Do you have any apparmor messages in the dmesg output of that machine where chrony is failing to start?
After the first reboot, if you issue a sudo systemctl restart chrony, does it work? Or same problem? You said it's a desktop, how is the network brought up there? Is it only available after the user logs in? You also said at some point it was a VM, is that just for testing and debugging this problem, and you have a "real" desktop elsewhere, or is your real use case that VM? -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to chrony in Ubuntu. https://bugs.launchpad.net/bugs/1779966 Title: chrony fails to start, nm-dispatcher hook causes high CPU load To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chrony/+bug/1779966/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
