Ubuntu 18.04.3 LTS 更新破坏了无线适配器：Qualcomm Atheros QCA9377

我遇到了一个问题。我最近在 Dell Inspiron 17 3000 笔记本电脑上将 Ubuntu 分区（与 Win10 双启动）更新为 18.04.3 LTS。重新启动后，操作系统不再识别我的无线适配器。运行lspci | grep -i "Wireless\|WiFi"产生： 02:00.0 Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31) 运行dmesg | grep -i firmware产生：

[     0.135169] Spectre V2 : Enabling Restricted Speculation for firmware calls
[     0.208518] ACPI : [Firmware Bug]: BIOS _OSI(Linux) query ignored
... (psmouse and dmc normal messages, irrelevant to problem)
[     17.269597] ath10k_pci 0000:02:00.0: firmware ver WLAN.TF.2.1-00021-QCARMSWP-1 api 6 features wowlan,ignore-top crc32 42e41877

运行rfkill list all产生：

0: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

运行uname -a结果： Linux user-ubuntu 5.0.0-31-generic #33~18.04.1-Ubuntu SMP Tue Oct 1 10:20:39 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux 如果您需要更多信息，请告诉我；我还是个新手。（我实际上是用这个分区来教我 Ubuntu）谢谢！

编辑：用户 heynnema 告诉我尝试切换到 5.0.0-29 内核，这似乎解决了问题。当我切换回来时，问题没有再次出现。但是，我被要求生成新的输出：命令dkms status没有生成输出。

我也遇到过这种情况，使用的是 Dell Wireless WLAN 1530 Half MiniCard（安装时设置了专有驱动程序勾选标记）。更新后，它停止工作了。

使用 grub 启动选择旧内核 5.0.0-23 使其再次工作。
