Package: apt-cudf Version: 5.0.1-8 Severity: normal Hi,
This bug has arisen after I started looking at why pdl 1:2.018-1~exp1 has been failing to install its dependencies in experimental. https://buildd.debian.org/status/package.php?p=pdl&suite=experimental The failures only happen when the aspcud solver is used. When the normal APT solver is used, everything works fine. The error in pdl seems to revolve around the versioned provides of perl-base which currently confuse apt-cudf because perl-base in sid does NOT use versioned provides, but perl-base in experimental does. I've attached a simplified test case which illustrates this. When running apt-cudf on it I get this invalid solution: $ apt-cudf --solver=aspcud test.edsp Install: 101 Package: banana Version: 1 Architecture: amd64 This is wrong because the cantelope dependency has not been satisfied. Either cantelope needs to be installed, or eggplant needs to be upgraded. ====== The problem seems to be that banana has a generated CUDF dependency on cantelope like this: > package: banana%3aamd64 > version: 2 > depends: cantelope%3aamd64 >= 3 | --virtual-cantelope%3aamd64 = 2147483647 | > --virtual-cantelope%3aamd64 >= 3 But this gets satisfied by the OLD (already installed) eggplant which has an unversioned provides: > package: eggplant%3aamd64 > version: 2 > conflicts: eggplant%3aamd64 , eggplant > provides: eggplant , --virtual-cantelope%3aamd64 = 2147483646 Thanks, James
