It's not missing but it's uninstallable in sid together with the other build dependencies, specifically libgsl-dev. Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libgsl-dev : Depends: libgsl23 (= 2.4+dfsg-4) but it is not going to be installed Depends: libgslcblas0 (= 2.4+dfsg-4) but it is not going to be installed E: Unable to correct problems, you have held broken packages. This is due to gsl breakage/uncoordinated transition, see #869778 . -- Niko Tyni nt...@debain.org
