As of today many Travis users are seeing this error: The following packages have unmet dependencies: libmagick++-dev : Depends: libmagickcore-dev (= 8:6.7.7.10-6ubuntu3.9) but it is not going to be installed Depends: libmagickwand-dev (= 8:6.7.7.10-6ubuntu3.9) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
The problem is that a few hours ago a version of libpng1.6 was published to c2d4u3.5 which is not compatible with the version of imagemagick in trusty. Becuase libmagick++ is installed by default on Travis, this breaks almost all installations. I think it's best to only publish R packages in c2d4u, not system libs. _______________________________________________ R-SIG-Debian mailing list R-SIG-Debian@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-debian
