А зачем ты venv из pycharm делаешь? Попробуй из консоли
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-get install python3-venv
You may need to use sudo with that command. After installing the python3-venv
package, recreate your virtual environment.
Failing command: ['/mnt/Shared/PyCharmProjects/new1111/bin/python3.6', '-Im', 'ensurepip', '--upgrade', '--default-pip']
