I have successfully installed a new OS (Ubuntu) on my NItroPad and successfully reset my NitroKey.
When I start the NitroPad and I get to Heads Boot Menu, everything looks OK: HOTP: Success.
However, when I select “Default boot” I get the following message: “No Default Boot Option Configured - Would you like to load a menu of boot options? Otherwise you will return to the main menu”.
I click “Yes” but I get back where I started, i.e. the Heads Boot Menu.
Based on this page of Nitrokey Documentation ( Default Boot - Nitrokey Documentation ) I then selected “Options” and then “Update Checksums and sign all files in /Boot”.
However, when I get on with the process, I get the following message: “Got error ‘Bad counter handle’ (0x45) from TPM_IncrementCounter - Counter increment failed - Failed to sign default config: press Enter to continue.”
This brings me back again where I started, i.e. Heads Boot Menu.
In short, I don’t manage to configure Default boot: I can access Ubuntu only by selecting “Ignore tampering”.
Can anyone help me?
Thanks a lot in advance.
