I noticed today that one of my machines was still running openssh 1:9.2p1-2+deb12u1 rather than 1:9.2p1-2+deb12u2 even though it is supposed to do its unattended-upgrades, so I tried a manual upgrade and the result was still the same.
Only after apt install openssh-server/stable-security did the machine get the new version :-( The `sources.list` files says: deb http://security.debian.org/ stable-security main deb http://deb.debian.org/debian stable main and the `apt.conf` says: APT::Default-Release "stable"; Aptitude::CmdLine::Show-Deps "true"; APT::Periodic::Unattended-Upgrade "1"; Which I thought was the "normal" config (modulo the use of "stable" instead of "bookworm") where the `stable-security` would automatically take precedence when applicable. But it looks like the `stable-security` repository is just not used at all! What am I missing? Stefan
