Удаление Python 2.7.12 на ubuntu 18.04 закончилось с неработающими пакетами

Я сделал ужасную ошибку, потому что удалил pyth 2.7 из моей машины ubuntu 18.04, так как хотел оставить только python3, но, к сожалению, были некоторые компоненты, которые были установлены с помощью pip из python 2.7 (например, ansible ).

Теперь, когда я пытаюсь переустановить python, у меня появляется следующая ошибка:

:~$ sudo apt install python
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 python : PreDepends: python-minimal (= 2.7.12-1~16.04) but it is not going to be installed
          Depends: python2.7 (>= 2.7.12-1~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Когда я проверяю остаточную конфигурацию, я вижу следующее:

:~$ apt list | grep residual-config

И когда я проверяю удерживаемые пакеты с помощью dpkg, ничего не появляется:

~$ dpkg --get-selections | grep hold

Моя версия ОС is:

~$ cat /etc/os-release
NAME="Ubuntu"
VERSION="18.04.3 LTS (Bionic Beaver)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 18.04.3 LTS"

Я знаю, что причинил ущерб, и я усвоил это на собственном горьком опыте. Каков же способ переустановки python 2.7.12?

Любая помощь, подсказка или совет будут более чем благодарны.
