You can do it much easier with [NitroKey](https://www.nitrokey.com/),
which is also open source. It presents itself as a GPG smartcard, no
need for all this weird extra stuff.

Base keys are 29euro

huh, that's much better priced. Does this mean GPG would need to be
installed on the OS?

Sorry, I'm ignorant about these key things...

Yeah the yubikey also presents itself as a GPG smart card which of
course you can then use for SSH by making your SSH agent env variable
point to the gpg agent. I use it for SSH access to my servers. It's
not hard to set up. I think the author just wanted to avoid gpg.

Personally I can't go with nitrokey because they don't have u2f and
gpg on the same product despite having separate products that do each.
