Hi Andreas,

during a test with piuparts I noticed your package prompts the user
badly. Prompting in maintainer scripts must be done by communicating
through a program such as debconf which conforms to the Debian
Configuration Management Specification, version 2 or higher.
the Debian Policy does not apply - the observed bug is within the
upstream perl core.
A new installation works fine, updates are problematic.
The piuparts test is killed after exceeding its runtime.
Right now I accidently noticed this in a window where piuparts-slave is
running:
12:42:06 Testing package testing2sid/main/needrestart 1.2-4
Scanning processes...
Scanning candidates...
SET needrestart/ui-query_pkgs sysv init
I think this is triggered by a division by zero in the same code path as
in #767370. This could be triggered if no kernel images were found or no
process being a restart candidates. Both conditions occure rarely in the
wild. Therefore the severity of this issue should be not higher than normal.
You may not access /dev/tty for prompting (or whatever) ...
use debconf *properly*.
/dev/tty is not used for prompting while using needrestart's debconf
frontend - but the bug broke the debconf pipe.
needrestart does intentionally not use debconf's progressbar widget
since it disrupts the tty's scrollback buffer (see also #748758).
HTH,
Thomas
