The difference between the commands can be explained: 'install' (and dist-upgrade) can do everything they want to, 'apt upgrade' can install new and upgrade old packages but not remove them and 'apt-get upgrade' can only upgrade packages, so different solutions wouldn't be a problem. That 'apt upgrade' is erroring out like that is one through as that isn't supposed to happen… And idealy the three wouldn't grossly disagree, but that just as a bonus… Can you attach your /var/lib/dpkg/status file (preferable compressed) ? [I think you know, but the usual disclaimer ramble anyhow: The file contains information about ALL packages you have installed and in what version. In case you don't want or can't expose these details to the public, you can sent it to me privately, if that is acceptable for you] Keeping the directory content of /var/lib/apt/lists someplace save might come in handy, too, but please just back it up somewhere as the resulting file would be too large and is usually not needed, if I can get hold of the Packages files any other way. > libghc-data-lens-dev : Depends: libghc-comonad-dev-4.2.5-ae1b1 but it is not installable > Depends: libghc-semigroupoids-dev-4.2-68274 but it is not installable Looking at the package names here makes me believe some unofficial/ staging repository is involved through. Is that one public? There are a bunch of debug flags we could try, but with ~300 packages involved that is usually not too much fun to look at via mail… Why solver comes to this solution: -o Debug::pkgDepCache::AutoInstall=1 -o Debug::pkgDepCache::Marker=1 -o Debug::pkgProblemResolver=1 How the execution shedule looks and why: -o Debug::pkgOrderList=1 (usually just noise through) -o Debug::pkgPackageManager=1 Best regards David Kalnischkies
