I've just Installed Debian Testing.I want to apt pin Squeeze and Sid(testing and unstable). I want to have testing along with packages from unstable also installed with almost equal priority hopefully not breaking the system. few years back,I tried running unstable and experimental apt-pinned and it was such a mess with daily huge updates. I don't want such a mess. My Plan is to Apt Pinn: Debian Squeeze,Debian Squeeze-proposed-updates given maximum priority Debian Sid/Unstable given slightly less Priority. There is a testing-proposed-updates repository also with Debian Squeeze. Checked your(falko) How to and Below is How My /etc/apt/preferences File Looks like: Code: Package: * Pin: release a=testing Pin-Priority: 700 Package: * Pin: release a=testing-proposed-updates Pin-Priority: 700 Package: * Pin: release a=unstable Pin-Priority: 650 And here ,the Other Files: /etc/apt/apt.conf: Code: APT::Cache-Limit "100000000"; APT::Default-Release "testing"; and /etc/apt/sources.list : Code: # Testing deb http://ftp.debian.org/debian/ testing main contrib non-free deb-src http://ftp.debian.org/debian/ testing main contrib non-free #Testing Security Updates deb http://security.debian.org/ testing/updates main deb-src http://security.debian.org/ testing/updates main #Testing Proposed Updates deb http://ftp.debian.org/debian/ testing-proposed-updates main contrib non-free deb-src http://ftp.debian.org/debian/ testing-proposed-updates main contrib non-free # Marillat For info visit http://www.debian-multimedia.org deb http://www.debian-multimedia.org testing main non-free #deb-src http://www.debian-multimedia.org testing main #Unstable deb http://ftp.debian.org/debian/ unstable main contrib non-free deb-src http://ftp.debian.org/debian/ unstable main contrib non-free #Unstable Kirya deb http://packages.kirya.net/debian/ sid main contrib non-free deb-src http://packages.kirya.net/debian/ sid main contrib non-free Is This OK? Thanks
Solved Forgot to Update the Post. apt-cache policy shows everything as of now was pulled from testing(Squeeze) repository I've below /etc/apt/apt.conf file: Code: APT::Cache-Limit "100000000"; APT::Default-Release "testing"; and /etc/apt/preferences file: Code: Package: * Pin: release a=testing Pin-Priority: 900 Package: * Pin: release a=unstable Pin-Priority: 300 Package: * Pin: release o=Debian Pin-Priority: -1
