* What led up to the situation?
I noticed, since long time ago, that I was not anymore able to use
Apt-Pinning for installing packages from Stable and Testing
Releases.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Everytime I try to use "APT-Pinning", I do not get what I want.
Even if I try /testing or -t testing, or any Release other than
Experimental, I only get error or Experimental list of packages.
Finally, apt-cache policy only return Sid and Experimental
packages.
* What was the outcome of this action?
If I try
"apt-cache show -t testing linux-image-amd64"
OR
"apt-cache show linux-image-amd64/testing"
I get this with apt-get:
E: Release 'testing' for 'linux-image-amd64' was not found
E: No packages found
