I just received my Nitrokey Storage, and I’ve been setting it up…
I’ve had the same results trying this from OS X and from Linux
I do the usual routine to transfer my keys to the device:
$ gpg --edit-key <key>
gpg> key 1
gpg: KEYTOCARD failed: General error
I’m also seeing errors where he Nitrokey App shows the Nitrokey as being added/removed every few seconds – the key itself isn’t moving. GPG seems to see similar behavior, as --edit-card will occasionally think the Nitrokey has been unplugged.
I’ve tried updating to the firmware in firmware_V0.43.zip
Does this sound like a hardware or firmware issue?
