The python3-pydantic package is in the universe repository in Ubuntu 20.04 and later. Install the python3-pydantic package from Ubuntu 20.04 in Ubuntu 18.04 with the following commands:

sudo apt update
wget http://mirrors.kernel.org/ubuntu/pool/universe/p/pydantic/python3-pydantic_1.2-1_all.deb
sudo apt install ./python3-pydantic_1.2-1_all.deb

  • I found out the problem. Python3-Pydantic is only in Ubuntu 20.04 but not for Ubuntu 18.04 and lower. That's how I got the error. How can it be available if not listed for Ubuntu 18.04

  • python3-pydantic is not available directly from the repositories of 18.04, so you need to manually download it with wget http://mirrors.kernel.org/ubuntu/pool/universe/p/pydantic/python3-pydantic_1.2-1_all.deb I know it's from the 20.04 repositories, but it works in 18.04 too, so manually download it anyway.
