bcmwl-kernel-source 在内核上损坏：5.8.0-34-generic

Don*_*ung 27 wireless kernel broadcom macbook-air drivers

类似于bcmwl-kernel-source 在内核上损坏：5.8.0-7630-generic，但我使用的是标准内核 - WiFi 在我的 MacBook Air（2013）上没有问题，直到我拉入最新的 20.04.2 更新包含5.8.0-34-generic内核，5.4.0-59-generic之后重新启动并不能解决问题。总之，详情如下；任何帮助将非常感激。

我为尝试解决问题而采取的步骤

我按照安装 Broadcom 无线驱动程序并执行以下操作：

  1. lspci -nn -d 14e4: 显示 PCI.ID 是 14e4:43a0 (rev 03) 所以我应该（重新）安装 bcmwl-kernel-source
  2. sudo apt purge -y bcmwl-kernel-source
  3. sudo apt autoremove
  4. sudo apt update
  5. sudo update-pciids
  6. sudo apt-get install -y bcmwl-kernel-source

...然后重新启动。

我使用5.8.0-34-generic和5.4.0-59-generic内核完成了所有步骤（第一个步骤除外），最后一个命令的输出如下：

5.8.0-34-generic

与此同时，我的蓝牙正在工作，所以我通过蓝牙与我的 Android 设备共享连接到互联网。但这在很大程度上是一个临时解决方案，我不想长期依赖它。

原因很明显。几乎每次 Canonical 推出 HWE 内核时，他们都会忘记在存储库中升级bcmwl-kernel-source。

您有两种解决方案（使用一种或另一种，同时使用两者都没有意义）：

  1. bcmwl-kernel-source从groovyrepos安装。你可以在这里找到它。http://mirrors.kernel.org/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu7_amd64.deb它将使用 5.8 内核编译。

下载 deb 并通过以下方式安装它

sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu7_amd64.deb
Run Code Online (Sandbox Code Playgroud)

  1. 使用以下命令删除所有 5.8 内核包：

     sudo apt remove linux-{image,modules,modules-extra,headers}-5.8.0-36-generic linux-hwe-5.8-headers-5.8.0-36
 sudo apt install linux-generic
    Run Code Online (Sandbox Code Playgroud)

确保linux-generic安装了元包。

建议在删除 5.8 之前使用 5.4 内核引导。

第二种解决方案将保留 5.4 主要内核版本，并进行正常的安全升级。

  • 我认为添加 hwe 元也是某人的错误。在 xx.04.2 发布之前，它们从未出现过。这会给很多人带来麻烦。但是我使用 Ubuntu 已经很长时间了，并且希望在奇数年的每个年初都会出现一些混乱；-) (3认同)
