Sound Mute button toggles without unmuting in Google Chrome on Ubuntu 18.04

I'm using Ubuntu 18.04 with the fvwm desktop environment. My sound is muted in Google Chrome. When I move the mouse pointer over the audio icon on the tab, "The sound on this tab is muted" is displayed. When I right-click on the tab, I can toggle between mute and unmute. This has no effect. In Firefox, the sound is not muted. When I use the Ubuntu desktop environment with chrome, the sound is not muted either. Can anyone advise how to fix that please?

dpkg does not work with the installation of termux ubuntu, returns tar errors and terminates the program with the error code 1

I tried installing Termux Ubuntu on ChromeOS without developer mode or root privileges, and was successful until then. I accessed an Ubuntu shell from termux, but dpkg returns this error for each package, rendering the system unusable. This is the output of "apt install nano"

root @ localhost: ~ # apt install nano

usb – My computer does not recognize my phone on Ubuntu or Windows

I own a LG-K430T and share the internet via USB tethering with my desktop PC. Or I have done it for a year without interruption until my PC no longer recognizes my phone, neither under Windows 7 nor under Ubuntu 18.04.2. It is not even possible to share files because there is no pop-up (neither in the phone nor in the PC), but the phone is charging. I thought it might be my worn USB cable, but if I use the same USB cable with my sister's Huawei I can swap files / internet. Besides, I have tried it with 3 different USB cables and different connections, and my phone is still not recognized. Then I tried it on Ubuntu and to my surprise it still is not recognized. So, I think it's safe to say the cable is not the problem nor the operating system. (I also rebooted both the phone and the PC.) Then I tried to enable USB debugging in Ubuntu, followed by lsusb and nothing. My phone was last updated in April 2019 and the Android version is 6.0, so I have no idea what's causing the problem, even though I blame the phone.

On Windows, I tried to update the drivers of the Unknown Device in Device Management, but they are already up to date

Networking – WiFi does not detect networks Ubuntu 18.04 Macbook pro mid-2010

Sorry, if I'm not the right channel to post this. But I am in exactly the same situation. I have Ubuntu 18.04.03 LTS installed on a Macbook Pro in mid-2010 (Broadcom 4322 (14e4:433b)(rev 01), I could not configure the WLAN however. I've done all the steps suggested here, but I can not detect a Wi-Fi network. I followed this MacBook and can not find WiFi for Ubuntu 18.04 without success.

* NOTE: I'm new to Ubuntu, in fact this is an old MacBook Pro from my wife I'm trying to give a more useful life. I am connected via an ethernet cable. *

The issue I receive is:

Please help !!! and let me know if I need to open a new question or what policies apply. Thanks in advance.

EDIT: I'm not sure if this helps, but:

Ubuntu: FireFox: Strange Certificates – Ask Ubuntu

Just a quick question, hope that's in the right place.

I just installed Ubuntu 18.04 LTS and found two weird certificates in Mozilla FireFox 70.0.1 (64-bit) that were ringing a bell for some reason. Can someone confirm whether these two certificates should be present during a new installation?
