Error with cups-daemon package when reinstalling many packages to recover wireless connection with QCA9377

[Leonardo Müller]

I had a issue with my Wireless and Bluetooth card, Qualcomm Atheros Device [168c:0042] (rev 30), which appears on Windows 10 as QCA9377, and to solve it I have searched and tried different alternatives. The one that worked was to reinstall many packages, all the ones I have found when searching for, firstly, "wireless", then "wifi" and then "internet", on synaptic. When doing the "internet" reinstall, a error happened on cups-daemon and it crashed. When I tried again, it worked. I rebooted the computer and the Wireless is functioning again (Bluetooth was already OK).

I am using the Kernel 4.9.10-040910-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9.10/ because I was trying to solve this issue and because the official Kernles 4.4 and 4.8 don't eject external HDDs from the USB 3.0 correctly. The notebook model is Lenovo Ideapad 310-14ISK.

While this window to report the bug appeared saying cups is the culprit, all this only happened because the wireless device QCA9377 was not working.

I hope this information may be helpful.
