v4l2loopback无法在AWS ubuntu 18.04上加载模块 [英] v4l2loopback cannot load module on aws ubuntu 18.04

问题描述

当前试图将v4l2loopback安装到aws的ubuntu 18.04实例中并面对当前情况

Currently trying to install v4l2loopback into a ubuntu 18.04 instance at aws and facing the current situation

运行后(源安装也是如此)

After running (the same happens from source install)

sudo apt-get install linux-generic (tempts to load videodev)
sudo apt-get install v4l2loopback-dkms
sudo modprobe v4l2loopback

我遇到以下错误:

modprobe: ERROR: could not insert 'v4l2loopback': Unknown symbol in module, or unknown parameter (see dmesg

加载 videodev ( sudo modprobe videodev )

是否有任何方法可以重新编译加载 v4l2 / videodev 模块的内核?还是在云实例上进行v4l2loopback的任何替代选择?

Is there any way to recompile the kernel loading the v4l2/videodev modules? Or any alternative for v4l2loopback on cloud instances?

推荐答案

我在Ubuntu 20.04 LTS中遇到了相同的错误，并通过禁用将模块锁定到内核的安全启动来进行修复.

I get the same error in my Ubuntu 20.04 LTS and fix by disabling secure boot which lock modules loading into kernel.

sudo mokutil --disable-validation 

使用此命令需要新密码，然后重新启动系统.
在启动阶段，密码验证和启动到系统 modprobe 功能启动后，您需要选择更改安全启动阶段"部分的蓝色窗口.

Use this command which require new password, then reboot the system.
In the boot stage, a blue window appear where you need to choose the "change secure boot stage" section, after password validation and booting to system modprobe function should work.

如果系统中不存在 mokutil ，则可以从 apt-get 安装它们.

If mokutildoes not exist in your system you can install them from apt-get.
