Zoom won't launch on Ubuntu 20.04

Yesterday I installed Zoom on my laptop and worked perfectly. Today, when I wanted to launch it again, it doesn't launch. I installed it using this command:

sudo apt install ./zoom_amd64.deb

and it was installed without errors. I tried reinstalling it and nothing. Here is a log file: https://drive.google.com/file/d/1Ri6oWeJJLdGPOVbWVQgCqOlFZaP4VmCM/view?usp=sharing

Can someone help?

UPDATE: I tried launching Zoom from terminal and it didn't work. However, when I switched to root and tried launching it again, Zoom launched but I can't do anything.

You can try uninstalling Zoom that was installed from the .deb package and install a snap one:

sudo snap install zoom-client

I found a possible solution to maybe not this problem, but after much research I need to share:

Step 1: Find missing packages, in terminal type: (I think you have to have tried to launch zoom from terminal to get this)

ldd /opt/zoom/libdvf.so | grep "not found"

This was my output:

        libxcb-icccm.so.4 => not found
        libxcb-render-util.so.0 => not found

Step 2: Install missing packages, in terminal:

In my case

sudo apt install libxcb-icccm4 libxcb-render-util0

Step 3: Profit (It works!)

Nothing happened when zoom was launched from the GUI, when run from the cli it showed the message Testing for explicit PulseAudio choice... ...and PulseAudio has been explicitly chosen Reinstalling the .deb package or using snap did not solve the problem.

Launched pulseaudio:

$ pulseaudio

There was a message in the pulseaudio log: main.c: An error occurred while executing pa_pid_file_create(), which led me to check the alsamixer utility.

Launched alsamixer

$ alsamixer

The alsamixer interface showed that everything was muted (MM). After alsamixer was reconfigured, zoom started.

I hope this solves someone's problem and saves a lot of time.

Open Software & Updates, go on Livepatch and if you enable it and get errors like Failed to read Machine ID or this machine ID is already enabled with a different key or is non-unique this is why zoom doesn't launch.

• For Failed to read Machine ID you can try the solution found here:

  sudo touch /etc/machine-id
  sudo systemd-machine-id-setup
  cat /etc/machine-id
  

• For this machine ID is already enabled with a different key or is non-unique check this question: Problem trying to use Livepatch

Hope this helps!
