As I was following the tutorial on “How To Serve Flask Applications with Gunicorn and Nginx on Ubuntu 20.04” I was prompted to install various packages, such as Certbot for setting up my SSL certificate.
When I did the following command: sudo apt install python3-certbot-nginx
As you can see, the prompt was [Y/n], which made me think I need to type an uppercase Y to say yes. But when I did, the operation aborted. Very confusing. When I tried it again and used a lowercase y, it proceeded.
I will share this as a ticket, but I also want to share it in the community in case others have the same problem.
