In this article, we will talk about how to install pip on Ubuntu 20.04. To begin, we’ll need to clarify what pip actually is.
Pip is a package manager for Python. It’s normally used to install and manage Python modules on your system.
In case Python is new to you as well, Python is a high-level object-oriented programming language that is becoming increasingly popular over the years. Python is widely used in software development, system administration, scientific and numeric data analysis, and much more.
Both Python 2 or Python 3 can be installed on Ubuntu 20.04. However, with Ubuntu 20.04, the default version is Python 3. If for some reason you need Python 2 along with its version of pip, don’t worry, we’re covering that in this tutorial as well.
Pip is not installed by default on Ubuntu – however, the installation is quite quick and simple. Let’s start with the installation. Installing pip on Ubuntu 20.04 is a fairly easy task and it should be done in less than 10 minutes.

First, you need to login to your Ubuntu 20.04 VPS via SSH as the root user account, or as a user with sudo privileges:
ssh root@Server_IP_Address -p Port_Number
Of course, you will need to replace
Port_Number with your actual server IP address and SSH port number.
By running the following command, all installed packages will be updated and upgraded:
apt update && apt upgrade -y
You can also restart your server to ensure that all of the latest configuration files get read and used.
Install pip for Python 3
We assume that you already have the default Python version installed on your server. To check if Python 3 is already installed on your server, use the command below:
You should get the following output:
root@ubuntu20:~# python3 -V Python 3.8.2
Before proceeding with the installation of pip, it is a good idea to confirm whether pip is already installed on your server. You can do this with the command:
If you get the following output:
Command 'pip3' not found
This means that pip3 is not installed on your server. You can install pip3 by executing this next command:
apt install python3-pip
By executing the above command, all of the dependencies required for pip will be installed along with PiP. When the installation is complete, you can validate the installed pip with the command:
You should have an output similar to the following:
root@ubuntu20:~# pip3 -V pip 20.0.2 from /usr/lib/python3/dist-packages/pip (python 3.8)
Install PiP for Python 2 (optional)
If for some reason you want to use Python 2 instead of the default Python 3 version, you can follow this section of the article.
To install Python 2 you can run the command:
apt install python2
Since PiP for Python2 is not available in the Ubuntu 20.04 repository, in this step we will use the
get-pip.py script. Use the following command to download the
curl https://bootstrap.pypa.io/get-pip.py --output get-pip.py
Now you can execute the script with python2 to install pip for Python 2.
Once the installation is complete, you can verify the pip version with:
If you get the following output:
root@ubuntu20:~# pip -V pip 20.1.1 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7)
Then you have the correct version of pip installed for Python 2.
How to Use pip3
In this step of the article, we will show you a few useful basic pip commands. Now that pip is installed, you can try to use it.
The basic syntax for pip3 is the following:
pip3 <command> [options]
The following examples are the most commonly used pip3 commands.
If you want to install a package:
pip3 install package_name
You can list all installed packages:
Or you can search for a package:
pip3 search package_name
If for some reason you want to remove/uninstall some package, you can use the command:
pip3 uninstall package_name
You can find more options and usage examples by running the help command:
Usage: pip3 <command> [options] Commands: install Install packages. download Download packages. uninstall Uninstall packages. freeze Output installed packages in requirements format. list List installed packages. show Show information about installed packages. check Verify installed packages have compatible dependencies. config Manage local and global configuration. search Search PyPI for packages. wheel Build wheels from your requirements. hash Compute hashes of package archives. completion A helper command used for command completion. debug Show information useful for debugging. help Show help for commands. General Options: -h, --help Show help. --isolated Run pip in an isolated mode, ignoring environment variables and user configuration. -v, --verbose Give more output. Option is additive, and can be used up to 3 times. -V, --version Show version and exit. -q, --quiet Give less output. Option is additive, and can be used up to 3 times (corresponding to WARNING, ERROR, and CRITICAL logging levels). --log Path to a verbose appending log. --proxy Specify a proxy in the form [user:passwd@]proxy.server:port. --retries Maximum number of retries each connection should attempt (default 5 times). --timeout Set the socket timeout (default 15 seconds). --exists-action Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup, (a)bort. --trusted-host Mark this host or host:port pair as trusted, even though it does not have valid or any HTTPS. --cert Path to alternate CA bundle. --client-cert Path to SSL client certificate, a single file containing the private key and the certificate in PEM format. --cache-dir Store the cache data in. --no-cache-dir Disable the cache. --disable-pip-version-check --disable-pip-version-check Don't periodically check PyPI to determine whether a new version of pip is available for download. Implied with --no-index. --no-color Suppress colored output --no-python-version-warning Silence deprecation warnings for upcoming unsupported Pythons.
And if you are interested in some specific command details, you can use the following command:
pip3 <command> --help
