To help you properly, I need the actual error message you’re seeing in the terminal when trying to install Containernet. Can you please paste that in full?

Meanwhile, here’s a checklist of common issues and fixes:

Quick Troubleshooting Checklist

  1. Ensure git and docker are installed and running:
sudo apt update
sudo apt install git docker.io
sudo systemctl start docker
sudo systemctl enable docker
  1. Clone and build containernet correctly:
git clone https://github.com/containernet/containernet.git
cd containernet
sudo ./configure.sh   # may prompt to install dependencies
sudo make build
sudo make install
  1. Run with privileges:
  • Use sudo when creating containers and topologies.
  • Ensure your user is in the docker group:
sudo usermod -aG docker $USER
newgrp docker
  1. Check Docker overlay support:
docker info | grep -i overlay

If not enabled, add overlay support or use aufs.
5. Watch configure.sh errors:
The script may fail installing maven, openjdk, net-tools, etc. Install missing packages manually:

sudo apt install openjdk-11-jdk maven net-tools
  1. Look for Python version conflicts:
    Containernet uses Python 3, so confirm with:
python3 --version

But the best next step is for you to paste the exact error output. That’ll help me pinpoint precisely where things are failing.
