A execução de 'ntpd -q -g' para definir a hora em Raspberry Pi nunca é concluída

1

No meu Raspberry Pi que está em funcionamento há cerca de 4 ou 5 anos, tenho uma tarefa cron executando a cada hora que define a hora. Eu conheço experiência de forma que o meu Pi tem uma tendência a variar um pouco o tempo dele enquanto ele está rodando, então eu encontrei um script que o redefine. Tem funcionado perfeitamente por muito tempo e de repente não funciona mais. O ntp.conf está aqui:

# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help

driftfile /var/lib/ntp/ntp.drift


# Enable this if you want statistics to be logged.
#statsdir /var/log/ntpstats/

statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable


# You do need to talk to an NTP server or two (or three).
#server ntp.your-provider.example

# pool.ntp.org maps to about 1000 low-stratum NTP servers.  Your server will
# pick a different set every time it starts up.  Please consider joining the
# pool: <http://www.pool.ntp.org/join.html>
server 0.uk.pool.ntp.org iburst
server 1.uk.pool.ntp.org iburst
server 2.uk.pool.ntp.org iburst
server 3.uk.pool.ntp.org iburst


# Access control configuration; see /usr/share/doc/ntp-doc/html/accopt.html for
# details.  The web page <http://support.ntp.org/bin/view/Support/AccessRestrictions>
# might also be helpful.
#
# Note that "restrict" applies to both servers and clients, so a configuration
# that might be intended to block requests from certain clients could also end
# up blocking replies from your own upstream servers.

# By default, exchange time with everybody, but don't allow configuration.
restrict -4 default kod notrap nomodify nopeer noquery
restrict -6 default kod notrap nomodify nopeer noquery

# Local users may interrogate the ntp server more closely.
#restrict 127.0.0.1
#restrict ::1

# Clients from this (example!) subnet have unlimited access, but only if
# cryptographically authenticated.
#restrict 192.168.123.0 mask 255.255.255.0 notrust


# If you want to provide time to your local subnet, change the next line.
# (Again, the address is an example only.)
#broadcast 192.168.123.255

# If you want to listen to time broadcasts on your local subnet, de-comment the
# next lines.  Please do this only if you trust everybody on the network!
#disable auth
#broadcastclient

A tarefa do cron que tenho executa este script:

#! /bin/bash
/etc/init.d/ntp stop
ntpd -q -g
/etc/init.d/ntp start

Agora, quando isso executa o comando ntp -q -g, recebo este conjunto de mensagens e ele nunca sai:

Alguma ideia? Se eu quiser que o relógio Pi sincronize com um servidor de horário, qual é a maneira mais simples de fazê-lo?
