Public bug reported:

Scheduled-For: ubuntu-25.11
Ubuntu: 4.7-1ubuntu1
Debian Unstable: 4.8-1

A new release of chrony is available for merging from Debian Unstable.

If it turns out this needs a sync rather than a merge, please change the
tagging from ['needs-merge', 'upgrade-software-version'] to ['needs-
sync', 'upgrade-software-version'], and (optionally) update the title as
desired.

If this merge pulls in a new upstream version, also consider adding an
entry to the r-series Release Notes:
https://discourse.ubuntu.com/c/project/release/38

### New Debian Changes ###

chrony (4.8-1) unstable; urgency=medium

  * Import upstream version 4.8:
    - Please see /usr/share/doc/chrony/NEWS.gz for the release notes.

  * Merge branch 'debian/unstable' into debian/latest.

  * Upload to unstable.

  * debian/chrony.sysusers:
    - Install a sysusers.d file to create the _chrony system user/group.

  * debian/control:
    - Build-depend on dh-sequence-installsysusers.
    - Drop unused adduser dependency.

  * debian/postinst:
    - Drop adduser invocation. The _chrony system user/group is now created
    using a sysusers.d fragment.
    - Allocate the _chrony system user/group before running dpkg-statoverride
    commands.

  * debian/postrm:
    - Don't delete the _chrony system user/group during purge.
    Deleting it is risky because sensitive files belonging to this uid might
    remain on the filesystem and could be recovered by another system user
    reusing the same uid.

  * debian/tests/upstream-simulation-test-suite:
    - Update clknetsim version.
    - Get clknetsim from Gitlab.

  * debian/watch:
    - Update to version 5.

chrony (4.8~pre1-1) experimental; urgency=medium

  * Import upstream version 4.8-pre1:
    - Please see /usr/share/doc/chrony/NEWS.gz for the release notes.

  * debian/control:
    - Drop 'Priority: optional'. dpkg sets it by default if omitted.
    - Drop 'Rules-Requires-Root: no'. dpkg sets it by default if omitted.

  * debian/copyright:
    - Add a few entries and update copyright year.

  * debian/test/upstream-simulation-test-suite:
    - Update clknetsim version.

chrony (4.7-3) unstable; urgency=medium

  * debian/patches/:
    - Add skip-flaky-007-cmdmon-system-test.patch. Upstream system test
    007-cmdmon fails intermittently. Skip it! (Closes: #1111222)

### Old Ubuntu Delta ###

chrony (4.7-1ubuntu1) questing; urgency=medium

  * Merge with Debian experimental. Remaining changes: (LP: #2110435)
    - 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
      + d/control: add new dependency libcap2-bin for capsh (usually
        installed anyway, but make them explicit to be sure).
      + d/chrony.default: new option SYNC_IN_CONTAINER to not fall
        back (Default off)
      + d/chronyd-starter.sh: wrapper to handle special cases in
        containers and if CAP_SYS_TIME is missing. Effectively allows
        running the NTP server in containers on a default installation
        and avoid failing to sync time (or if allowed to sync, avoid
        multiple containers fighting over it by accident).
      + d/install: Make chrony-starter.sh available on install.
      + d/docs, d/README.container: Provide documentation about the
        handling of this case.
    - d/rules, d/chrony.examples: Ship restricted service as an example
      not installed to the system for use.  (See LP #2051028)
    - d/chrony.conf: remove Debian NTP pool
    - Install Ubuntu NTP sources in
      /etc/chrony/sources.d/ubuntu-ntp-pools.sources, gated on a low priority
      (default yes) debconf question (LP #2048876):
      + d/templates: Add debconf question to customize installation of
        /etc/chrony/sources.d/ubuntu-ntp-pools.sources
      + d/install, d/ubuntu-ntp-pools.sources: Install ubuntu-ntp-pools.sources
        in /usr/share/chrony
      + d/control: add dependency on debconf
      + d/postinst: handle Ubuntu pools via debconf and ucf
      + d/postrm: handle Ubuntu pools via debconf and ucf
      + d/NEWS: Add information about default time sources moving out from
        chrony.conf to /etc/chrony/sources.d/ubuntu-ntp-pools.sources.
      + d/chrony.config: debconf script to handle Ubuntu pools
      + d/t/control, d/t/default-ubuntu-sources-behavior: new test to check the
        debconf behavior
    - Use Ubuntu NTS servers by default (LP #2084585):
      + d/conf.d/ubuntu-nts.conf: refer to the CA used to sign the NTS bootstrap
        server
      + d/nts-bootstrap-{,staging}-ubuntu.crt: CA certificate for the NTS
        bootstrap servers
      + d/install: install the NTS bootstrap CAs
      + d/ubuntu-ntp-pools.sources: use NTS by default
      + d/t/default-ubuntu-sources-behavior: update tests for NTS support
      + d/NEWS: add news entry about the NTS change
  * Drop Changes:
    - d/t/helper-functions: Do not fail if backup does not exist
      [Fixed in 4.7-1]
    - d/tests: Clean up after __no_system_clock_control()
      [Fixed in 4.7-1]
    - d/chrony.service: Do not run inside containers by default (LP 2111535)
      [Fixed in 4.7-1]
    - d/t/default-ubuntu-sources-behavior: Adopt to upstream container handling.
      [Squashed into "new test to check the debconf behavior"]
  * Add Changes:
    - d/chrony.service: Allow real chronyd to send READY=1 via sd_notify in
      place of the chronyd-starter.sh wrapper.
    - d/usr.sbin.chronyd: Grant access to NOTIFY_SOCKET in AppArmor profile.
    - d/chrony.conf: Document non-NTS sources from DHCP (LP: #2115565)
