Creating virtual environment '~/.virtualenvs/r-reticulate' ... 
+ /usr/bin/python3.12 -m venv /home/hornik/.virtualenvs/r-reticulate
The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt install python3.12-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.
