Ubuntu 22.04.2中RTL8821CE无线网卡更新后变为未认领状态的求助

大家好，我遇到个棘手的问题想求助：我妻子的电脑开启了Livepatch功能，今天系统更新之后，无线网卡突然变成了**未认领（UNCLAIMED）**状态，完全没法用WiFi了。我的系统是Ubuntu 22.04.2版本。

我首先执行了sudo lshw -C network命令查看网卡状态，得到的输出如下：

接着我用sudo dmesg | grep 8821命令查看相关日志，输出内容是：

我还尝试用dkms查看状态，但输入命令后出错了，执行的命令和错误信息如下：

sudo dkms --status

有没有朋友遇到过类似的问题？或者能给我一些排查和解决的建议吗？非常感谢！
