NOTE

The preceding command is applicable to Ubuntu 18.04. For other Ubuntu versions, modify the preceding installation command based on the installation package name. The details are as follows:

Python 3.8 or a later version is required. This section uses Python 3.8 as an example.

Java 8 or later is required. This section uses Java 8 as an example.

Set Python 3.8 as the default Python version.

Check the location of Python 3.8.

which python3.8

Switch Python and Python3 to Python 3.8.

sudo update-alternatives --install /usr/bin/python python {Python 3.8 path} 1    #{Python 3.8 path} is the location of Python 3.8 obtained in the previous step.
sudo update-alternatives --install /usr/bin/python3 python3 {Python 3.8 path} 1   #{Python 3.8 path} is the location of Python 3.8 obtained in the previous step.
