Sorry if it sounds a dumb question but I always thought using the official playstore that comes pre-installed is the safest so everything related to F-Droid is new to me. Did anyone had apprehension on installing F-Droid when you had bare to none knowledge how it works? I like to be cautious and on the page it has a Instructions to verify the download page and it only tells how to check from Linux but not from Android, what am I missing here?
To be honest, I didn’t verify the signature when I installed it. The download is over TLS (HTTPS) so you know you have a secure connection with the F-Droid server during the download. But because of the tiny chance the F-Droid website was hacked at the time you download it, you should verify the signature.
