Here’s how to install Python 3.11 in Ubuntu and related distros.** + +![][1] + +Python 3.11 was released on Oct 25, 2022, and claims to be 10-60% faster than the prior [Python 3.10][2] version. + +As always, the feature and improvement list are significantly high in 3.11. Here’s a brief. + +- Error tracebacks are not more definite, which gives you an exact statement that causes the error. +- Introduction of exception groups and new except* syntax +- You can add custom text in the base expression for better error handling in your code. +- Introduction of Variadic generic to allow array-like structure in numerical Python libraries )such as NumPy) +- Dictionary type TypedDict gets improvement where you can now specify whether individual dictionary items are mandatory or optional. +- Introduction of Self annotation, which allows classes to return their own type instance. + +And many more, which you can read in detail on the official [3.11 highlights page][3]. + +### Current Python versions in Linux Distros + +[Ubuntu 22.04 LTS][4] have Python 3.10, whereas the recently released [Ubuntu 22.10 Kinetic Kudu][5] also have the same. However, Kinetick Kudu will probably feature 3.11 within a few weeks. + +Also, [Fedora 37][6] (planned for Nov 1) already has the Python 3.11 RC2 and will get the version. + +So, if you are running Ubuntu 22.04 LTS, [Linux Mint 21][7] or any Ubuntu-LTS-based distros, here’s how you can install Python 3.11 via a PPA. + +**Note**: Use this method with caution. Make sure you know what you are doing because replacing the base Python version of a Linux distribution may cause an unstable system. Many default applications and packages depend on the 3.10 version. + +### How to install Python 3.11 in Ubuntu and related distros + +- Open a terminal prompt and add the following PPA. + +``` +sudo add-apt-repository ppa:deadsnakes/ppa +``` + +- Refresh the cache using the below command. + +``` +sudo apt update  +``` + +- And install Python 3.11 using the below command. + +``` +sudo apt install python3.11 +``` + +![Install Python 3.11 in Ubuntu 22.04 LTS][8] + +Install Python 3.11 in Ubuntu 22.04 LTS + +### Set Default Python Versions + +In theory, you can install multiple versions of Python in Linux distros, but the default can only be one version. Setting up Python 3.11 as default requires some additional steps. Follow along. + +However, before you do that, make sure you know which applications depend on Python 3.10. You can easily find it out using `apt-cache rdepends` command as below. + +``` +debugpoint@debugpoint-22-04:~$ apt-cache rdepends python3.10 +python3.10 +Reverse Depends: +python3.10-dbg +python3.10-venv +python3.10-full +libpython3.10-testsuite +idle-python3.10 +idle-python3.10 +python3.10-minimal +python3.10-doc +python3.10-dev +python3 +virtualbox +python3.10-venv +python3.10-full +libpython3.10-testsuite +kitty +idle-python3.10 +idle-python3.10 +python3.10-minimal +python3.10-doc +python3.10-dev +python3.10-dbg +python3-uno +python3-all +python3.10-dbg +virtualbox +stimfit +python3.10-venv +python3.10-full +python3-stfio +python3-escript-mpi +python3-escript +python3-csound +plasma-firewall +pitivi +obs-studio +liferea +libpython3.10-testsuite +libglib2.0-tests +kitty +idle-python3.10 +idle-python3.10 +cluster-glue +atac +rhythmbox-plugins +python3.10-minimal +python3.10-doc +python3.10-dev +python3 +python3-uno +python3-all +gedit +``` + +#### Use Python 3.11 as the default Python3 + +- First, check the current default version using the below command from the terminal. + +``` +python3 --version +``` + +- Use `update-alternatives` to create symbolic links to `python3` + +``` +sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 1 +``` + +``` +sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.11 2 +``` + +- And choose which one to use as Python3 via the command: + +``` +sudo update-alternatives --config python3 +``` + +![Setting up default python version to 3.11][9] + +Setting up default python version to 3.11 + +Now you can start using the latest Python in your current Ubuntu version for your work/study.
