Option 1: official binary
Download the tar.xz archive, extract it and run the Telegram executable. It does not depend on system library versions and works on any distro; you can move the folder to /opt and create a launcher.
Option 2: Flatpak
Run flatpak install flathub org.telegram.desktop. Sandboxing keeps things tidy and Flathub handles updates.
Option 3: Snap
Run sudo snap install telegram-desktop — handy on Ubuntu and others with Snap preinstalled, with automatic background updates.
Which to pick
- Latest version: the official binary;
- Clean isolation: Flatpak;
- Zero effort: Snap or your distro repository.
