How to Install Schleuder on Void Linux

Schleuder is an open-source email list manager that provides end-to-end encryption and supports various authentication methods. This tutorial will guide you through the installation of Schleuder on Void Linux.

Prerequisites

• A server running Void Linux
• A non-root user with sudo privileges
• Basic knowledge of the command line interface

Step 1: Update the System

Before installing any packages, it's recommended to update the system’s repository and package list.

You can do this by running the following command:

sudo xbps-install -Suy

Step 2: Install the Required Dependencies

Schleuder depends on several packages that need to be installed in advance. You can install them by running the following command:

sudo xbps-install -y gnupg ruby ruby-devel sqlite sqlite-devel libsodium-devel libsodium

Step 3: Install Schleuder

Once you have installed all the required dependencies, you can proceed with the installation of Schleuder itself. To do this, you can run the command:

sudo gem install schleuder

This command will install the latest version of Schleuder.

Step 4: Create a User and a Directory for Schleuder

Schleuder needs a system user and a directory where it can store configuration files, keyrings, and mailing lists.

You can create a user by running the following command:

sudo useradd -r -m -d /var/lib/schleuder -s /bin/false schleuder

Next, create a directory for Schleuder:

sudo mkdir -p /var/lib/schleuder
sudo chown -R schleuder: /var/lib/schleuder

Step 5: Create and Configure the Schleuder Instance

After you have created a user and a directory for Schleuder, you need to create and configure a Schleuder instance. To do that, follow these steps:

1. Copy the sample configuration file to the /etc/schleuder directory:

sudo cp /usr/local/share/schleuder/config/schleuder.yml /etc/schleuder/schleuder.yml

2. Create a new GnuPG keyring for Schleuder:

sudo su -s /bin/bash -c "gpg --homedir /var/lib/schleuder/.gnupg/ --gen-key" schleuder

3. Export the key by running the following command:

sudo su -s /bin/bash -c "gpg --homedir /var/lib/schleuder/.gnupg/ --export-secret-key --armor" schleuder > /etc/schleuder/schleuder.gpg.asc

4. Import the key into the system-wide GnuPG keyring:

sudo su -s /bin/bash -c "gpg --import /var/lib/schleuder/.gnupg/secring.gpg" schleuder

5. Generate a random password for the mailing list's admin user:

tr -dc '[:alnum:]' < /dev/urandom | fold -w20 | head -n1 > /etc/schleuder/mailinglist-admin-passwd

6. Edit the /etc/schleuder/schleuder.yml configuration file with your desired settings:

sudo nano /etc/schleuder/schleuder.yml

In this file, you can set up your email server, the log file path, the mailing list configuration, and other options as per your requirements.

Step 6: Enable and Start Schleuder Service

Now that you have completed the installation and configuration of Schleuder, the next step is to enable and start the service.

sudo ln -s /etc/sv/schleuder /var/service/
sudo sv up schleuder
sudo sv status schleuder
