Build command 'cd libjpeg9-9a && dpkg-buildpackage -b -uc' failed. As you can see from above, dpkg-checkbuilddeps and apt-get build-dep disagree. This might be because unstable currently carries two automake packages in different versions: Package: automake Source: automake-1.14 Version: 1:1.14.1-4 Architecture: all Provides: automake-1.14, automaken Depends: autoconf (>= 2.65), autotools-dev (>= 20020320.1) Conflicts: automake (<< 1:1.4-p5-1), automake1.10-doc, automake1.5 (<< 1.5-2), automake1.6 (<< 1.6.1-4) Multi-Arch: foreign Package: automake Source: automake-1.15 Version: 1:1.15-3 Architecture: all Provides: automake-1.15, automaken Depends: autoconf (>= 2.65), autotools-dev (>= 20020320.1) Suggests: autoconf-doc, gnu-standards Conflicts: automake (<< 1:1.4-p5-1), automake1.10-doc, automake1.5 (<< 1.5-2), automake1.6 (<< 1.6.1-4) Multi-Arch: foreign Steps to reproduce for apt-get install: $ cat > control << END > Package: dummy > Depends: automake-1.14 > END $ equivs-build control $ apt-get install ./dummy_1.0_all.deb The following packages have unmet dependencies: dummy : Depends: automake-1.14 E: Unable to correct problems, you have held broken packages. It seems automake (= 1:1.14.1-4) provides automake-1.14 while automake (= 1:1.15-3) provides automake-1.15. It might be that somehow apt sees that "automake" provides automake-1.14 but does not store which version of "automake" provides it and just either installs the newest one in the "apt-get build-dep" case or only picks the newest one as a candidate and then fails to satisfy the dependency because that version doesn't provide automake-1.14. Ideally, apt should see that there are different versions of the same package with the same pin value but different provides and pick the one that satisfies the dependency even if it's of a lower version. After all, both packages are part of the same suite. Though with apt's behaviour of selecting only the highest version as the candidate I can see why this will not be happening and maybe instead automake should change how they do their virtual packages. But then again, on what grounds should automake change their provides? Only because of an apt limitation? As far as I can see they are policy compliant and other resolvers like dose3 or aspcud will happily find a solution. The clear policy violation here is the "apt-get build-dep" problem because apt installs a package that is not satisfying the build dependency at hand. This has to be fixed. At least just fail in the same way as during binary package installation. What do you think? cheers, josch
