If you turn on DEBIAN_FRONTEND=noninteractive needrestart does still output this "Scanning process" progress bar:

Running kernel seems to be up-to-date.

No services need to be restarted.

No containers need to be restarted.

No user sessions are running outdated binaries.
Exit status: 0

In case, needrestart or the apt-get upgrade hook to run needrestart is started within a script or remote execution job, you would see the output as above. Wouldn't it be better to prevent the progress bar? Is this somehow already implemented with a special flag or environment var you need to set?

needrestart only prints the progress bar if stderr is a terminal

Are you observing this issue in some automation implementation lacking a real terminal implementation?
