You are getting an error because you have not installed Python 2.7
Do the following commands:git clone https://github.com/demining/CryptoDeepTools.git
cd CryptoDeepTools/02BreakECDSAcryptography/
sudo apt install python2-minimal
wget https://bootstrap.pypa.io/pip/2.7/get-pip.py
sudo python2 get-pip.py
pip2 install -r requirements.txt
Run the script next!I don't know why you assumed i didn't install Python 2.7 on my OS. Python 2.7 was released on 2010[1] and my earlier post was posted on 2022. No linux distro on 2022 ship Python 2 with sub version lower than 2.7. Even Debian 7.0 contain Python 2.7[2].
