pkg update hangs after adding root-repo. Solution: The GPG key might be outdated. Run:

pkg update && pkg upgrade -y This package doesn’t install actual tools—it adds the repository URL and GPG key to Termux’s sources list.

But for the power user, this is only half the story. Once you unlock your device’s bootloader and gain , a new dimension of Termux opens up: The Root Repository ( root-repo ) .

In this post, we’ll explore what the root-repo is, why it’s different from the standard repositories, how to set it up safely, and the specific tools that turn Termux into a system administration powerhouse. By default, Termux installs its packages from the main , x11 , and science repositories. These packages are compiled to run within Termux’s prooted (pseudo-root) environment. They live in /data/data/com.termux/files/usr and cannot touch system files outside their sandbox. pkg update hangs after adding root-repo

| Package | Command | What it does (with root) | | :--- | :--- | :--- | | tcpdump | su -c tcpdump | Capture network packets for debugging or security analysis. | | nmap | su -c nmap -sS | Perform stealth SYN scans on your local network. | | fstrim | su -c fstrim -v /data | Tell SSD/eMMC storage to garbage-collect unused blocks. | | iw | su -c iw dev wlan0 scan | Scan Wi-Fi channels (replaces deprecated iwconfig ). | | msmtp | su -c msmtp | Send system alerts via email as root. | | htop | su -c htop | View all processes, including system daemons. | | openssh (root use) | su -c ssh | SSH as root (disable password auth for security!). | Running commands as root is like giving someone the keys to your entire kingdom. Follow these rules: 1. Never Run su -c Unnecessarily Bad: su -c ls (just use ls normally). Good: Only use su -c for commands that truly need root. 2. Avoid su -c "bash" (Interactive Root Shell) If you type su -c bash , you’ll drop into a persistent root shell. One wrong rm -rf /* and your device is a brick. If you need multiple root commands, use:

pkg install root-repo Note: On some Termux versions, you might need to run pkg update again after this step to refresh the package list. Check that the root repository is now active: Published by: TermuxTech Insights Reading Time: 6 minutes

su -c "tcpdump -i wlan0 -c 10" Termux will ask for root permission (via Magisk/SuperSU). Grant it, and you’ll see raw packet data. Congratulations—you’ve just used the root repo! Once root-repo is active, explore these powerful tools:

pkg list-repositories You should see an entry like: root https://packages.termux.org/apt/termux-root root stable Try installing tcpdump , a classic network diagnostic tool.
