 如果你访问 github.com 的网络不通畅，无法在线下载更新时，可以手动下载内核，上传至 Armbian 系统的任意目录，并进入内核目录，执行 `armbian-update` 进行本地安装。如果当前目录下有成套的内核文件，将使用当前目录的内核进行更新（更新需要的 4 个内核文件是 `header-xxx.tar.gz`, `boot-xxx.tar.gz`, `dtb-xxx.tar.gz`, `modules-xxx.tar.gz`。其他内核文件不需要，如果同时存在也不影响更新，系统可以准确识别需要的内核文件）。在设备支持的可选内核里可以自由更新，如从 5.10.125 内核更新为 5.15.50 内核。

 If the network where you access github.com is blocked and you cannot download updates online, you can manually download the kernel, upload it to any directory on the Armbian system, enter the kernel directory, and execute `armbian-update` for local installation. If there is a set of kernel files in the current directory, it will be updated with the kernel in the current directory (The 4 kernel files required for the update are `header-xxx.tar.gz`, `boot-xxx.tar.gz`, `dtb-xxx.tar.gz`, `modules-xxx.tar.gz`. Other kernel files are not required. If they exist at the same time, it will not affect the update. The system can accurately identify the required kernel files). The optional kernel supported by the device can be freely updated, such as from 5.10.125 kernel to 5.15.50 kernel.
