在为我的 wifi 适配器安装反向移植时，我的终端出现以下错误。
我的 askubuntu 问题是我的 Qualcomm Atheros QCA9377 无线适配器无法在 Ubuntu 20.04 LTS 中使用（供应商：联想型号：E41-25）
我使用的内核版本：
wintersoldier@wintersoldier:~$ uname -s -r
Linux 5.8.12-050812-generic
我的错误是：
wintersoldier@wintersoldier:~$ cd backports-20151120
wintersoldier@wintersoldier:~/backports-20151120$ make defconfig-wifi

请帮我解决我的问题
答案1
您无法在内核源代码树中创建目录，因为其中的文件/usr/src都归超级用户 ( root) 所有。
我尝试对脚本进行以下修改你的其它问题：
tar zxvf backports-20151120.tar.gz # like original
cd backports-20151120 # like original
sudo rsync -axvH /usr/src/linux-headers-`uname -r` /usr/src/linux-headers-`uname -r`.backup # make a backup copy first
sudo chown -vR $USER /usr/src/linux-headers-`uname -r` # change ownership of all kernel headers
make defconfig-wifi # resume script
现在，这仍然失败，Generating local configuration database from kernel ...Kernel version parse failed!但没有cannot create directory错误。
您尝试安装的反向移植如下这个脚本它是在 2016 年创建的；你确定需要构建内核吗？（我的库存安装有 QCA9377 的固件）：
ls -lR /lib/firmware/ath10k/QCA9377/
