Hello,
My subkeys stored on my Nitrokey Start have expired and I have not been able to get the updated expiration dates to stick on the smartcard. I’ve updated the expiration dates with gpg --quick-set-expire <master key fp> 1y <subkey fps>
and then gpg --card-status
shows the updated expiration dates, but if I plug the start into another machine it still shows the old expiration date and gpg commands fail saying they’re expired.
I’ve also tried keytocard
from the edit-key
menu and I get an unusable secret key
error, even though the secret key has been successfully imported.
Am I doing this process wrong? The only way I’ve been able to get the subkeys usable again is to export the public key and reimport it on every machine I use the smartcard on, but it seems like I should be able to update the actual keys on the device itself.
Thanks!
