Package: apt Version: 1.0.10.2 Severity: normal Hi,
The EDSP spec says that the Install field containing the installation request does not contain version numbers. Instead, packages can contain the APT-Candidate field set to Yes to denote that this version should be selected for installation. Nevertheless, when I do: apt-get --simulate install --solver dump -o APT::Solver::Strict-Pinning=false ghc=7.10.2-2 or apt-get --simulate install --solver dump -o APT::Solver::Strict-Pinning=false ghc/experimental then the resulting /tmp/dump.edsp does not contain any such field and thus the solver is not told which version of ghc to install. This is even though the second command tells me: Selected version '7.10.2-2' (Debian:experimental [amd64]) for 'ghc' Please make it so that specifying ghc=7.10.2-2 or ghc/experimental on the apt command line both mark the right package stanza in the EDSP output with APT-Candidate:Yes. I found this bug through bug #795827 but did not manage to find a followup bug that described this problem. CC-ing Ralf as the submitter of that bug and as the maintainer of apt-cudf in Debian. Thanks! cheers, josch
