我正在尝试将我的联想 X1 Carbon Gen 7 笔记本电脑设置为与 Ubuntu 19.10 双启动。尽管花了几个小时搜索并尝试了本网站和其他网站的解决方案，但我还是无法连接无线互联网。
这是我到目前为止尝试过的，命令是不按顺序的，因为经过这么多小时后我的大脑已经疲惫不堪，我真的记不清我所做的一切。
- Ubuntu 19.10 与 Windows 10 Pro 双启动
- 联想 X1 Carbon Gen 7
- 英特尔 AC-9560
快速启动和安全启动已禁用

通过检查此处确保 /lib/firmware 中拥有正确的驱动程序： https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi
重命名了除 -34 之外的所有 9000 系列驱动程序，因为这适用于另一位发帖者。例如：
sudo mv iwlwifi-9000-pu-b0-jf-b0-38.ucode iwlwifi-9000-pu-b0-jf-b0-38.bak
- sudo apt install linux-oem-osp1
- sudo apt install linux-firmware
- sudo service fwupd start
- sudo fwupdmgr refresh
- sudo fwupdmgr update
- sudo apt-get dist-upgrade
答案1
升级到最新版本有效。
我运行了更新管理器-d获得版本 20.04。重启电脑后，我不需要做任何事情。
