Восстановите Ubuntu 18.04 после Удаления Python 3.6

Я хотел обновить свои версии Python, и когда обновление через Кв. ничего не сделало, я решил, что хотел создать новейшие версии Python 2 (2.7.16) и 3 (3.7.2). Прежде чем я сделал это однако, я, к сожалению, решил удалить обе из версий, которые я имел (2.7.15~rc1-1, 3.6.7), таким образом, я в основном уничтожил свою систему. Я мог создать и установить новые версии очень хорошо, но когда я перезапустил, GUI не загружался. Загрузчик все еще работает, и я могу войти в терминал. Но при попытке последовать некоторому совету относительно здесь (как установка рабочего стола человечности), я обнаружил, что не могу соединиться с Интернетом (имена хостов не могут быть разрешены, когда я пытаюсь установить пакеты, и я не могу проверить с помощью ping-запросов www.google.com). Я пытался использовать режим восстановления, где я позволил объединиться в сеть, но никакое различие.

Есть ли шанс, я могу восстановить свою систему? Или есть ли некоторый способ, которым я мог использовать карту с интерфейсом USB установки Ubuntu для сброса системы к "заводским настройкам" (те же разделы и т.д. как прежде), даже если я должен удалить все на там? Я запускаю Windows 10 и Ubuntu 18.04 на двойной загрузке, и даже при том, что процесс установки пошел вполне гладко в первый раз, когда у меня были проблемы прежде с Windows двойной загрузки и Ubuntu на моем ноутбуке, и теперь я боюсь, я мог нанести еще больше ущерба. Я был бы очень счастлив, если кто-то мог бы помочь мне.

Edit#1: кажется, что я все еще имею python3.6-minimal установленный, apt list --installed | grep 'python' выводы:

libpython-stdlib/bionic,now 2.7.15~rc1-1 amd64 [installed,auto-removable]

python3.6-minimal/bionic-updates,now 3.6.7-1~18.04 amd64 [installed]

Также ls /var/cache/apt/archive | grep 'python' дает мне:

python3-apt_1.6.3ubuntu1_amd64.deb
python3-distupgrade_1%3a18.04.30_all.deb
python3-gi_3.26.1-2ubuntu1_amd64.deb

python3-update-manager_1%3a18.04.11.9_all.deb
python-apt-common_1.6.3ubuntu1_all.deb

Я надеюсь, что это помогает.

Я вижу теперь, когда набор действительно важных пакетов был удален. И взглядами моей истории удара, кажется, что я назвал обоих sudo apt remove python и sudo apt remove python3 даже прежде, чем создать более новые версии. Я изменил свой исходный вопрос отразить это.
