Debian/Ubuntu APT Setup

1) Prerequisites​

  • Debian/Ubuntu with apt (HTTPS supported by default).

  • curl and gpg installed:

    sudo apt-get update && sudo apt-get install -y curl gpg

2) Choose a channel (Release vs Snapshot)​

Option A --- Release (recommended)​

Create the source list and import the signing key:

echo 'deb [arch=all] https://repository.mapsmessaging.io/repository/maps_apt_release/ stable main' | sudo tee /etc/apt/sources.list.d/mapsmessaging-release.list

sudo curl -fsSL https://repository.mapsmessaging.io/repository/public_key/daily/apt_daily_key.gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/mapsmessaging-apt.gpg

sudo apt-get update

Option B --- Snapshot (daily builds)​

Create the source list and reuse the same signing key:

echo 'deb [arch=all] https://repository.mapsmessaging.io/repository/maps_apt_daily/ development main' | sudo tee /etc/apt/sources.list.d/mapsmessaging-daily.list

# Key is already installed (mapsmessaging-apt.gpg)
sudo apt-get update

3) (Optional) Add both channels with pinning (prefer Release)​

If you want Release by default but keep Snapshot available for explicit installs/upgrades:

# Add BOTH lists (key already installed), then set pinning:
sudo tee /etc/apt/preferences.d/mapsmessaging <<'EOF'
Package: maps
Pin: release o=mapsmessaging-release
Pin-Priority: 900

Package: maps-ml
Pin: release o=mapsmessaging-release
Pin-Priority: 900

Package: *
Pin: release o=mapsmessaging-daily
Pin-Priority: 400
EOF

Notes:\

  • o= (Origin) is derived from repo metadata; if apt doesn't match, use apt-cache policy to see the exact o= value and adjust.\
  • With these priorities, Release is preferred; Snapshot can still be installed explicitly (see below).

4) Install Maps Messaging​

Standard edition:

sudo apt-get update
sudo apt-get install maps

ML-enabled edition:

sudo apt-get update
sudo apt-get install maps-ml

If both channels are configured and you need Snapshot specifically:

sudo apt-get install -t development maps
# or
sudo apt-get install -t development maps-ml

5) Service management (systemd)​

# Standard
sudo systemctl enable --now maps

# ML
sudo systemctl enable --now maps-ml

# Check status/logs
systemctl status maps
journalctl -u maps -n 200 --no-pager

6) Upgrades​

  • Regular upgrades (per your channel/pinning):

    sudo apt-get update
    sudo apt-get upgrade

  • Force upgrade from Release to Snapshot (one-off):

    sudo apt-get install -t development maps

7) Switching channels later​

  • Release → Snapshot: add snapshot list, then apt-get update and install with -t development.

  • Snapshot → Release: remove snapshot list (or lower its priority), ensure release list exists, apt-get update, then:

    sudo apt-get install maps/stable
    # or maps-ml/stable (use the release pocket name shown by `apt-cache policy`)

8) Verify repository & package selection​

apt-cache policy maps
apt-cache policy maps-ml

This shows the versions, priorities, and which repo apt will choose.

9) Uninstall​

sudo systemctl disable --now maps || true
sudo systemctl disable --now maps-ml || true
sudo apt-get remove maps maps-ml
# Optional: purge config
sudo apt-get purge maps maps-ml

10) Troubleshooting​

  • GPG/Signature issues: re-import the correct key, confirm the .gpg file exists in /etc/apt/trusted.gpg.d/, then:

    sudo apt-get clean
    sudo apt-get update -o Acquire::https::Verify-Peer=true

  • Pinning doesn't apply: check exact origins/labels:

    apt-cache policy | sed -n '/maps_apt_/,+5p'

    Adjust o= in /etc/apt/preferences.d/mapsmessaging accordingly.

  • Behind a proxy: set Acquire::http::Proxy / Acquire::https::Proxy in /etc/apt/apt.conf.d/01proxy.

Packages​

  • maps: Maps Messaging Server (standard).
  • maps-ml: Maps Messaging Server with ML features included.
