# The second one show 3.10 as version as it is provided by ubuntu as default
python --version
python3 --version

sudo add-apt-repository ppa:deadsnakes/ppa

# This might take more than few minutes
sudo apt update
sudo apt upgrade

# Install python 3.11
sudo apt-get install python3.11

# python3 shows 3.10 and python3.11 shows 3.11 as version
python3 --version
python3.11 --version

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.11 2

You might get error “ModuleNotFoundError: No module named ‘apt_pkg’” when “sudo apt update” was executed later. Such error can also occured when installing azure-cli. One solution could be:

cd /usr/lib/python3/dist-packages/
cp apt_pkg.cpython-310-x86_64-linux-gnu.so apt_pkg.so

2. Install pip

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

python get-pip.py

python -m pip --version

# You can also do this for ~/.zshrc
nano ~/.bashrc
# add this line to the end of file, save and exit the file
alias pip='python -m pip'

pip --version

pip install --upgrade pip
