Ошибки Ubuntu 18.04 Python-TZ и Python-ZMQ

У меня установлена ​​дополнительная версия Python 2.7.15rc1, и я создал некоторую проблему, когда временно изменил символическую ссылку на Python на Python3 и вернулся обратно.

Теперь, когда я пытаюсь получить обновления через apt.

sudo apt update -y && sudo apt upgrade -y 

Это то, что я получаю.

The following additional packages will be installed:
  python-zmq
The following packages will be upgraded:
