Understanding the Issue

When you install Anaconda on Ubuntu, it modifies the .bashrc file to activate the base environment each time a new terminal session is started. While this can be convenient for some, it can also lead to confusion and unwanted behavior for others. If you’re among those who prefer to manually activate your Anaconda environments, read on to learn how to prevent the terminal from automatically starting with the Anaconda base environment.

Step-by-Step Solution

Here’s a step-by-step guide to correct this behavior:

1. Open the .bashrc file

   Open your terminal and type the following command to open the .bashrc file in a text editor:

   nano ~/.bashrc
   

2. Locate the Anaconda script

   Scroll down to the end of the file and locate the following lines:

   # added by Anaconda3 installer
   # __conda_setup="$('/home/username/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
   # if [ $? -eq 0 ]; then
   #     eval "$__conda_setup"
   # else
   #     if [ -f "/home/username/anaconda3/etc/profile.d/conda.sh" ]; then
   #         . "/home/username/anaconda3/etc/profile.d/conda.sh"
   #     else
   #         export PATH="/home/username/anaconda3/bin:$PATH"
   #     fi
   # fi
   # unset __conda_setup
   

3. Comment out the Anaconda script

   Comment out the lines related to Anaconda by adding a # at the beginning of each line. This will prevent the script from running when you start a new terminal session.

4. Save and exit

   Press Ctrl+X to exit, then Y to save the changes, and finally Enter to confirm.

Verifying the Solution

To verify that the changes have taken effect, close your terminal and open a new one. The Anaconda base environment should no longer be activated by default. You can confirm this by typing:

conda info --envs

The asterisk (*) should be next to the base environment, indicating that it is not currently active.

Conclusion

In this post, we’ve walked through the steps to prevent the Ubuntu terminal from automatically starting with the Anaconda base environment. This simple tweak can help streamline your workflow and reduce confusion when working with multiple Anaconda environments. Remember, you can still manually activate the base environment at any time by typing conda activate base.
