Can't install latest Zoom version

I had the same issues, in Ubuntu 20.04. This is what worked for me:

Using the terminal

  1. Download the DEB installer file from our Download Center
  2. Open the download location using a file manager.
  3. Right click in the file manager and click Terminal or Open in Terminal to open the terminal in the current location.
  4. Type in the following command and press Enter to run it.

sudo apt install ./zoom_amd64.deb
