How to completely uninstall python 2.7.13 on Ubuntu 16.04

I installed Python 2.7.13 on Ubuntu 16.04 according to this guide, and it became the default version as an alternative to the version 2.7.12. But, I wanted to completely remove Python 2.7.13 and return back to the version 2.7.12 as the default version since the pip command does not work with the following error.

bash: /usr/local/bin/pip: /usr/bin/python: bad interpreter: No such file or directory 

Could you please help me how to completely remove Python 2.7.13 from Ubuntu 16.04? Otherwise, could you please suggest how to fix the above error?

before doing anything else i suggest you run $ sudo apt install —reinstall python python-apt python2.7-minimal ; ubuntu relies on a working python2 installation! and your question might be better suited here: askubuntu.com

# Remove python2 sudo apt purge -y python2.7-minimal # You already have Python3 but # don't care about the version sudo ln -s /usr/bin/python3 /usr/bin/python # Same for pip sudo apt install -y python3-pip sudo ln -s /usr/bin/pip3 /usr/bin/pip # Confirm the new version of Python: 3 python --version 

In my case, instead of sudo apt purge -y python2.7-minimal this sudo apt purge python2.7-minimal worked!! But after pressing Enter key I have to type Yes, do as I say! N.B. I’m using this in Linux Mint 19.3 not Ubuntu. Thanks @Benoit Mrx

Yes!! But simple it did not word using -y!! Idk why but it worked only giving permission by retyping the confirm string Yes, do as I say!

caution : It is not recommended to remove the default Python from Ubuntu, it may cause GDM(Graphical Display Manager, that provide graphical login capabilities) failed.

To completely uninstall Python2.x.x and everything depends on it. use this command:

sudo apt purge python2.x-minimal 

As there are still a lot of packages that depend on Python2.x.x. So you should have a close look at the packages that apt wants to remove before you let it proceed.

Thanks, I hope it will be helpful for you.

try following to see all instances of python

whereis python which python 

Then remove all instances using:

sudo apt autoremove python 

repeat sudo apt autoremove python(for all versions) that should do it, then install Anaconda and manage Pythons however you like if you need to reinstall it.

can’t uninstall in a such way. anyway it’s remain in the system. sudo apt autoremove python Reading package lists. Done Building dependency tree Reading state information. Done Package ‘python’ is not installed, so not removed 0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded. then again: sudo apt remove python2.7 then: python —version output: Python 2.7.12

this command removed some of the dependencies of my GUI and made my ubuntu-desktop stop working, this also removed google-chrome-stable and another packages. I really don’t know why I run it, heheh

If I’m not wrong autoremove will remove the packages or dependencies which are no longer needed in the environment.

sudo apt purge python2.7-minimal 

Sometimes you need to first update the apt repo list.

sudo apt-get update sudo apt purge python2.7-minimal 

This is what I have after doing purge of all the python versions and reinstalling only 3.6.

root@esp32:/# python Python 3.6.0b2 (default, Oct 11 2016, 05:27:10) [GCC 6.2.0 20161005] on linux Type "help", "copyright", "credits" or "license" for more information. >>> root@esp32:/# python3 Python 3.8.0 (default, Dec 15 2019, 14:19:02) [GCC 6.2.0 20161005] on linux Type "help", "copyright", "credits" or "license" for more information. 

Also the pip and pip3 commands are totally f up:

root@esp32:/# pip Traceback (most recent call last): File "/usr/local/bin/pip", line 7, in from pip._internal.cli.main import main File "/usr/local/lib/python3.5/dist-packages/pip/_internal/cli/main.py", line 60 sys.stderr.write(f"ERROR: ") ^ SyntaxError: invalid syntax root@esp32:/# pip3 Traceback (most recent call last): File "/usr/local/bin/pip3", line 7, in from pip._internal.cli.main import main File "/usr/local/lib/python3.5/dist-packages/pip/_internal/cli/main.py", line 60 sys.stderr.write(f"ERROR: ") ^ SyntaxError: invalid syntax 

I am totally noob at Linux, I just wanted to update Python from 2.x to 3.x so that Platformio could upgrade and now I messed up everything it seems.

Uninstall Python in Ubuntu 22.04

Python is one of the most popular programming languages. It’s an interpreted general-purpose programming language with an emphasis on simplicity. Because of its versatility, Python is used for various purposes: web development, data analysis, artificial intelligence, and much more.

In this guide, we will have a look at uninstalling Python in Ubuntu 22.04.

Prerequisites

To follow this guide, you need the following components:

• A properly-configured Linux system. Learn more about setting up an Ubuntu virtual machine on VirtualBox.
• Access to a non-root user with sudo privilege. Check out the article on using sudoers to manage the sudo privilege.

Python Major Releases

As of now, the two major versions of Python are:

Python 2 received its last update (v2.7.18) on April 20, 2020. It’s been mostly phased out in favor of Python 3. This move, however, caused a major uproar in the community. Python 2 was so popular that the EOL had to be pushed multiple times into the future.

Although deprecated, you may still come across some Python 2 installations for compatibility reasons. By default, Ubuntu comes with installed Python 3.

Method 1: Removing Python Using APT

Step 1: Finding the Installed Python Package

Run the following commands:

• We ask the Python executable to print its version.
• Ubuntu 22.04 comes with pre-installed Python 3. So, the first command returns a version number.
• Ubuntu 22.04 doesn’t come with pre-installed Python 2. So, the expected result is an error. However, if the command returns a version number, Python 2 is later installed.

On Debian/Ubuntu, the core Python packages are as follows:

Step 2: Uninstalling Python

Now that we know what Python version is currently installed on the system, we can start to work on uninstalling them.

To remove Python 2, run the following command:

To remove Python 3, run the following command:

Optional: Remove All Python Packages

Removing all the Python-related packages is generally not recommended since various parts of the system depend on them. If you wish to proceed, ensure that you backed up all your important data.

To remove all the Python packages from the system, run the following command:

• The APT package manager looks for packages that match the given regular expression (*python*). The matching packages are marked for removal.
• APT also marks the dependencies of those packages for removal.

Method 2: Removing Python from the Source

If Python was compiled and installed from its source code, APT won’t be able to recognize the installation. In that case, the uninstallation process will be different.

Assuming you still have the source directory which contains the compiled Python package, run the following commands:

If you removed the source directory, you could try removing the installed libraries and binaries manually:

Note that this is meant to be the last resort. It may lead to corrupted and broken configurations throughout the system.

Method 3: Removing PyPy

PyPy aims to be a replacement for CPython (the default Python implementation). It’s built with RPython which was simultaneously developed with it. The key advantage to using PyPy other than CPython is performance. Although it’s an implementation of Python, certain differences can impact compatibility. Learn more about PyPy.

Similar to the classic Python, PyPy also has two major releases:

To install PyPy, run the following commands:

Similarly, to uninstall PyPy, run the following commands:

Bonus: Removing PIP

PIP is the de-facto standard package manager for Python packages/modules. By default, it’s configured to use the Python Package Index as the source of packages. Starting from Python 3 (v3.4 and later), PIP comes pre-installed with Python 3. The term “PIP” is a recursive acronym for “PIP Installs Packages”. Learn more about PIP.

Similar to the Python major releases, PIP has unique versions for both Python 2 (python-pip) and Python 3 (python3-pip).

If you removed all the Python packages, PIP is also uninstalled by default. However, if you desire to specifically uninstall PIP, run the following commands:

Conclusion

We demonstrated the multiple ways of removing Python from Ubuntu 22.04. We demonstrated uninstalling both CPython and PyPy from the system using APT. We also discussed uninstalling Python if it is installed from the source code.

How to Uninstall Python

We may want to remove Python in our Linux or Windows systems for different reasons – conflicting packages and the need for a given Python version are some top reasons. Unlike in Windows, Python is a core program in most Linux distributions. In this case, uninstalling Python without utmost care may cause your Linux system to break. This article focuses on how we can safely remove Python from Windows and Linux systems.

How to Uninstall Python in Linux

Most Linux distros come with Python installed. In fact, in most cases, the default Python coming with the operating system is a core package for the system such that if it is removed, the graphical display manager breaks down, among other awful things. Other Python version(s) can also be installed alongside Linux-inbuilt Python (we will discuss how to do this later). We can safely remove the Python built from the source, but removing the Python that came with the distribution is not recommended.

To uninstall Python installed from the source, follow these steps:

Step A. First of all, check all the Python versions installed using the whereis command in Linux

From Figure 1, what we are after are the binaries. They are located at bin/or local/bin. The inbuilt Python is in bin/, whereas the Python built from the source is mainly installed at the local/bin. In our case, we have Python3.9 (inbuilt – we don’t want to uninstall this) and Python3.6 located in local/bin directory, and we can safely remove it.

The following list can fully explain the Linux directories we are interested in:

• /bin – binary or executable programs.
• /lib – it contains kernel modules and a shared library.
• /usr – user-related programs.
• The /usr/local directory is where locally compiled applications are installed by default, preventing them from mucking up the rest of the system.
• /etc – system configuration files.

Misc A: Why it is not recommended to uninstall Python at /usr/bin

Many programs in most Linux distributions depend on pre-installed Python. You can identify the default Python by running python on the terminal. You can also find it by using which command.

If we take a closer look at the long listing of /usr/bin you will realize that Python and its dependencies are linked to other programs.
