今天我刚开始使用 Ubuntu 18.04，除了使用 Asus PCE-AC68 802.11ac Wifi 卡的互联网连接外，一切都运行正常。在 Ubuntu 设置中，它显示“未找到 Wi-Fi 适配器”。我尝试了许多不同的指南和教程，但似乎都没有用。这是我下载驱动程序的尝试。
首先，我运行lspci -nn并收到以下结果，这是我的 Wifi 卡
05:00.0 Network controller [0280]: Broadcom Limited BCM4360 802.11ac
Wireless Network Adapter [14e4:43a0] (rev 03)
bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4_amd64.deb其次，我从 Ubuntu 18.04 安装 USB (usb/pool/restricted/p/bcmwl)获取文件，然后将其放在我的桌面上。然后我将dkms文件夹从 (usb/pool/main/d)移出
sudo dpkg -i *.deb
我收到了这个输出

处理时遇到错误：bcmwl-kernel-source dkms
最后我运行sudo modprobe wl并收到以下内容：

如果有人知道我哪里错了或者有其他解决方案，请告诉我

这是一个类似的帖子：离线 Broadcom 安装的依赖项未得到满足
正如@dadexi86 提到的，如果您有有线连接，可以（暂时）用来下载这些依赖项，那就更好了。如果没有，您必须从 Launchpad 等地方逐个下载它们（例如https://launchpad.net/ubuntu/bionic/+package/g++) 然后以某种方式将它们传输到您的机器。之后您可以运行以下命令（大致按正确顺序）：
sudo dpkg -i linux-libc-dev_4.15.0-20.21_amd64.deb sudo dpkg -i libc-dev-bin_2.27-3ubuntu1_amd64.deb sudo dpkg -i libc6-dev_2.27-3ubuntu1_amd64.deb sudo dpkg -i libitm1_8-20180414-1ubuntu2_amd64.deb sudo dpkg -i libatomic1_8-20180414-1ubuntu2_amd64.deb sudo dpkg -i libasan4_7.3.0-16ubuntu3_amd64.deb sudo dpkg -i liblsan0_8-20180414-1ubuntu2_amd64.deb sudo dpkg -i libtsan0_8-20180414-1ubuntu2_amd64.deb sudo dpkg -i libubsan0_7.3.0-16ubuntu3_amd64.deb sudo dpkg -i libcilkrts5_7.3.0-16ubuntu3_amd64.deb sudo dpkg -i libmpx2_8-20180414-1ubuntu2_amd64.deb sudo dpkg -i libquadmath0_8-20180414-1ubuntu2_amd64.deb sudo dpkg -i libgcc-7-dev_7.3.0-16ubuntu3_amd64.deb sudo dpkg -i gcc-7_7.3.0-16ubuntu3_amd64.deb sudo dpkg -i gcc_7.3.0-3ubuntu2_amd64.deb sudo dpkg -i make_4.1-9.1ubuntu1_amd64.deb sudo dpkg -i dpkg-dev_1.19.0.5ubuntu2_all.deb sudo dpkg -i libstdc++-7-dev_7.3.0-16ubuntu3_amd64.deb sudo dpkg -i g++-7_7.3.0-16ubuntu3_amd64.deb sudo dpkg -i g++_7.3.0-3ubuntu2_amd64.deb sudo dpkg -i build-essential_12.4ubuntu1_amd64.deb sudo dpkg -i dkms_2.3-3ubuntu9_all.deb sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu4_amd64.deb
