This project was born out of my need to work during frequent power outages in my country. So I needed a solution that could provide deb packages, npm packages, and file hosting all in one place while consuming minimal resources.

What is UI APT Mirror?

UI APT Mirror is a containerized solution that creates a complete offline development environment. It includes an APT mirror for Ubuntu/Debian packages, an optional npm proxy for Node.js packages, file hosting with media streaming, and developer cheatsheets - all accessible through web interfaces.

Key features

APT Mirror: Local Ubuntu/Debian package repository with automatic sync
NPM Proxy: Optional local npm registry cache for faster installs
File Hosting: Built-in file manager with video/audio streaming support
Admin Panel: Web interface for monitoring and management
Developer Cheatsheets: Offline command references and documentation
Multi-architecture: Supports both ARM64 and AMD64 systems

The setup script will ask for your domain (default: mirror.intra), sync frequency, admin password, and whether you need npm proxy functionality.

Using the mirror

Once deployed, you get multiple web interfaces:

http://mirror.intra - Browse and download packages
http://admin.mirror.intra - Admin panel for monitoring
http://files.mirror.intra - File hosting with media streaming
http://cheatsheets.mirror.intra - Developer command references
http://npm.mirror.intra - NPM proxy (if enabled)

To use the APT mirror on your systems, add this to /etc/apt/sources.list:

deb http://mirror.intra/archive.ubuntu.com/ubuntu noble main restricted universe multiverse

Installation

You can download the setup script from the project website:

Visit ui-apt-mirror.dbashkatov.com
Download the setup script
Make it executable and run it:

./install.sh

The setup script will guide you through configuration and deployment. Once running, you'll have access to all four web interfaces for package management, administration, file hosting, and npm proxy.

The project is also available on GitHub.

This article is practical for home servers and infrastructure. It is unlikely that what is described in this article will be relevant for production.

Why would you need an access point on a server?

This will potentially allow you to add one additional level of security by adding a range of addresses to the access point settings that will be issued to clients via dhsp. Then you can use the firewall settings to limit the use of some services only for clients with an IP address from your access point's pool.
You can get an additional connection channel to your home server for those cases when the main router does not work for some reason.
Since your home server will be able to operate in a mode where it does not need intermediate devices for connection, you will be able to increase its portability. You can take your home server with you on a business trip (if it is compact), and you can operate with data on it without having a travel router with you, and without connecting it to routers in hotels.

Installing the required package

sudo apt-get install network-manager

Getting the name of a WiFi device

ls /sys/class/ieee80211/phy0/device/net/

Adding a configuration section to the netplan config

  renderer: NetworkManager\n  wifis:\n    wlx90de80f97ff1: # Here you need to you your wifi device name\n      optional: true\n      dhcp4: true\n      addresses: [192.168.10.1/24] # DHCP ip range\n      access-points:\n        "drx3": # Wifi network name\n          auth:\n            key-management: psk\n            password: "testpw" # Use a stronger pw\n          mode: ap\n          band: 5GHz\n          networkmanager:\n            passthrough:\n              wifi-security.proto: "rsn"

Applying your new AP config

sudo netplan apply

Now you will be able to connect to your homeserver directly via wifi.
