Additionally, replace &#8216;root&#8217; with the username of the admin account if necessary.<\/p>\n\n\n\n<p>Before starting, you have to make sure that all Ubuntu OS packages installed on the server are up to date. You can do this by running the following commands:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">apt-get update -y\napt-get upgrade -y<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-step-2-install-python-3-9-via-ppa\"><span class=\"ez-toc-section\" id=\"Step-2-Install-Python-39-via-PPA\"><\/span>Step 2: Install Python 3.9 via PPA<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In this section, we will show you how to install Python 3.9 via a third-party PPA.<\/p>\n\n\n\n<p>First, you will need to install some dependencies required to install Python 3.9. You can install all of them with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">apt-get install software-properties-common apt-transport-https gnupg2 -y<\/pre>\n\n\n\n<p>After installing all the dependencies, add the third-party PPA with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">add-apt-repository ppa:deadsnakes\/ppa<\/pre>\n\n\n\n<p>Once the repository is added, update the repository cache and install the Python 3.9 with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">apt-get install python3.9 -y<\/pre>\n\n\n\n<p>Once the installation is completed, you can verify the installed version of Python with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">python3.9 --version<\/pre>\n\n\n\n<p>You should get the following output:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">Python 3.9.1\n<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-step-3-install-python-3-9-from-source\"><span class=\"ez-toc-section\" id=\"Step-3-Install-Python-39-from-Source\"><\/span>Step 3: Install Python 3.9 from Source<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In this section, we will show you how to install the Python 3.9 from the source code. Before installing Python 3.9 from its source code, you will need to install some dependencies required to compile the Python.<\/p>\n\n\n\n<p>You can install all dependencies with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">apt-get install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev -y<\/pre>\n\n\n\n<p>Once all the dependencies are installed, download the latest version of Python source code with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">wget https:\/\/www.python.org\/ftp\/python\/3.9.1\/Python-3.9.1.tgz<\/pre>\n\n\n\n<p>Once the download is completed, extract the downloaded file with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">tar -xf Python-3.9.1.tgz<\/pre>\n\n\n\n<p>Next, change the directory to the extracted directory and configure the Python with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">cd Python-3.9.1\n.\/configure --enable-optimizations<\/pre>\n\n\n\n<p>Next, install the Python 3.9 with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">make altinstall<\/pre>\n\n\n\n<p>Once the installation has been completed, you can verify the installed version of Python using the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">python3.9 --version<\/pre>\n\n\n\n<p>You should get the following output:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">Python 3.9.1\n<\/pre>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignright size-large\"><img decoding=\"async\" width=\"120\" height=\"117\" src=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2021\/01\/installing-python-3.9-on-ubuntu-20.04.jpg\" alt=\"installing python 3.9 on ubuntu 20.04\" class=\"wp-image-35368\" title=\"Installing PHP 8 on Ubuntu 20.04\"\/><\/figure><\/div>\n\n\n\n<p>Of course, you can do none of this if you use one of our <a href=\"https:\/\/www.rosehosting.com\/python-hosting.html\">Python VPS Hosting<\/a> services, in which case you can simply ask our expert Linux admins to setup this for you.
