Anaconda is a popular Python/R data science and machine learning platform, big data processing, predictive analysis, and scientific computing.

The Anaconda distribution comes with 250 open source data packages, and more than 7,500 packages can be installed from the Anaconda software source. It also contains a command line tool and a graphical user interface called "Anaconda Navigator".

This guide will explain to you the installation process of Anaconda Python distribution on Ubuntu 20.04.

One, install Anaconda

At the time of writing this article, the latest binding version of Anaconda is 2020.02. Before downloading the installation script, browse the download page, and check if there is an updated Anaconda available.

Complete the following steps on Ubuntu 20.04 to install Anaconda.

Anaconda Navigator is a GUI based on QT. If you install Anaconda on a desktop machine and you want to use GUI applications, install the following packages. Otherwise, skip the steps below.

sudo apt install libgl1-mesa-glx libegl1-mesa libxrandr2 libxrandr2 libxss1 libxcursor1 libxcomposite1 libasound2 libxi6 libxtst6

Use your browser or wget to download the Anaconda installation script:

wget -P /tmp https://repo.anaconda.com/archive/Anaconda3-2020.02-Linux-x86_64.sh

The download will take some time, depending on your internet speed.

This step is optional, but we recommend that you verify the data integrity of the script.

Use the sha256sum command to display the checksum of the script:

sha256sum /tmp/Anaconda3-2020.02-Linux-x86_64.sh

The output is similar to:

2 b9f088b2022edb474915d9f69a803d6449d5fdb4c303041f60ac4aefcc208bb  /tmp/Anaconda3-2020.02-Linux-x86_64.sh

Make sure that the hash value printed by the above command is the same as the Anaconda hash value of the corresponding version of the Anaconda with Python 3 on 64-bit Linux page page.

https://docs.anaconda.com/anaconda/install/hashes/Anaconda3-2020.02-Linux-x86_64.sh-hash/

Run the script to start the installation process:

bash /tmp/Anaconda3-2020.02-Linux-x86_64.sh

You should see the following output:

Welcome to Anaconda3 2020.02

In order to continue the installation process, please review the license
agreement.
Please, press ENTER to continue>>>

Press ENTER to continue. Swipe down to read the agreement and use the ENTER button. Once you have read the agreement, you will be asked whether to accept the terms of the agreement:

Do you approve the license terms?[yes|no]

Enter yes to accept the agreement, and you will be prompted to choose the installation path:

Anaconda3 will now be installed into this location:/home/linuxize/anaconda3

 - Press ENTER to confirm the location
 - Press CTRL-C to abort the installation
 - Or specify a different location below

The default location should be directly available to most users. Press Enter to confirm the position.

The installation process will take some time, and once completed, the script will ask you if you want to run conda init. Enter yes.

Installation finished.
Do you wish the installer to initialize Anaconda3
by running conda init?[yes|no]

This will add the command line tool conda to the system's PATH environment variable.

To activate Anaconda, you can close and reopen your shell or enter the following command in the current shell session to reload the PATH environment variable:

source ~/.bashrc

To verify the installation process, enter conda in your terminal.

that's it. You have successfully installed Anaconda on your Ubuntu machine, and you can start using it.

If you install Anaconda on a desktop system, enter anaconda-navigator in the terminal to open the Navigator GUI:

Two, upgrade Anaconda

Upgrading Anaconda is a very straightforward process. Open your terminal and enter:

conda update --all

If there is an update, conda will display a list and prompt you to confirm whether to update:

The following packages will be UPDATED:

 anaconda-navigator                          1.9.12-py37_0 -->1.9.12-py37_1
 conda                                        4.8.2-py37_0 -->4.8.3-py37_0
 conda-package-han~1.6.0-py37h7b6447c_0 -->1.6.1-py37h7b6447c_0

Proceed([y]/n)?

It is a good idea to upgrade Anaconda regularly.

Three, uninstall Anaconda

If you want to uninstall Anaconda from your Ubuntu system, remove the Anaconda installation directory and other files created during the installation process:

rm -rf ~/anaconda3 ~/.condarc ~/.conda ~/.continuum

Open ~/.bashrc and remove Anaconda from the environment variables:

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init'!!
__ conda_setup="$('/home/linuxize/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"if[ $?-eq 0]; then
 eval "$__conda_setup"elseif[-f "/home/linuxize/anaconda3/etc/profile.d/conda.sh"]; then
  ." /home/linuxize/anaconda3/etc/profile.d/conda.sh"elseexport PATH="/home/linuxize/anaconda3/bin:$PATH"
 fi
fi
unset __conda_setup
# <<< conda initialize <<<
