Beware that Testing is entering the most volatile time in its lifecycle. The floodgates are open now. Updates are flowing. Life in Testing is getting interesting again. > here is my current /etc/apt/sources.list: Sure. > Is this what it should be changed to:? Yes. That would be okay. I suggest using the named release candidate "stretch" rather than "testing". That way when stretch releases and becomes the new Stable release at that time your system would not automatically be pulled forward. That gives you time to read the release notes and to react to required actions needed before the next upgrade. > (In the past, i have tried that, and it screwed up my installation.

Instead it is the nature of using the release candidate Testing or Unstable versions. When using those beta release tracks you are the beta tester. Sometimes there are problems. It isn't a released track. There is no guarantee that you won't have problems with it. Historically there have been many accidents and incidents that cause problem for both Unstable and Testing. Users of them are participating in the making of the sausage there. If you want a trouble free release track that is the Stable release. Jessie is now the new Stable release. Bob
