ubuntu-post-install

Modular post-install system for Ubuntu servers. One repo, one entry point, install only what you need — interactively or by name.

Quick start on a fresh box

Public repo — paste on any new box:

curl -fsSL https://raw.githubusercontent.com/outis1one/ubuntu-post-install/main/bootstrap.sh | sudo bash

USB thumb drive — works for public or private repos:

Prepare the USB once on any machine (no git required):

1. Go to the repo on GitHub → green Code button → Download ZIP
2. Unzip it — you'll get a folder called ubuntu-post-install-main
3. Copy that folder to your USB drive

On every new box:

1. Plug in the USB — it opens in the file manager
2. Navigate into the ubuntu-post-install-main folder
3. Either:
   • Right-click inside the folder → Open in Terminal → type bash bootstrap.sh
   • Or double-click bootstrap.sh → if prompted, choose Run in Terminal

The script asks for your password if needed. It detects it is running from inside the repo, copies everything to ~/ubuntu-post-install, then launches the wizard — the USB can be unplugged once setup starts.

Private repo — PAT (alternative):

sudo bash bootstrap.sh --pat ghp_xxxxxxxxxxxxxxxxxxxx

Use a fine-grained read-only PAT scoped to just this repo (Contents: Read). The PAT is stripped from the stored remote URL after cloning.

Usage

sudo ./setup.sh                        # interactive wizard
sudo ./setup.sh caddy immich           # install specific services
sudo ./setup.sh configure              # set site defaults (timezone, domain, Caddy network)
./setup.sh --list                      # list all services grouped by category
sudo ./setup.sh --dry-run immich       # preview without making changes
sudo ./setup.sh --unattended base      # non-interactive, use defaults

What the wizard does

First run:

1. Installs essential CLI packages (net-tools, ncdu, git, curl, wget, htop, tree, zip/unzip, ca-certificates, gnupg, jq, rsync, glow), Docker CE + Compose plugin, and openssh-server — offers to import SSH keys from GitHub/Launchpad (ssh-import-id), disable password login once a key is confirmed, install NetBird, and add SSH Host aliases (see SSH Host aliases)
2. Asks where Caddy runs — this machine, a remote machine/VPN peer, or none — before anything else, since every later service prompt depends on the answer
3. If Caddy is local: offers to set site defaults — timezone, base domain, Caddy Docker network — so every service picks them up automatically instead of asking each time, then offers to install Caddy itself
4. Drops into a category menu — pick a group, tick services, install, repeat
5. Ends by dropping you into a fresh login shell so the docker group takes effect immediately (no manual newgrp docker or SSH reconnect needed)

Re-run: skips steps already completed, shows a summary of installed services, and goes straight to the menu.

Site defaults are saved to ~/docker/.config and pre-fill every service prompt. Update them any time with sudo ./setup.sh configure. Remote/none Caddy mode skips the domain/timezone prompt entirely — service installers instead save a ready-to-copy Caddy config snippet to ~/docker/caddy-snippets/.

Services

Group	Services
base	net-tools, ncdu, git, curl, wget, htop, tree, zip/unzip, ca-certificates, gnupg, jq, rsync; glow (terminal markdown reader, Charm apt repo); Docker CE + Compose plugin; openssh-server with GitHub/Launchpad SSH key import, optional password-auth lockdown, and SSH Host aliases; optional NetBird overlay network
homelab	caddy, crowdsec, authelia, coturn (shared TURN/STUN relay — Asterisk, Mattermost Calls, and future WebRTC-capable services all register a dedicated credential against one instance instead of each running its own), homeassistant, asterisk, pstn-trunk, sms-inbound, security-dashboard, sunshine
utilities	actualbudget, ai-gpu, ai-stack, archivebox, changedetection, ddclient, filebrowser, fmd, gatus, homebox, iopaint, joplin, koha, magicmirror, mail-archiver, mattermost, mealie, meshcentral, n8n, nextcloud, ntfy, onlyoffice, paintplus, portainer, rustdesk, stirling-pdf, syncthing, traccar, unifi, uptimekuma, vaultwarden, watchyourlan, watchtower, wg-easy
media	arm, audiobookshelf, calibre-web, emby, immich, jellyfin, lyrion
cameras	frigate, frigate-audio, frigate-notify, sky-cam
gaming	drum-rhythm-game, js99er, kyber-launcher, kyber-server, minecraft, wolf, wolf-pair
extras	kdeconnect, silent-send, ssh-config, sync-cc
backup	backup — complete recovery: entire ~/docker/<service>/ for every service via Kopia (Minecraft: flush+snap, no downtime; others: stop/snap/start for DB consistency), optional offsite mirror (kopia repository sync-to), plus dr_bringup.sh — unattended restore-everything-and-start for standing up a cold spare box; borg-backup — same coverage via Borg (chunk dedup, SSH remote repos, Borgmatic/Vorta compatible); gaming-backup — frequent game-save snapshots (Minecraft world data, emulator saves, Steam — no downtime, run hourly)

Run ./setup.sh --list to see descriptions.

Layout

lib/common.sh     shared helpers: logging, prompts, site config, OS detection
services/         one file per service (self-registering)
vendor/           full app source trees vendored for a service (e.g. ai-stack,
                  paintplus, easy-asterisk) — copied into place at install time,
                  no network clone needed
extras/           non-Docker assets bundled with the repo (e.g. sync_cc.py)

Managing installed services

Every Docker service installs to its own ~/docker/<name>/ folder:

cd ~/docker/immich
docker compose up -d        # start
docker compose logs -f      # logs
docker compose pull && docker compose up -d   # update
docker compose down         # stop

SSH Host aliases

~/.ssh/config lets you ssh <alias> instead of typing ssh user@1.2.3.4 every time — especially handy once machines are reachable over a VPN/NetBird overlay network where the IP is easy to forget:

Host myserver
    HostName 100.x.x.x
    User someuser
    Port 22

Three ways to manage these entries:

• During base install — after SSH key import, the wizard offers to add one or more aliases interactively
• Any time — sudo ./setup.sh ssh-config lists, adds, or removes aliases without touching anything else
• By hand — edit ~/.ssh/config directly; it's a plain OpenSSH client config file, nothing generated or templated beyond the Host block itself

Aliases are written to the invoking user's own config (not root's), since that's whose terminal actually runs ssh.

Installing from a USB thumb drive

No git required. Works for anyone with a browser.

1 — Put the repo on the USB

1. On GitHub: click Code → Download ZIP
2. Open your Downloads folder — right-click the ZIP → Extract Here
3. Drag the ubuntu-post-install-main folder onto the USB drive in the file manager sidebar

To update later: download the ZIP again, extract, drag the new folder to the USB and replace the old one.

2 — Run on the target machine

Plug in the USB. Open the ubuntu-post-install-main folder in the file manager, then either:

• Right-click inside the folder → Open in Terminal, then run:

  sudo bash bootstrap.sh
  

• Double-click bootstrap.sh → click Run in Terminal → it prompts for your sudo password and starts the wizard automatically.

Notes

• Everything the wizard installs goes to ~/docker/ on the target machine's disk — only the setup scripts live on the USB.
• exFAT is the best filesystem for the USB — readable on Windows and macOS for easy ZIP extraction, and works fine on Linux.

Compatibility

Tested on Ubuntu 24.04 LTS and 26.04 LTS. Works on any Ubuntu LTS ≥ 22.04; non-LTS releases also work. The wizard shows the detected OS in the header and warns on unknown versions.

Gaming scripts

Gaming setup walkthroughs live next to their service files, not here — see services/<name>.md (e.g. services/kyber-launcher.md for SWBF2 (2017) + Kyber: playing, hosting, and troubleshooting). It's appended automatically to ~/.local/share/kyber/README.md when you run sudo ./setup.sh kyber-launcher.

Also in scripts/ (standalone, not part of the main wizard): setup-swbf2-linux.sh (native Steam/Proton fixes for the base game), setup-kyber-linux.sh (standalone equivalent of the kyber-launcher service), and Wolf/Games-on-Whales container variants (setup-swbf2-wolf.sh, setup-kyber-wolf.sh).
