Context
I'm using Ubuntu 20.04.2 LTS.
Before running the command I had several python version:
- python2.7.18 (
python) - python3.6 (
python3) - python3.7.4 (
python3.7) - python3.8.0 (
python3.8)
Problem
I wanted to remove python3.8.0, so I ran $ sudo apt remove python3.8 (output below), and now I still have every python version except that python3 point now to python3.8.8.
And I lost the GUI, I now use tty to access the terminal. It seems that I have important dependecies problems as I'm unable to reinstall gnome or ubuntu-desktop.
I tried some answers of similar questions but none of them worked (listed below).
Complete tracebacks
As the outputs of the commands I tried are too long I can't post them with the question, so I created a github repo with complete traceback of every tried command.

What I tried
Removed Python 3 and now Ubuntu Software Center, terminal and other applications don't work
Command $ sudo apt-get install python3-all
Output
Les paquets suivants contiennent des dépendances non satisfaites :
python3-all : Dépend: python3 (= 3.8.2-0ubuntu2) mais ne sera pas installé
Dépend: python3-distutils (>= 3.8.2-1~) mais ne sera pas installé
Dépend: python3.8 mais ne sera pas installé
E: Impossible de corriger les problèmes, des paquets défectueux sont en mode "garder en l'état"
Removed python3 hoping to reinstall it, but cannot do it
Command
I first installed aptitude $ sudo apt install aptitude
and then ran $ sudo aptitude install python3
Output
Les paquets suivants ont des dépendances non satisfaites :
python3.8 : Dépend: python3.8-minimal (= 3.8.5-1~20.04.2) but 3.8.8-1+bionic2 is installed
Dépend: libpython3.8-stdlib (= 3.8.5-1~20.04.2) but 3.8.8-1+bionic2 is installed
Why did removing 'python3' remove many other important packages?
