As of 10/1/24 3:52 UTC time, Trixie/Debian testing does not have a fix for the severe cupsd security vulnerability that was recently announced, despite Debian Stable and Unstable having a fix.

Debian Testing is intended for testing, and not really for production usage.

So the way Debian Unstable/Testing works is that packages go into unstable/ for a bit, and then are migrated into testing/trixie.

Issues preventing migration: ∙ ∙ Too young, only 3 of 5 days old

Basically, security vulnerabilities are not really a priority in testing, and everything waits for a bit before it updates.

I recently saw some people recommending Trixie for a "debian but not as unstable as sid and newer packages than stable", which is a pretty bad idea. Trixie/testing is not really intended for production use.

If you want newer, but still stable packages from the same repositories, then I recommend (not an exhaustive list, of course).:

• Opensuse Leap (Tumbleweed works too but secure boot was borked when I used it)
• Fedora

If you are willing to mix and match sources for packages:

• Flatpaks
• distrobox — run other distros in docker/podman containers and use apps through those
• Nix

Can get you newer packages on a more stable distros safely.
