Oh, when you said you never used this software, I thought we were talking about GnuPG. So, above, I tried to help show you the version of GnuPG that you are using to run the GNU Privacy Assistant application on Debian Linux.
I got it. No problem. It is also true that I didn't use GnuPG before the day I installed it. As I already said, I am new to Linux and have never used macOS. I have used Cleopatra in Windows for PGP and OpenKeychain for Android. I was already happy with Cleopatra, but as you can see now, I have tried these OS just because I wanted to write a tutorial and try Linux for security purposes.
I'm a macOS user. The command line in the macOS Terminal is almost the same as the command line in the Linux Terminal that you use.
Interesting. Recently, I was about to buy a used Macbook Pro but then came to know it's too outdated, and if I want to repair something, I have to spend a lot of money on it. So, I went for another Lenovo Laptop besides my desktop.
