I have followed this tutorial to remove PostgreSQL : https://www.squash.io/step-by-step-process-to-uninstall-postgresql-on-ubuntu/
Then I tried to reinstall it with sudo apt-get -y install postgresql.
The following error occurs:

I tried
sudo apt-get clean,
sudo apt autoremove,
sudo apt-get install --reinstall postgresql-client-common.
sudo apt remove --purge postgresql-common
sudo apt-get -f install postgresql-client-common
sudo apt-get -f --fix-broken install postgresql-common
Nothing works until now.
Thanks a lot for the help !
