Subject: debconf: Readline Multiselect with one item: missing "none of the above"

Date: Thu, 09 Jan 2020 08:58:38 +0100

Package: debconf
Version: 1.5.73
Severity: normal

Dear Maintainer,

I routinely use the "Readline" frontend of debconf (in fact, my
settings indicate Dialog, but it falls back to Readline as I generally
do that inside an Emacs buffer).

When I do "apt dist-upgrade", if some services might have to be
restarted, the needrestart system prompts which service(s), if any, to
restart.  And sometimes I don't want to restart anything, so I select
"None of the above" (see Debconf/Element/Teletype/Multiselect.pm).

However today, I got this prompt below, and the choice "None of the
above" (or similar) is not possible, which looks like a bug: from the
perspective of a user who does not want any restart, it is unclear
what response should be given to this prompt.

    # apt dist-upgrade

    Running kernel seems to be up-to-date.

    Failed to check for processor microcode upgrades.

    Restarting services...
    Daemons using outdated libraries
    --------------------------------


      1. wpa_supplicant.service

    (Enter the items or ranges you want to select, separated by spaces.)

    Which services should be restarted?

It looks like giving an empty result does the correct thing, but for a
user who is accustomed to having the choice "None of the above", it is
disturbing.  Why is "None of the above" missing?

Thanks!

Best regards
Fabrice
