Official Resources
This page collects every official download link, repository, and documentation source for the components that make up an ADL environment. Use only the sources listed here.
Never download Termux or its add-ons from the Google Play Store. The Play Store version is severely outdated, no longer receives updates, and will break when paired with current packages. Likewise, avoid random APK mirror sites (APKPure, APKMirror, etc.) -- they may ship unsigned, tampered, or outdated builds.
Termux
The terminal emulator and Linux environment that forms the foundation of ADL.
Termux (F-Droid)Recommended source. Always up to date and signed by the Termux team. Termux (GitHub Releases)Direct APK downloads from the official repository.The Termux Wiki is the authoritative reference for packages, configuration, and troubleshooting: wiki.termux.com.
Termux Add-ons
All add-ons must come from the same source as Termux itself (F-Droid or GitHub). Mixing sources causes signature mismatches.
Termux:APIAccess Android APIs (camera, sensors, notifications) from the terminal. Termux:StylingCustomize fonts and color schemes for the Termux terminal. Termux:WidgetRun Termux scripts from Android home-screen widgets. Termux:BootExecute scripts automatically when the device boots. Termux:FloatRun Termux in a floating window overlay.Termux:X11
The X11 display server used by ADL to render a full graphical desktop on Android.
Termux:X11 (GitHub Releases)Pre-built APK and companion package for the Termux:X11 display server.Termux:X11 replaces VNC for most ADL setups. It provides lower latency and native Android integration compared to a VNC viewer.
proot-distro
The tool that installs and manages Linux distributions inside Termux without root access.
proot-distro (GitHub)Source repository and issue tracker.You do not download proot-distro manually. Install it inside Termux with pkg install proot-distro, then use proot-distro install ubuntu to set up your distribution.
Ubuntu
UbuntuOfficial Ubuntu website and release information.Ubuntu is installed through proot-distro, not downloaded as a standalone image. The proot-distro install ubuntu command fetches the correct rootfs automatically from official mirrors.
XFCE Desktop
The lightweight desktop environment used by default in ADL.

XFCE is installed via apt inside the proot Ubuntu environment. No separate download is required.
PulseAudio
Provides audio output from the Linux environment to the Android host.

Documentation and Community

| Termux Subreddit | r/termux |
| Termux Discord | discord.gg/termux |
| XDA Forums | xda-developers.com |
When troubleshooting, search the Termux Wiki first, then the subreddit. Most common issues have already been documented in one of these two places.
Verifying Downloads
Always verify that downloaded APKs are authentic before installing them.
Check SHA256 Checksums
After downloading an APK from GitHub Releases, compare its SHA256 hash against the value published in the release notes:
sha256sum termux-app_v0.118.0+github-debug_arm64-v8a.apk
Use Official Sources Only
Stick to F-Droid and GitHub Releases. Both platforms verify package signatures before distribution. F-Droid builds packages from source and signs them with its own reproducible-build pipeline.
Check Signing Keys (F-Droid)
F-Droid packages are signed with the Termux team's key. If you install via F-Droid, the client verifies signatures automatically. When sideloading from GitHub, ensure the APK is signed by the same key used across all official Termux releases.
If Android warns about a signature mismatch when updating, do not proceed. Uninstall the existing version first (this will clear Termux data), then install from the correct source. A signature mismatch means the old and new APKs came from different sources.
