Solution

Compile Python 3.8 directly on the server.

# Install dependencies for building Python
sudo apt update
sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev wget

# Download Python 3.8
cd /tmp
wget https://www.python.org/ftp/python/3.8.18/Python-3.8.18.tgz
tar -xf Python-3.8.18.tgz
cd Python-3.8.18

# Configure and compile
./configure --enable-optimizations
make -j $(nproc)

# Install (this will take some time)
sudo make altinstall

# Verify installation
python3.8 --version
