Reposting because I forgot system info....
I'm trying to set up a kali netbook so that I can log in with a Yubikey (specifically YB4). The official guide from Yubico states to run "sudo add-apt-repository ppa:yubico/stable", but every time I try to run it the terminal returns "add-apt-repository: command not found".
Trying to resolve that, I tried to install software-properties-common - Nope, "unable to locate package". Most guides tell me to run apt-get update to resolve that, but I've done that multiple times.
How do I add these so that I can finish setting up the Yubikey?
System info:
Kali GNU/Linux 2.0
x64 bit
Acer AspireOne
No logs
