The process of installing Python3-pip on an Ubuntu 20.04 system should usually be straightforward, but sometimes a few bumps along the road can give rise to common errors needing quick resolution. Here’s how you can fix some of these common issues.
The first step you’ll need to take is to ensure Python3 and its associate package manager pip3 are installed in your system. You can install them using the
apt
command:
sudo apt update sudo apt install python3 python3-pip
On successful execution of the above commands, you’ll have both Python3 and pip3 installed on your system.
Error: Unable to locate package python3-pip
If after running the above installation commands, you encounter an error that says “Unable to locate package python3-pip,” it indicates that the operating system’s package manager (apt), does not have a reference to this particular package.
Use the following steps to resolve this issue:
* Update apt’s package lists by running:
sudo apt update
* Retry installing Python3-pip :
sudo apt install python3-pip
Error: Command ‘pip’ not found
In situations where the installer shows an error message that the ‘pip’ command was not found, often, the environment path is missing, or pip3 was not correctly installed.
To remedy this:
1. Confirm the installation of pip3 by executing:
python3 -m pip --version
If pip3 is installed correctly, you will see the installed version of pip
2. Add pip to the PATH by putting the below line in your ~/.bashrc file:
export PATH=$PATH:/home/your_username/.local/bin/
Note to replace ‘your_username’ with your actual username.
Then source the ~/.bashrc file to apply the changes immediately.
source ~/.bashrc
Lastly, let’s not forget the case where your script may fail due to dependencies that aren’t met. This often leads to modules not being found. For example:
Error: No module named ‘XYZ’
This error occurs when your Python script tries to import a specific module that isn’t installed. The solution is to find the missing package and use pip3 to install it.
pip3 install XYZ
Replacing “XYZ” with the name of the module that’s missing.
Walking through each aforementioned step, you should now have a working Python3 and pip installation on your Ubuntu 20.04 system ready to take on any coding challenge! For more information about managing Python packages, refer to the Python Packaging User Guide.I can’t stress enough the importance of maintaining your Python3-Pip on Ubuntu.

pip3 --version
Now, with pip installed, updating and upgrading is as simple as running a few commands:
To upgrade pip:
python3 -m pip install --upgrade pip
If your active environment uses pip2 and pip3 concurrently, it’s advised to use pip3 dedicated command to avoid pointing pip to older python versions:
pip3 install --upgrade pip
In terms of updates, consider utilizing the
--upgrade
flag when using
install
. This upgrades the packages specified:
pip3 install --upgrade somepackage
In addition, to bulk upgrade all the outdated pip packages, list them with
pip3 list --outdated
, then upgrade each one individually or write a bash script to automate the process.
However, dealing with globally installed packages might lead to permission issues or unintended upgrades of packages not prepared to higher versions. Hence, adopting Python isolated environments, like venv, is good practice.
Also note; ‘upgrading’ and ‘updating’ are often used interchangeably, but they hold different meanings. In the context of maintaining software, ‘updating’ relates to minor revisions and bug fixes within the same version (e.g., going from 1.2.o to 1.2.1), while ‘upgrading’ refers to moving to a new, major version (e.g., going from 1.2.x to 2.0.0).
