Do some apt pinning Important After adding the testing and unstable repos, if you update the system then all available updates for all installed applications would be installed right away, leading the system to an unpredictable state. Therefore some rules have to be setup in order to restrict the package selection during regular updatesupgrades. This is done through apt pinning where we tell the apt system to use only the stable system as always, but we may select to install a particular package from the testing or unstable repository if we wish to. The apt pinning preferences can be configured into either of the following 2 files. Open either of the 2 locations create one if it does not exist and fill the following into the file. Package. Pin release astable. Pin Priority 7. Pin release atesting. Pin Priority 6. Pin release aunstable. Pin Priority 6. Mentioned earlier, stable will point to your current debian version, testing to the next, and unstable would be further away in future. Main thing to note is the priority. The stablecurrent version has been given the highest priority which means that for regular tasks apt get will install packages only from the current stable repository wheezy in this case.

Check the man page on apt preferences to learn more about them man 5 aptpreferences. Summary. Using the testingunstable repository with pinning is an easy way to get newer versions of packages, but it is not recommended. If done wrong, it can mess up the system by pulling packages from different branches that may not be compatible. A more recommended method to install updated packages is using the backports repository. It provides newer versions of selected packages from testingunstable repo, but compiled for the current stable version. So on debian wheezy you can use wheezy backports repository.
