Leapsecond file expired

We are receiving warnings from the ntp (ntpsec) service for days know about a expired leap-second file:

Jun 28 01:19:43 ntpd[1514]: CLOCK: leapsecond file ('/usr/share/zoneinfo/leap-seconds.list'): will expire in less than one day
Jun 28 09:19:43 ntpd[1514]: CLOCK: leapsecond file ('/usr/share/zoneinfo/leap-seconds.list'): expired less than 1 day ago
Jun 29 09:19:43 ntpd[1514]: CLOCK: leapsecond file ('/usr/share/zoneinfo/leap-seconds.list'): expired less than 2 days ago

Jun 30 08:47:57 ntpd[1646858]: CLOCK: leapsecond file ('/usr/share/zoneinfo/leap-seconds.list'): expird less than 3 days ago

Looking at the file, the expire date is set to 28.06.2025:

❯ grep "File expires" /usr/share/zoneinfo/leap-seconds.list
#       File expires on 28 June 2025

Looking at another Debian 12 (non Univention) machine, the expiry date is set to 28 December 2025.

So, somewhere the leap-seconds.list won’t get updated? AFAIK it’s getting pulled from the tzdata package?

Does anybody else have this issue? or is this a misconfiguration from our part?
