Package: apt-cudf Version: 5.0.1-9+b3 Severity: normal It is my understanding that if plain apt can find a solution to install a package, running apt with the aspcud solver should also be able to find a solution. However, when I try to add "+sum(solution,apt-pin)" to the set of solver preferences, I get an "Execute external solver... Error!". After discussion on IRC (#d-devel) we decided a report against apt-cudf would be in order. Please find the logging of what I tried copied below.
