Beginner needs help figuring out .tar

Thanks for the help @Kerasit and @devnull.
I’ve made some progress, but could am going to need more help to get his working. So far I’ve gotten the image written to the SD card, stuck the SD card into the pi and a bunch of text scrolled across the screen and then the message “Which user would you like to rename?”
I changed the user name and set a password.
Debian GNU/Linux11 nextcloudpi tty1came up and then asked for my login and password

I logged in and then got the message “NextCloudPi v1.52.0 is outdated update to v1.52.1 through ‘ncp-config’ or type ‘sudo ncp-update’
Wi-Fi is currently blocked by rfkill.
Use raspi-config before use”

I tried ‘ncp-config’ and ‘sudo ncp-update’ and got the message “-bash: sudo ncp-config: command not found”

I’m at a loss for what to do now. I’m beginning to think I’m either in over my head or that I downloaded the wrong image and I need to start over.
I’ve been trying to follow the instructions on How to access NextcloudPi first time & Activation and was expecting a web interface, but so far I’ve only seen the text interface. If anyone can tell me what I’m doing wrong, how to get back on track or point me to a more straightforward guide for setting up nextcloudpi I will really appreciate it.

I’ve tried everything I can think of, but am not having any success so far.

Thanks for any help.
