RockPi4 with Penta hat 3.5

I installed the OS rockpi4b_debian_buster_xfce4_arm64_20210126_0032-gpt.img on to a miroSD card. Am I running the correct OS?

Once logged in I ran “curl -sL | sudo -E bash -”. I then have to install bash and curl. I try “curl -sL | sudo -E bash -” again and I get an error “Unable to locate package rockpi4b-rk-u-boot-latest”

It there a complete list of prerequisite I have to complete before setting up the penta hat?

This is my output

rock@rockpi4b:~$ curl -sL | sudo -E bash -
