Ubuntu¶
Plommitud riistvara kontrollimine¶
If you have ordered the unit with the option “sealed screws and sealed bag”, please verify the sealing before unpacking. If you do not know what this means, skip this section.
Turvaline stardiprotseduur¶
With the NitroPad and NitroPC, malicious changes to the BIOS, operating system, and software can be easily detected. For example, if you left your NitroPad in a hotel room, you can use your Nitrokey to check if it has been tampered with while you were away. If an attacker modifies the NitroPad’s firmware or operating system, the Nitrokey will detect this (instructions below).
Each time you start the NitroPad or the NitroPC, you should - if possible - connect your Nitrokey. If the Nitrokey is plugged in and the system has not been modified, the following screen will appear when it is turned on.

The box marked in red contains the information that the BIOS has not been changed and that the shared secret of the NitroPad or the NitroPC and the Nitrokey match. But this information is not sufficient, because an attacker could have faked it. If at the same time the Nitrokey also flashes green, everything is fine. An attacker would have to have had access to the NitroPad or NitroPC and Nitrokey to achieve this result. It is therefore important that you do not leave both devices unattended.
If the information on the NitroPad or NitroPC does not match the information on the Nitrokey, the background would turn red and the message “Invalid Code” would appear. This could indicate that manipulation has taken place.

Seda, kuidas käivitamisprotsess võib välja näha, kui süsteemi on muudetud (näiteks pärast uuendust) ja millised veateated võivad muidu ilmneda, on kirjeldatud allpool.
Nõuanne
The NitroPad and NitroPC can also be started without the Nitrokey. If you don’t have the Nitrokey with you, but are sure that the hardware has not been manipulated, you can boot your system without checking.
Ümberehitus Ubuntu 24.04.¶
On olemas (probleem)mis takistab Ubuntul näidata luks dekrüpteerimise ekraani, kui see käivitatakse peaga. Tema on seal ja sa võid sisestada oma parooli pimesi, pärast seda Ubuntu käivitub normaalselt. Järgige neid samme:
Pead alustavad. Kui midagi ei ole vaja teha, käivitub Ubuntu automaatselt
Mõne aja pärast näete musta ekraani, mille viimased read on valged:
Locking TPM2 platform hierarchy...
Starting the new kernel
Need read näitavad, et Ubuntu käivitub.
Oodake 5 sekundit ja seejärel sisestage oma salasõna („12345678“, kui käivitate selle esimest korda), millele järgneb Sisestage.
Nüüd näete tavalist Ubuntu ekraani. Esmakordsel käivitamisel peate lõpetama algkonfiguratsiooni.
Alustamine¶
Pärast ostu sooritamist on paroolid määratud vaikimisi ja neid peate ise muutma:
Vajutage Enter („Default Boot“) pärast süsteemi käivitamist, kui NitroPad ei ole näidanud ühtegi viga ja Nitrokey põleb roheliselt (vt eespool).
Seejärel palub süsteem sisestada kõvaketta dekrüpteerimiseks salasõna. Salasõna on esialgu „12345678“. Seda muudeti 10.04.2024, nii et kui „12345678“ ei tööta, proovige vana vaikimisi: „PleaseChangeMe“.
Seejärel juhatab süsteem teid läbi kasutajakonto loomise protsessi. Pärast seda peaksite süsteemi edukalt käivitama ja seda juba normaalselt kasutama.
Open the pre-installed Nitrokey App and change the PINs of your Nitrokey. To learn more about how to change the PINs, please refer to chapter Change User and Admin PIN.
Muutke kettakrüpteerimise salasõna. Lisateavet selle kohta, kuidas muuta ketta krüpteerimise salasõna, leiate peatükist Ketta krüpteerimise salasõna muutmine. See parool erineb teie kasutajakonto paroolist’see parool on erinev.
Käitumine pärast süsteemi uuendamist¶
The NitroPad and NitroPC firmware checks certain system files for changes. If your operating system has updated important components, you will be warned the next time you boot the NitroPad or NitroPC. This could look like this, for example:

That’s why it’s important to restart your NitroPad or your NitroPC under controlled conditions after a system update. Only when the new status has been confirmed can you leave the device unattended again. Otherwise, you will not be able to distinguish a possible attack from a system update. Detailed instructions for a system update can be found here.
