All droplets started generating email from cron.hourly

We have five or so droplets, all of which started generating an email from a failure of `/etc/cron.hourly/droplet-agent`. As far as I can tell, this just checks to see if it should be updated. The emails don't contain much interesting - just the output from the job if I run it on the command line:
```
/etc/cron.hourly/droplet-agent:
Waiting 596 seconds
Checking architecture support...OK
Preparing to check for update

Local Keyring:2.0.0
Local Version:1.2.12

No need to update
```
The question is - why did this start generating emails from the hourly run? Was the agent changed to produce output?

Our droplets are running debian 12.
