Comment 17 for bug 2003756

I'm changing my opinion here.

I feel like this is indeed a problem with how init-system-helpers (more specifically, deb-systemd-invoke) warns users about errors. Since it uses "--quiet" when invoking systemctl, I believe it needs to be a bit more verbose to explain what happened.

What's interesting that I can't reproduce the apt failure. For example, "apt install proftpd" will warn me about deb-systemd-invoke, but the command will finish successfully. ISTR having seen this behaviour before, but I don't remember my conclusion at the time.

Anyway, this needs to be forwarded to Debian. I don't believe Ubuntu should diverge from Debian in this case.
