When installing SageMath through the terminal on Ubuntu 18.04 on command
sudo apt-get install sagemath
I get a notification:

General type of mail configuration:
Each time I install SageMath, I have to select the [1. No configuration] option.
How do I write a command and make sure that when you run the SageMath installation command, the automatic machine is selected and validated
option [1. No configuration]? This is something like the -y flag convention [../YES]
How can I do it? It's just that it's problematic for me to do this manually, since I launch the installation via a Bash script with other installation packages and programs.
Every time I have to stop at the SageMath setting on this option and enter this number "1" manually.
In GNU/Linux, is there an automatic validation of an option on a specified command?
