Search the DistroWatch database for distributions using a particular package.If you are looking for a distribution with the latest kernel, select linux from the.Unstable.Wheezy.Jessie. Sid.Setup the apt sources for testingunstable repo.The first step is to add the testingunstable sources to your sources.The etcaptsources.Debian wheezy system looks something like this by default.Note down the url of the repository server http http.This repository server is a mirror that is located nearest to you.It shall be different in your sources.The same shall be used in the next steps.To add the testing and unstable sources you need to add something like this to your sources.Testing repository main, contrib and non free branches.Testing security updates repository.Unstable repo main, contrib and non free branches, no security updates here.The format isdeb lt respository servermirror lt repository name lt sub branches of the repo Instead of testingunstable the corresponding codenames jessie and sid can also be useddeb http http.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.Update the package cache.After adding the new repository and specify the pinning rules, update the package cache.Confirm the apt policy.We must ensure that the pinning configuration is correct and that the priorities are met correctly.Check the effective apt policy with the apt cache command apt cache policy apache.Installed none.Candidate 2.Version table.
