In general, the installation steps can differ greatly for each Linux distribution used. It is therefore strongly recommended to check the installation requirements for the Linux systems here.
For the following instructions, the current Ubuntu desktop version (21.04) is used.

The Anaconda package is provided in the form of an installation script, that must be run in the terminal with bash:

You have to confirm your installation intentions with „yes“ a few times during the installation. Afterwards one activates conda with the input in terminal.

Miniconda is provided for Linux only as bash-script. The bash-script can be executed in Terminal with „bash“. It is recommended to answer the prompt „Do you wish the installer to initialize Anaconda3 by running conda init?“ with „Yes“. This integrates the conda input into the terminal. To activate the terminal integration outside of the bash-script, you have to enter the following (Conda path has to be customized accordingly):

source *path to Conda*/bin/activate

.

And then:

conda init

This will seamlessly integrate the Conda input into the terminal and you can proceed with setting up the project-specific Python environment!

As with the Windows installation!
