Hey,
Thank you for your reply Sven, and sorry for the belated response. Here is my setup now: sources.list ``` # stable deb https://deb.debian.org/debian/ bookworm main contrib non-free-firmware non-free deb-src https://deb.debian.org/debian/ bookworm main contrib non-free-firmware non-free deb https://security.debian.org/debian-security/ bookworm-security main contrib non-free-firmware non-free deb-src https://security.debian.org/debian-security/ bookworm-security main contrib non-free-firmware non-free deb https://deb.debian.org/debian/ bookworm-updates main contrib non-free-firmware non-free deb-src https://deb.debian.org/debian/ bookworm-updates main contrib non-free-firmware non-free deb http://deb.debian.org/debian/ bookworm-backports main contrib non-free-firmware non-free deb-src http://deb.debian.org/debian/ bookworm-backports main contrib non-free-firmware non-free # testing deb https://deb.debian.org/debian/ trixie main contrib non-free-firmware non-free deb-src https://deb.debian.org/debian/ trixie main contrib non-free-firmware non-free deb https://security.debian.org/debian-security/ trixie-security main contrib non-free-firmware non-free deb-src https://security.debian.org/debian-security/ trixie-security main contrib non-free-firmware non-free deb https://deb.debian.org/debian/ trixie-updates main contrib non-free-firmware non-free deb-src https://deb.debian.org/debian/ trixie-updates main contrib non-free-firmware non-free deb http://deb.debian.org/debian/ trixie-backports main contrib non-free-firmware non-free deb-src http://deb.debian.org/debian/ trixie-backports main contrib non-free-firmware non-free # unstable deb https://deb.debian.org/debian/ sid main contrib non-free-firmware non-free deb-src https://deb.debian.org/debian/ sid main contrib non-free-firmware non-free # experimental deb https://deb.debian.org/debian/ experimental main contrib non-free-firmware non-free deb-src https://deb.debian.org/debian/ experimental main contrib non-free-firmware non-free ``` (let him who is without bluetooth be the first to judge me for non-free) sources.pref ``` # stable Package: * Pin: release o=Debian Backports, n=bookworm-backports Pin-Priority: 502 Package: * Pin: release o=Debian, n=bookworm* Pin-Priority: 501 # testing Package: * Pin: release o=Debian, n=trixie* Pin-Priority: 102 # unstable Package: * Pin: release o=Debian, n=sid* Pin-Priority: 1 Package: * Pin: release o=Debian, a=experimental Pin-Priority: -1 ``` This seems to work exactly as I want, but I feel like my preferences setup is not ideal. Repeating "Debian" every time, the wildcards, the codenames (I already have them "locked in" via sources.list). Any advice on how to clean it up nicely? Also, do I need to make special pin-priority accommodations for the security releases? Thanks
