Installation Steps

Follow these steps to install Proton Mail Bridge on your Chromebook:

  1. Update your package list:
    sudo apt update
  2. Install Flatpak, which is a utility for software deployment and package management:
    sudo apt install flatpak
  3. Add the Flathub repository, which hosts a large collection of Flatpak applications:
    sudo flatpak remote-add --if-not-exists flathub
  4. Install Proton Mail Bridge using Flatpak:
    sudo flatpak install flathub ch.protonmail.protonmail-bridge
  5. Set the correct permissions for the bwrap utility, which is used by Flatpak:
    sudo chown root:root /usr/bin/bwrap && sudo chmod u+s /usr/bin/bwrap

Additional Information

Proton Mail Bridge acts as an intermediary between your Proton Mail account and your local email client. It encrypts and decrypts your emails locally, ensuring that your messages remain secure and private throughout the entire process. This is particularly useful for users who prefer to use desktop email clients or need offline access to their emails.

When setting up Proton Mail Bridge, you'll need to configure your email client with the IMAP and SMTP settings provided by the Bridge application. This process may vary depending on your chosen email client, so be sure to consult the documentation for both Proton Mail Bridge and your email client for detailed setup instructions.

Troubleshooting Tips

  • If you encounter issues with the Flatpak installation, ensure that your Chromebook's Linux environment is up-to-date by running sudo apt update && sudo apt upgrade before attempting the installation again.
  • Some users may experience connectivity issues between their email client and Proton Mail Bridge. In such cases, check your firewall settings and ensure that the necessary ports are open for communication.
  • If you're having trouble with authentication, double-check that your password manager is correctly set up and accessible to Proton Mail Bridge.
