This bug was fixed in the package chrony - 3.4-1ubuntu1

---------------
chrony (3.4-1ubuntu1) disco; urgency=medium

  * Merge with Debian unstable (LP: #1802886). 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
  * Dropped Changes (upstream):
    - d/p/lp-1718227-nm-dispatcher-for-networkd.patch
    - d/p/lp-1787366-fall-back-to-urandom.patch: avoid hangs when starting
      the service on newer kernels by falling back to urandom. (LP: 1787366)
  * Added Changes:
    - d/postrm: respect policy-rc.d when restoring systemd-timesyncd
      (LP: #1771994)

chrony (3.4-1) unstable; urgency=medium

  * Import upstream version 3.4:
    - Please see /usr/share/doc/chrony/NEWS.gz for the release notes.

  * debian/chrony.service:
    - Conflict with ntpsec.service.

  * debian/copyright:
    - Update copyright years.

  * debian/patches/*:
    - Remove fix-samplefilt-unit-test-to-work-with-low-precision-clock.patch,
    fixed upstream.

chrony (3.4~pre1-2) experimental; urgency=medium

  * debian/patches/*:
    - Cherry-pick upstream patch to fix samplefilt unit test to work with
    low-precision clocks. This should prevent chrony from failing to build
    from source on HPPA and Alpha.

chrony (3.4~pre1-1) experimental; urgency=medium

  * Import upstream version 3.4-pre1:
    - Please see /usr/share/doc/chrony/NEWS.gz for the release notes.

  * debian/:
    - Add “.gitlab-ci.yml” file to use GitLab Continuous Integration.

  * debian/chrony.if-{post-down,up}:
    - Use the new “onoffline” command to tell chronyd to switch all sources to
    the online or offline status according to the current network configuration.

  * debian/chrony.ppp.ip-{down,up}:
    - As for ifupdown scripts, use the “onoffline” command.

  * debian/control:
    - Bump standard-version to 4.2.1 (no changes required).

  * debian/patches/*:
    - Remove fall-back-to-urandom.patch. Applied in this prerelease.

  * debian/post{inst,rm}:
    - Use “command -v” instead of “which” to enhance portability.

chrony (3.3-3) unstable; urgency=medium

  * debian/:
    - Normalize packaging with “wrap-and-sort -ab”.

  * debian/control:
    - Bump standard-version to 4.2.0:
        ↳ Install upstream release notes as “/usr/share/doc/chrony/NEWS.gz”.
          Installing these as “/usr/share/doc/package/changelog.gz” is now
          deprecated.

  * debian/patches/:
    - Cherry-pick upstream patch to avoid hangs when starting
    chronyd on newer kernels by falling back to urandom.
    Thanks to Gustavo Scalet <email address hidden> for the report and
    the initial patch. (LP: #1787366, Closes: #906276)

  * debian/upstream/metadata:
    - Add DEP12 upstream metadata file.
