Message printing after I apt-get install or needrestart about services, containers, user sessions and VMs

Question

I've just put Ubuntu 22.04 on my server, and when I execute apt-get install x(where x a package I want to download) or needrestart, I get this message that I haven't found an explanation for.

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No user sessions are running outdated binaries.

No VM guests are running outdated hypervisor (qemu) binaries on this host.

Also, after the last line (No VM guests are running outdated hypervisor (qemu) binaries on this host.), it has some delay before I can type another command.

Any help as to what it means and why it appears would be appreciated

It tells you what needs to be restarted for the updates to be effective. In this case, nothing.

The behavior depends on the setting $nrconf{restart} in /etc/needrestart/needrestart.conf

i: prompt interactively for restarts (default value)
a: restart automatically
l: list needed restarts

Oh, so it's a heads-up in case a service that needs restarting got omitted for some reason? – Costas M Sep 19 '22 at 09:50
Yes, exactly that. – Gerald Schneider Sep 19 '22 at 09:50
Great, thank you! Do you perhaps have any idea as to how a similar message would appear, with the difference that it would ask for something to be restarted? – Costas M Sep 19 '22 at 09:51
