I'm new on Solus and I would like to use my yubikey for gpg use. My gpg keys are on my yubikey 4 and normally, on other distribution, I use the command gpg --card-status to see my keys and to make gpg reach them. Then, I'm able to use e.g. Enigmail and it only asks for the pin of my yubikey. But with Solus, the gpg --card-status command gives me the following feedback:
gpg: selecting openpgp failed: Aucun périphérique de ce type
gpg: la carte OpenPGP n'est pas disponible : Aucun périphérique de ce type
(Sorry, it's in French, but basically, it says "no such device of this kind".)
Should I install an additional package? Is there anything that I can do?

Thank you very much in advance for your help!

Is ccid installed? If not done yet, you can install yubikey-manager and check from the app.

    Hi, and thanks for your very quick reaction!
    kyrios it worked! Installing yubikey-manager was indeed the first thing to do but since I use my yubikey only for gpg, I didn't thought I needed it... Anyway, thank you so much! Cheers
