Install Python 3.11 in Ubuntu 20

Python 3.11 Prerequisite Support on Ubuntu 20.04

Ubuntu 20.04’s deadsnakes repository does not provide all the Python 3.11 packages required for our environment. To ensure full compatibility, the necessary Python 3.11 components have been added to the Ubuntu 20 UTILS repository.

The following steps describe how Python 3.11 prerequisites are satisfied on Ubuntu 20.04.

Install the Acceldata UTILS Repository Key and File

wget -qO - https://mirror.odp.acceldata.dev/v2/odp-utils/ubuntu20/my_public.key | sudo apt-key add -

echo "deb [arch=amd64] https://mirror.odp.acceldata.dev/v2/odp-utils/ubuntu20/ ODP main" | sudo tee /etc/apt/sources.list.d/acceldata-staging.list

sudo apt update

Install Python 3.11
