CAUTION: All the below commands will COMPLETELY BREAK your OS.

I removed all version by doing :

sudo apt purge python-pip python-dev sudo rm -rf /usr/bin/python* sudo rm -rf /etc/python* sudo rm -rf /usr/local/lib/python* sudo rm -rf /usr/share/man/man1/python* sudo rm -rf /usr/share/python* sudo rm -rf /usr/local/bin/pip*

Now when i try to install again :

sudo apt-get install python3

It detects it is already installed ?

Any idea how to complety remove old versions ?

thanks

The proper course of action after breaking your system so thoroughly is to re-install. You might be able to fix the system by running

dpkg -l | grep python # see what the system think's is installed
sudo mv /var/lib/dpkg/info/python* /tmp/ # get rid of the apt database files
sudo apt-get update
sudo apt-get install *list-of-packages*

where the list-of-packages came from the first command.
