The location source '/var/lib/dpkg/status' indicates that that version of the package is found in the list of installed packages on your machine, rather than in a package list from an upstream repository. (For most packages, you will see _two_ location source lines under the installed version: one from /var/lib/dpkg/status, and the other from a configured repository.) Since the list of installed packages on your machine doesn't include an indication of where to obtain the .deb file for installation, apt-get can't find the file it needs to carry out the install, so it can't proceed. That said, the .deb file in question is probably located on the machine where the package _is_ installed, under /var/cache/apt/archives/ - but there will almost certainly be a _lot_ of .deb files there, and sorting through them may be confusing. I would recommend that you either proceed with downgrading all of the libav* packages (which includes libswsample*) - probably on both machines - or figure out what repository you got them from, re-enable it, and see how you can proceed from there. In the latter vein, you might find it worthwhile to check /etc/apt/sources.list and see whether you have any commented-out repositories. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.

So > I will just have to purge libswresample2, and libavutil55 (>= 10:3.1.2) Actually, it looks like libswresample2 has the same problem: the installed version has a higher epoch but lower actual version. My best guess is that at some point, you installed some package from a different repository, which depended on these higher-epoch package versions, and thus got them upgraded without upgrading the rest of your libav* package ecosystem. I would just add libswresample2 to your explicit-version install command, and see what result you get. It may give further unmet-dependencies errors; if you pursue the cascade far enough (I'd advise checking each new package with 'apt-cache policy' to see available versions before proceeding), you may be able to identify the package(s) which depend or depended on the higher-epoch libav* packages to begin with. (Purging the libav* packages will probably result in trying to uninstall various packages which depend on them, possibly including quite a few things you may actually want. Although you could always do that and reinstall the appropriate packages afterwards, "down"grading is almost certainly the superior solution.) -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
