EXCERPT for NTP issues:
NTP does not sync under certain circumstances. If this happens, please open a new thread on the VIRL CLN Community Forum.

Workaround: Restart NTPd using sudo systemctl restart ntp, check with ntpq -p.
Sometimes, it was sometimes necessary to kill the nptd process manually:

sudo systemctl stop
ntp killall ntpd
sudo systemctl start

VALIDATION checklist:
- images are upgraded
