我也按照评论中的建议使用了 grep 命令,但没有输出:

~/rtl8821CU/rtl8821CU$ grep rtw /etc/modprobe.d/*

答案1

您使用与 5.19 Linux 内核不兼容的 DKMS 从某个地方安装了驱动程序。

Ubuntu 22.04 最近升级到 5.19 内核,但驱动程序无法构建。

您可以使用带有 grub 菜单的先前的内核进行启动,并且加密狗应该可以工作。

使其永久运行的选项是:

  1. 找到一个支持 5.19 内核的修补驱动程序,或者自己修补。请不要问如何修补它。如果你不知道,那么这个选项不适合你。该驱动程序应该可以在 Ubuntu 22.10 上运行,因为它使用相同的内核。所以搜索起来更容易。

  2. 将您的系统切换到非 HWE 内核。
