# NOTE: These instructions only work for 64-bit Debian-based

# Linux distributions such as Ubuntu, Mint etc.

# 1. Install our official public software signing key:

curl https://updates.signal.org/desktop/apt/keys.asc | gpg --dearmor > signal-desktop-keyring.gpg

cat signal-desktop-keyring.gpg | sudo tee /usr/share/keyrings/signal-desktop-keyring.gpg > /dev/null

# 2. Add our repository to your list of repositories:

curl -o signal-desktop.sources https://updates.signal.org/static/desktop/apt/signal-desktop.sources

cat signal-desktop.sources | sudo tee /etc/apt/sources.list.d/signal-desktop.sources > /dev/null

# 3. Update your package database and install Signal:

sudo apt update && sudo apt install signal-desktopLinux AppImage Install Instructions

# 1. Download AppImage:

curl -L -O https://updates.signal.org/desktop/signal-desktop.AppImage

# 2. Download our official public AppImage signing key:

curl -o signal-appimage.asc https://updates.signal.org/static/desktop/appimage.asc

gpg --import signal-appimage.asc

# 3. Download signature and verify AppImage:

curl -L -O https://updates.signal.org/desktop/signal-desktop.AppImage.gpg

gpg --verify signal-desktop.AppImage.gpg signal-desktop.AppImage

# The `gpg --verify` command will show the following output for a good signature:

# gpg: Signature made

# gpg: using RSA key 4B16B7232DFAA439AD791002EF9F501F13EED94C

# gpg: Good signature from "Signal Messenger, LLC "

# You will also see a warning about trusted signatures for that key. This is normal

# and expected unless you manually mark the key as ultimately trusted (e.g. using

# the `gpg --edit-key` command).

# 4. Mark the AppImage as runnable then run it:

chmod +x signal-desktop.AppImage

./signal-desktop.AppImage

# The AppImage auto updates which can be configured in settings.
