i tried to update the firmware of my Nitrokey 3 following the instructions in Firmware-Aktualisierung — Nitrokey Documentation. I downloaded the *.sb2 image and then tried to execute the command
nitropy nk3 update <SB2_IMAGE>.
I got the following result "Nitrokey tool for Nitrokey FIDO2, Nitrokey Start, Nitrokey 3 & NetHSM
Usage: nitropy nk3 [OPTIONS] COMMAND [ARGS]…
Try ‘nitropy nk3 --help’ for help.
Error: No such command ‘update’."
Help indeed does not show the update command. Any idea, what went wrong?
