Hi there!

I'm getting an error from pyhton when i want to add an apt-repository.

I have already installed the package python-software-properties, but this is my terminal output:

Code:
root@kali:~# add-apt-repository ppa:danielrichter2007/grub-customizer
You are about to add the following PPA to your system:

Anyone knows anyway to solve this? Thanks in advance!
