bug#35550: Installer: wpa_supplicant fails to start

["Ludovic Courtès" <ludo@gnu.org>]

Hello,

Ricardo and sirgazil reported on IRC that the ‘wpa-supplicant’ would
(sometimes?) fail to start for the in the installation image on their
laptop.

As a result the ‘networking’ service (Connman) would not start either;
thus, the installer would report that it failed to establish Internet
access, and would just stop there.

Sirgazil posted /var/log/messages, which shows this:
