/apt/sources.list file? Did you ever do a apt-get update before on this installation?

@deviantfan running apt-get update fixed the problem. Thanks
