Install Python 3.8.3 in Ubuntu 20.04 LTS

First, we need to download the package from the official website of Python. So, on the Homepage of Python’s website –> Downloads drop down menu –> Open All releases. And, look for Python 3.8.3 and Open Download web address against it. Scroll down the page and look for Files section – open the web address that mentions – Gzipped source tarball.

The package we downloaded was – Python-3.8.3.tgz (approximately 23 MBs in size).

Next, use the tar command-line utility to extract contents of the package –

tar -xvf Python-3.8.3.tgz

It will create Python-3.8.3/ in the current directory.

Use cd command-line utility to get inside the directory –

cd Python-3.8.3/

and, issue following commands –

make test

Lastly, we have got two options –

  1. Either we replace already installed version 3.8.2 of Python
    sudo make install

    To verify for the Python version installed –

    python3 -V
  2. Install Python v3.8.3 alongside the Python v3.8.2
    sudo make altinstall

    To check for Python version –

    python3 -V
    python3.8 -V

While installing the package, we encountered an error

zipimport.ZipImportError: can't decompress data; zlib not available

This was resolved by installing the package – zlib1g-dev

sudo apt install zlib1g-dev
