pg_autoctl do command Issue

Hi,

I am using the below version pg_autoctl
[postgres@testbed13 ~]$ pg_autoctl version
pg_autoctl version
pg_autoctl extension version 2.1
compiled with PostgreSQL 16.1 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 11.4.1 20230605 (Red Hat 11.4.1-2), 64-bit
compatible with Postgres 11, 12, 13, 14, 15, and 16

While executing the pg_autoctl do service command facing below error but in documentation of 2.0 version the command exists

[sudo] password for postgres:
