Under Ubuntu 24.04, installing canonical-certification-server requires user interaction

Bug Description

When installing canonical-certification-server in Ubuntu 24.04, apt presents a "Configuring iperf3" text-mode dialog:

│ Choose this option if Iperf3 should start automatically as a daemon, now  │ 
│ and at boot time.                                                         │ 
│                                                                           │ 
│ Start Iperf3 as a daemon automatically?                                   │ 
│                                                                           │ 
│                    <Yes>                       <No> 

This is OK if it's happening at the console; but if it's being installed automatically (as part of a Testflinger deployment, say), it leaves the package unconfigured, which then prevents further APT actions until the issue is resolved.

I'm not sure if this is really best handled as a Checkbox bug, or should be dealt with by adapting other projects.

To Reproduce

1. Install Ubuntu 24.04
2. sudo add-apt-repository pp:checkbox-dev/stable
3. sudo apt install canonical-certification-server

Environment

• Ubuntu 24.04.
• Tested on two systems -- notso (in DRN) and brennan (one of my own computers)
• APT packaging

I've verified that installing iperf3 alone, before installing c-c-s, does the same thing.

As a workaround (noted in email), you can try this:

sudo DEBIAN_FRONTEND=noninteractive apt install iperf3

which should squash the user interactivity. (Note, you may need to do this with apt-get, I'm not sure if apt will listen to that setting or not.
