The application can be downloaded from https://get.delta.chat. Here you'll find binary releases for all supported platforms. See below for platform specific instructions. If you run into any problems please consult the Troubleshooting section below.

Linux <a id="linux"></a>

Flatpak <a id="flatpak"></a>

The primary distribution-independed way to install is to use the flatpak build. This is maintained in it's own repository, however a pre-built binary can be downloaded and installed from flathub which also has a setup guide for many Linux platforms.

Arch Linux <a id="arch-linux"></a>

WARNING: Currently the AUR package compiles from latest master. This can be more recent as the latest release, introduce new features but also new bugs.

If you have a AUR helper like yay or paru installed, you can install it by running yay -S deltachat-desktop-git and following the instruction in your terminal.

Otherwise you can still do it manually:

$ cd deltachat-desktop

$ npm install

# Build the app (only needed on the first time or if the code was changed)
$ npm run build

# Start the application:
$ npm start

For development with local deltachat-core read the docs

Troubleshooting <a id="troubleshooting"></a>

This module builds on top of deltachat-core-rust, which in turn has external dependencies. The instructions below assume a Linux system (e.g. Ubuntu 18.10).

Read the error, maybe it already tells you what you need to do. If not feel free to file an issue in this github repo.

Make sure that your nodejs version is 20.0.0 or newer.

If you still get errors look at the instructions in UPDATE_CORE Readme to set things up or write an issue.

Configuration and Databases <a id="config-and-db"></a>

The configuration files and database are stored at application-config's default file paths.
