Yubico Forum

I just got a yubikey4 and while it produces a one time password with a touch, I was wondering what other capabilities it had so I installed yubikey-personalization-gui on my Mint 17 box.

I've also tried on Debian with the same result.

It says "No YubiKey Inserted"

It occurs to me that perhaps it isn't designed to work with yubikey4.

I apologize if I missed documentation somewhere stating this, but they key itself came with nothing, but the protective sleeve. The online manual is pretty terse as well.

The version installed says
Application version 3.1.14
Library Version 1.14.1

I've also tried with 3.1.24 on the Debian box.

The library version is too old - https://developers.yubico.com/yubikey-p ... ility.html

Linux Mint can use the Ubuntu PPA, so it's best to follow that method.



(I think instead of running the third command, since you already installed the app, you should be able to run "sudo apt-get upgrade" instead)

This will pull all dependencies and you should be able to use it with the YK4. At this point it's also a lot easier to install other Yubico apps like Yubico Authenticator. For example:

If you're planning on implementing any smart card functionality or U2F, make sure to also run the following command and reboot:

Thank you for your help. It looks like it only works as root.

$ ykpersonalize -v
USB error: Access denied (insufficient permissions)

I looks like I need some udev rules to set up permissions. There are some udev rules for something at https://developers.yubico.com/yubikey-personalization/ but they don't seem to address permissions. Perhaps since it shows up as an HID device.

Perhaps this is by design.
