On which version of Ubuntu did you experience this? Whilst the latest LTS (18.04) and non-LTS (19.04) versions have moved the ntp package to universe, they still ship with a fully working configuration. Here's an example from a stock install on an AWS EC2 instance running disco (19.04):
root@ip-172-31-7-27:~# grep ubuntu /etc/ntp.conf pool 0.ubuntu.pool.ntp.org iburst pool 1.ubuntu.pool.ntp.org iburst pool 2.ubuntu.pool.ntp.org iburst pool 3.ubuntu.pool.ntp.org iburst pool ntp.ubuntu.com root@ip-172-31-7-27:~# awk '/ubuntu/ {print $2}' /etc/ntp.conf | xargs -n1 host 0.ubuntu.pool.ntp.org has address 142.147.92.5 0.ubuntu.pool.ntp.org has address 12.71.198.242 0.ubuntu.pool.ntp.org has address 45.76.244.193 0.ubuntu.pool.ntp.org has address 104.168.88.15 1.ubuntu.pool.ntp.org has address 27.124.125.252 1.ubuntu.pool.ntp.org has address 129.250.35.250 1.ubuntu.pool.ntp.org has address 129.250.35.251 1.ubuntu.pool.ntp.org has address 13.55.50.68 2.ubuntu.pool.ntp.org has address 144.48.166.166 2.ubuntu.pool.ntp.org has address 203.7.149.149 2.ubuntu.pool.ntp.org has address 103.38.120.36 2.ubuntu.pool.ntp.org has address 103.76.40.123 2.ubuntu.pool.ntp.org has IPv6 address 2404:cc80:166::166 2.ubuntu.pool.ntp.org has IPv6 address 2407:f100:4:1::3 2.ubuntu.pool.ntp.org has IPv6 address 2a00:fd80:aaaa:ffff::eeee:ff2 2.ubuntu.pool.ntp.org has IPv6 address 2001:19f0:5801:1daa:5400:1ff:fe95:cf80 3.ubuntu.pool.ntp.org has address 220.158.215.20 3.ubuntu.pool.ntp.org has address 27.124.125.251 3.ubuntu.pool.ntp.org has address 103.38.120.36 3.ubuntu.pool.ntp.org has address 103.214.220.220 ntp.ubuntu.com has address 91.189.89.198 ntp.ubuntu.com has address 91.189.89.199 ntp.ubuntu.com has address 91.189.91.157 ntp.ubuntu.com has address 91.189.94.4 ntp.ubuntu.com has IPv6 address 2001:67c:1560:8003::c8 ntp.ubuntu.com has IPv6 address 2001:67c:1560:8003::c7 So for the stock configuration on released Ubuntu versions, this is factually incorrect. Can you provide any further details to explain how this is a problem? ** Changed in: ntp (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838146 Title: ntpd installation /etc/ntp.conf ~ hostnames listed do not exist on *.ntp.org To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/1838146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
