This bug was fixed in the package chrony - 3.3-2ubuntu1

---------------
chrony (3.3-2ubuntu1) cosmic; urgency=medium

  * Merge with Debian unstable (LP: #1771061). Remaining changes:
    - d/chrony.conf: use ubuntu ntp pool and server (LP 1744664)
    - Set -x as default if unable to set time (e.g. in containers) (LP: 1589780)
      Chrony is a single service which acts as both NTP client (i.e. syncing the
      local clock) and NTP server (i.e. providing NTP services to the network),
      and that is both desired and expected in the vast majority of cases.
      But in containers syncing the local clock is usually impossible, but this
      shall not break the providing of NTP services to the network.
      To some extent this makes chrony's default config more similar to 'ntpd',
      which complained in syslog but still provided NTP server service in those
      cases.
      - debian/chrony.service: allow the service to run without CAP_SYS_TIME
      - debian/control: add new dependency libcap2-bin for capsh (usually
        installed anyway, but make them explicit to be sure).
      - debian/chrony.default: new option SYNC_IN_CONTAINER to not fall back
        (Default off).
      - debian/chronyd-starter.sh: wrapper to handle special cases in containers
        and if CAP_SYS_TIME is missing. Effectively allows to run NTP server in
        containers on a default installation and avoid failing to sync time (or
        if allowed to sync, avoid multiple containers to fight over it by
        accident).
      - debian/install: make chronyd-starter.sh available on install.
      - debian/docs, debian/README.container: provide documentation about the
        handling of this case.
    - d/postrm: re-establish systemd-timesyncd on removal (LP: 1764357)
    - Notify chrony to update sources in response to systemd-networkd
      events (LP: 1718227)
      - d/links: link dispatcher script to networkd-dispatcher events routable
        and off
      - d/control: set Recommends to networkd-dispatcher
      - d/p/lp-1718227-nm-dispatcher-for-networkd.patch
  * Dropped changes
    - debian/usr.sbin.chronyd: ensure RTC/GPS usage isn't blocked by apparmor
      (LP: 1751241) (in Debian now)
    - debian/usr.sbin.chronyd: add cap net_admin for hwtimestamp (LP: 1761327)
      (in Debian now)
    - d/p/lp1589780-sys_linux-don-t-keep-CAP_SYS_TIME-with-x-option.patch:
      When dropping the root privileges, don't try to keep the CAP_SYS_TIME
      capability if the -x option was enabled. This allows chronyd to be
      started without the capability (e.g. in containers) and also drop the
      root privileges (This is upstream now).
    - d/p/lp-1718227-ignore-non-up-down-events-in-nm-dispatcher.patch (This is
      upstream now).
    - d/control: switch to nss instead of tomcrypt (Debian switched to nettle
      which is in main, so we can drop this)
