Package: clock-setup Version: 0.155 Severity: important The user-provided NTP server address (in this case a 10(dot) IP address) provided during the initial Debian installation is not used by systemd-timesyncd in the running system. This has been noted on systems installed from Debian 11 NetInst images.
On systems with outbound network restrictions, this results in the clock never becoming synchronised, and log messages being reported in /var/log/syslog that requests to debian.pool.ntp.org servers are timing out. /etc/systemd/timesyncd.conf appears to be unchanged from the default packaged config file, with all lines commented out. A work around is to manually adjust the config after installation, however people unfamiliar with the bug (myself included until very recently) will likely not think to check, believing this has already been covered off during the Debian installation.
