Well... normal for the 1% of us tech savvy computer users.
This reminds me of a podcast I listened to last night where a physician explained how to get a flu shot: go to your place of work and do it yourself. Of course she was being sarcastic.
Except people who are more tech-illiterate don't do it, and we're the minority here. It shouldn't be normal.
I have a deal with people who I love most. They are NOT allowed to install new software without my supervision. In return, they buy me coffee/treats for the help. It works! I presume this deal will continue to exist until binary signatures become a thing of importance for the end user.
