discord-autoupdate-secure 1.4.2

Makes your .deb Discord desktop icon update Discord securely.

discord-autoupdate-secure

discord-autoupdate-secure makes the Linux Discord client behave like a trusted, self-updating application: every launch verifies the transport, checksums the .deb, installs only if it matches Discord’s own digest, and then hands control back to the regular app. It also ships with a shortcut bootstrapper so the stock “Discord” icon routes through this hardened updater.

Quick start (recommended flow)

1. Install the CLI (isolated)
   Use pipx (preferred):

   pipx install discord-autoupdate-secure
   

   Or pip in user mode:

   pip install --user discord-autoupdate-secure
   

   Installing into system site-packages with sudo pip is discouraged.

2. Bootstrap the desktop shortcut (installs Discord if needed)

   discord-autoupdate-secure --bootstrap
   

   This installs Discord when missing and rewrites the launcher for the current user. Run once per user account; the pip install step does not touch desktop files.

3. Launch Discord normally
   Use your desktop’s Discord shortcut as usual. It now runs discord-autoupdate-secure first, which checks for updates, elevates when approved, installs if required, and finally launches Discord.

What the bootstrapper changes

Running --bootstrap drops a managed discord.desktop into ~/.local/share/applications:

• The tool clones the current Discord desktop entry when possible so icons, categories, translations, and Flatpak/Snap flags remain intact.
• Only the Exec= line is rewritten to point at discord-autoupdate-secure; any original command-line options are preserved.
• Existing user-level entries are backed up as discord.desktop.bak, .bak1, etc. so you can revert if needed.
• If Discord is not installed yet, the bootstrapper downloads and installs the latest .deb first so the icon and desktop metadata exist before rewriting the launcher.
• Menus that honor the FreeDesktop spec (GNOME, Xfce/Xubuntu, KDE Plasma, Cinnamon, Budgie, etc.) automatically pick up the change. Reopen your menu or log out/in if you don’t see the new entry immediately.
• Re-run discord-autoupdate-secure --bootstrap whenever you want to refresh or repair the shortcut.

Everyday commands

Command	Purpose
discord-autoupdate-secure	Check for updates, install if needed, then launch Discord.
discord-autoupdate-secure --update	Update Discord only; do not launch afterward.
discord-autoupdate-secure --check	Print installed vs. latest versions without installing.
discord-autoupdate-secure --bootstrap	(Re)install the managed desktop shortcut for the current user.

During an update the tool uses Tk to confirm you actually want to elevate. Redirects that leave Discord-owned domains or downloads that fail the MD5 digest published by Discord are rejected with an explanation.

Troubleshooting

• “Could not find Discord executable.” The CLI expects discord (or Discord) in your PATH. If you installed via Snap/Flatpak, ensure the binary is exposed or edit the desktop file to point to the wrapper you use.
• “Refusing untrusted download host.” Captive portals and filtering proxies sometimes rewrite the download URL. Retry on a trusted connection and make sure discord.com resolves correctly.
• Checksum mismatch / dpkg failure. The .deb may have changed mid-download or your package database is in a bad state. Run discord-autoupdate-secure --update from a terminal to see full logs, then inspect /var/log/apt/term.log.
• Desktop icon didn’t change. Run discord-autoupdate-secure --bootstrap again, then refresh your desktop database via update-desktop-database ~/.local/share/applications or log out/in.
