Updated dns-root-data packages have been released for both Debian GNU/Linux 9 (Stretch) and 10 (Buster) Extended LTS:

ELA-1500-1 dns-root-data DNSSEC trust anchors update

ELA-1500-1 dns-root-data DNSSEC trust anchors update

Package : dns-root-data

Version : 2024071801~deb9u1 (stretch), 2024071801~deb10u1 (buster)

The dns-root-data package contains DNS root zone data as published by
IANA to be used as initial source by DNS software. This release adds
the DNSKEY record for the KSK-2024 trust anchor. This new key is
planned for use starting October 2026, and the previous one (KSK-2017)
should be revoked January 2027, leaving time to propagate the new
trust anchor, or roll to it sooner in case of emergency.
