In my Buster system the situation is like this: ~$ apt-cache policy ntp ntp: Installed: (none) Candidate: 1:4.2.8p10+dfsg-6 Version table: 1:4.2.8p10+dfsg-6 500 500 http://ftp.tr.debian.org/debian testing/main amd64 Packages 1:4.2.8p10+dfsg-3+deb9u1 500 500 file:/sdb6/software/debian-9.2.1-amd64-DVD-1 stretch/main amd64 Packages Version 1:4.2.8p10+dfsg-3+deb9u1 is on the Stretch installation DVD (the bottom line) and the latest version in Buster repo is 1:4.2.8p10+dfsg-6 which do exist in my mirror ( http://ftp.tr.debian.org/debian/pool/main/n/ntp/ ) So, I think it seems like your update procedure didn't work for some reason, or you might have somehow pinned ntp package (you can check in Synaptic if ntp is "locked") to its original "deb9u1" version.
