Troubleshooting (Linux)

• 如果硝基钥匙没有立即被接受，你可能需要复制这个文件`41-nitrokey.rules <https://www.nitrokey.com/sites/default/files/41-nitrokey.rules>`__到``etc/udev/rules.d/`__。在非常罕见的情况下，系统将需要这个文件的`较旧版本<https://raw.githubusercontent.com/Nitrokey/libnitrokey/master/data/41-nitrokey_old.rules>`__。

• 复制文件后，通过``sudo service udev restart``重新启动udev。
