WiFi驱动程序安装失败 – SSL错误：02001002：系统库：fopen：没有这样的文件或目录：bss_file.c：175
我刚刚在我的Aspire E 15（E5-573-35Q3）上安装了16.04
我有以下所示的Qualcom Atheros：
$ lspci -vvnn 03:00.0 Network controller [0280]: Qualcomm Atheros Device [168c:0042] (rev 30) Subsystem: Lite-On Communications Inc Device [11ad:0806] Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- SERR- <PERR- INTx- Latency: 0, Cache Line Size: 64 bytes Interrupt: pin A routed to IRQ 50 Region 0: Memory at b0400000 (64-bit, non-prefetchable) [size=2M] Capabilities: Kernel driver in use: ath10k_pci Kernel modules: ath10k_pci 要安装驱动程序，我按照以下方式操作，就像我之前使用的disros一样：
sudo apt-get install build-essential linux-headers-$(uname -r) git echo "options ath10k_core skip_otp=y" | sudo tee /etc/modprobe.d/ath10k_core.conf wget https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v4.4.2/backports-4.4.2-1.tar.gz tar -zxvf backports-4.4.2-1.tar.gz cd backports-4.4.2-1 make defconfig-wifi make sudo make install
除了“make install”之外，所有都运行良好。 我收到如下消息：
INSTALL /home/cecil/backports-4.4.2-1/compat/compat.ko At main.c:222: - SSL error:02001002:system library:fopen:No such file or directory: bss_file.c:175 - SSL error:2006D080:BIO routines:BIO_new_file:no such file: bss_file.c:178 sign-file: certs/signing_key.pem: No such file or directory
对于要安装的每个.ko重复（其中123个）
然后它说：
sign-file: certs/signing_key.pem: No such file or directory DEPMOD 4.4.0-21-generic depmod will prefer updates/ over kernel/ -- OK! Note: You may or may not need to update your initramfs, you should if any of the modules installed are part of your initramfs. To add support for your distribution to do this automatically send a patch against "update-initramfs.sh". If your distribution does not require this send a patch with the '/usr/bin/lsb_release -i -s' ("Ubuntu") tag for your distribution to avoid this warning. Your backported driver modules should be installed now. Reboot.
然后我用以下方法获取固件：
git clone https://github.com/kvalo/ath10k-firmware.git sudo cp -r ath10k-firmware/QCA9377 /lib/firmware/ath10k/ sudo cp /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin_WLAN.TF.1.0-00267-1 /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin
这似乎运行正常，但当我重新启动 – 仍然没有检测到wifi。
这是新发行版中的错误，还是我必须做其他事情？
谢谢

我跑了dmesg |grep ath – 一无所获
我跑了lsmod |grep ath – 一无所获
我试着用sudo modprobe ath10k_pci
得到了消息：
modprobe: ERROR: could not insert 'ath10k_pci': Required key not available
我尝试了modprobe -r ath10k_pci以防万一，但它没有找到它删除它。
好的 – 我通过尝试安装ath10k_pci驱动程序删除了我所做的混乱：
sudo make uninstall (in the backports.... directory)
然后我重新启动 – lsmod发现现在安装的驱动程序：
ath10k_pci 45056 0 ath10k_core 311296 1 ath10k_pci ath 32768 1 ath10k_core mac80211 737280 1 ath10k_core cfg80211 565248 3 ath,mac80211,ath10k_core
dmesg|grep ath发现了我需要的固件的大量信息。 你能翻译一下:-)

谢谢
AHA – 我认为这是固定的。
我看到发行版没有QCA9377驱动程序。
然后，我通过尝试编译自己的东西搞砸了大部分时间。 一旦解决了这个问题，那么通过将QCA9377驱动程序复制到/ lib / firmware …系统现在可以找到正确的驱动程序和Walllaaaa！
感谢chilli555 – 问题解决了！
加载驱动程序时出现此错误，显示make和sudo make install ：
sudo modprobe ath10k_pci modprobe: ERROR: could not insert 'ath10k_pci': Required key not available
让我们卸载你从backports构建的驱动程序。 它不是必需的，因为它已经存在于Ubuntu 16.04中：
cd ~/backports-4.4.2-1 sudo make uninstall
重新启动并检查是否加载了默认驱动程序：
lsmod | grep ath
如果是这样，消息日志应该向我们显示需要什么固件，如果不是您已安装的固件。 校验：
dmesg | grep ath
实际上，如果缺少固件，我将编辑此答案以解释如何安装它。
