Невозможно запустить jupyter вне виртуальной среды и создать другую среду

При попытке запустить его, мой Kernell говорит мне, что нет там module named ipykernel_launcher:

На пользовательском интерфейсе это выглядит так:

Итак, увидев эту ссылку, я попытался удалить IPython и переустановить его, но, похоже, есть некоторые конфликты:

mike@mike-Inspiron-3543:~/Documents/programming/collective$ pip uninstall ipykernel
Cannot uninstall 'ipykernel'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

Действительно, я не знаю, связано ли это, но я установил его в виртуальной среде в другой папке:

(mybotenv) mike@mike-Inspiron-3543:~/Documents/programming/mybot$ python -m pip install ipykernel
Collecting ipykernel
...
Installing collected packages: ipykernel
Successfully installed ipykernel-4.9.0

и это сработало отлично. Но сейчас я не могу создать виртуальную среду:

mike@mike-Inspiron-3543:~/Documents/programming/collective$ python3 -m venv envError: Command '['/home/mike/Documents/programming/collective/env/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.

У меня Ubuntu 16.04 и я использую Python 3
