I’m trying to install it on Debian Linux, local (not cloud) environment.

Installing Stalwart on Debian Linux is straightforward using the official one-liner installer. Here is the full process:

1. Download and run the installer (as root):

curl --proto '=https' --tlsv1.2 -sSf https://get.stalw.art/install.sh -o install.sh
sudo sh install.sh

The script automatically detects systemd (standard on Debian), creates a stalwart service account, places files in standard FHS paths (/usr/local/bin/, /etc/stalwart/, /var/lib/stalwart/, /var/log/stalwart/), and starts the service immediately.

2. Retrieve the temporary admin password:

sudo journalctl -u stalwart -n 200 | grep -A8 'bootstrap mode'

This shows a one-time temporary admin password printed at first startup.

3. Open the setup wizard:
Navigate to http://127.0.0.1:8080/admin in a browser (on the local machine), sign in with admin and the temporary password, and follow the 5-step wizard. For a local/internal deployment the key choices are:

  • Step 1: Set your server hostname and domain (.local or .test TLDs work fine for non-public setups).
  • Step 2: Storage defaults (RocksDB on disk) are fine for a single-node install - no changes needed.
  • Step 3: Leave set to Internal Directory for simplest setup.
  • Step 5: Leave DNS management as Manual for a local environment.

4. Restart the service after completing the wizard:

sudo systemctl restart stalwart

Full details are in the Linux installation guide.

This I did. After that no password is working.

There are two passwords in play: When the installer runs it prints a one-time bootstrap admin password to the service log, which you use to reach the setup wizard at http://:8080/admin. The wizard then sets a permanent admin password and shows it once on the final screen. If you missed the bootstrap one, you can find it with:

sudo journalctl -u stalwart -n 200 | grep -A8 ‘bootstrap’
