Hi,  
in the headless package there is a handy little script which is able to perform an easy upgrade to the most recent version. It relies on jq to extract the current upgrade URL but this means that jq should be installed 😃  
A little proposal for a preliminary check

```auto
#!/bin/bash

# Check if jq is available
if ! command -v jq &>/dev/null
then
        echo "Please install jq first"
        exit
fi

# Release channel is passed as first argument.
...

```

Have a nice day  
Gaetano
