更新到 groovy 之后，内核在某个时候更新了，现在我必须启动到 5.8.0-25-generic 才能使用我的无线。以下是两者上 lshw -C network 的输出。这是最新内核中缺少正确固件的错误吗？还是以某种方式无法使用最新固件声明接口？过去一个月似乎在 linux-firmware 软件包上做了一些工作https://git.kernel.org/pub/scm/linux...962e5c7316924b 我不能确定这是否是问题所在尽管。还有什么可以做或检查的吗？
固件似乎存在

更新：我实际上注意到在 5.8.0-26-generic 中没有加载很多内核模块。也许这不是驱动程序/固件的问题。

由于
5.8.0-26某种原因没有完全安装。跑
安装内核的其余部分。
发生这种情况是因为
linux-generic缺少元包。它脉冲所有必要的内核包。安装它否则您将无法获得内核更新。
