3A NFC / Critical error: No Nitrokey 3 bootloader device found

Hi all,

I faced an issue while updating 3A NFC

OS: Qubes os 
Vm : debian 11
nitrokey 0.4.32
python 3.9
current firmware : v1.2.2

I used the same os to upgrade to the current firmware version

nitropy nk3 update
Command line tool to interact with Nitrokey devices 0.4.32
Do you want to download the firmware version v1.3.1? [Y/n]: y
Current firmware version:  v1.2.2
Updated firmware version:  v1.3.1

Please do not remove the Nitrokey 3 or insert any other Nitrokey 3 devices during the update. Doing so may damage the Nitrokey 3.
Do you want to perform the firmware update now? [y/N]: y
Please press the touch button to reboot the device into bootloader mode ...

It looks like you are missing the Nitrokey udev rules. See this guide for more information: Setting up The udev Rules For nitropy - Nitrokey Documentation

Resolved.
