Install or update Zoom on Linux

Overview

This article explains how Linux users can install or update the Zoom desktop app and, when needed, import Zoom’s public signing key to validate the installation package.

Who this applies to

• Linux users installing Zoom for the first time
• Linux users updating an existing Zoom desktop app installation
• Linux users or administrators who need to validate Zoom installation packages before installing them

Before you begin

If you are installing Zoom on Linux for the first time, follow Zoom’s instructions to install or update Zoom on Linux.

If you already use Zoom on Linux, you may need to import Zoom’s current public signing key before updating the Zoom desktop app. This is especially important if your Linux distribution or local security process checks package signatures before allowing software to install.

Why the GPG validation key is needed

Zoom signs its Linux installation packages with a cryptographic key. Linux can use Zoom’s public signing key to confirm that the package came from Zoom and has not been changed since Zoom signed it.

When Zoom changes or retires a signing key, some Linux systems may block an update or display a signature validation warning until the new public key is imported. Importing the current key helps the system verify the Zoom package before installation.

Instructions

1. Download package-signing-key.pub from Zoom’s public key download link.
2. Open a terminal.
3. Run the command for the type of Zoom package you are installing or validating.

• For Debian, Ubuntu, or Linux Mint packages:
  Import the public key:
  gpg --import ~/Downloads/package-signing-key.pub
  Install the validation tool and verify the Zoom package:
  sudo apt install dpkg-sig && dpkg-sig --verify ~/Downloads/zoom_amd64.deb

• For Red Hat, CentOS, Oracle Linux, Fedora, or other RPM-based packages:
  Import the public key:
  sudo rpm --import ~/Downloads/package-signing-key.pub
  Verify the Zoom package:
  rpm -K ~/Downloads/zoom_x86_64.rpm

Expected result

If the package validates successfully, the command should report a good or valid signature. You can then continue with the Zoom installation or update.

Troubleshooting tips

• The key file cannot be found: Confirm that package-signing-key.pub is in your Downloads folder. If it was saved somewhere else, update the command with the correct file path.
• The package file name is different: The commands in this article use common Zoom package names. If your downloaded file has a different name, replace zoom_amd64.deb or zoom_x86_64.rpm with the exact file name in your Downloads folder.
• The command says dpkg-sig is not installed: Run the Debian, Ubuntu, or Linux Mint command again and enter your password when prompted. The command installs dpkg-sig before validating the package.
• The signature still fails after importing the key: Download the current public key again directly from Zoom’s Download Center, then repeat the import and validation steps.
• You are using Fedora or another RPM-based distribution and see a GPG signature or key error: Make sure you imported Zoom’s current public key and that the package file is the current version from Zoom. If the error continues, check whether your Linux distribution has a known issue with third-party package signature validation.
• You are unsure whether a Zoom email or key notice is legitimate: Do not use links from suspicious emails. Go directly to Zoom’s Download Center or Zoom’s support article and download the key from there.

Need help?

If you are unable to install or update Zoom after importing the public key, contact the IT Support Center for assistance. Include your Linux distribution, the Zoom package file name, and any error message you received.
