Hello! If you're getting an error like "Unable to locate package python3-pip" on Ubuntu 18.04, it usually means either your package list is outdated or your system doesn't have the appropriate repositories enabled.

Let me guide you step by step to install pip for Python 3 properly on Ubuntu 18.04:

✅ Step 1: Update package list

bash
sudo apt update

✅ Step 2: Install python3-pip

bash
sudo apt install python3-pip

If this still gives you an error like "Unable to locate package", try these next steps.

🛠️ Step 3: Add universe repository (optional, in case it's missing)

bash
sudo add-apt-repository universe
sudo apt update

Then try again:

bash
sudo apt install python3-pip

✅ Step 4: Check pip installation

After successful installation, check the version:

bash
pip3 --version

You should see something like:

bash
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)

📝 Bonus Tip: Install pip manually (if apt fails completely)

If all else fails, you can install pip using the official get-pip.py method:

bash
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo python3 get-pip.py
