Package: apt-cudf Version: 4.2-2 Severity: normal Dear maintainer,
We use sbuild wit the cudf resolver on the build daemons, with the following optimization criteria: $aspcud_criteria = '-removed,-changed,-new,-count(solution,APT-Release:=/experimental/)'; Unfortunately this doesn't work when the available packages are newer than the one installed in the chroots. See for example this build log [1], where the binary packages from util-linux are installed in the chroot in version 2.28-4 while 2.28-5 is available in the package file: | Installing build dependencies | Reading package lists... | Building dependency tree... | Reading state information... | Execute external solver... | 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: | e2fsprogs : PreDepends: libuuid1 (>= 2.16) but it is not going to be installed | libblkid1 : Depends: libuuid1 (>= 2.16) but it is not going to be installed | libcryptsetup4 : Depends: libuuid1 (>= 2.16) but it is not going to be installed | libdapserver7v5 : Depends: libuuid1 (>= 2.16) but it is not going to be installed | libfdisk1 : Depends: libuuid1 (>= 2.16) but it is not going to be installed | libsm6 : Depends: libuuid1 (>= 2.16) but it is not going to be installed | util-linux : PreDepends: libuuid1 (>= 2.16) but it is not going to be installed | uuid-dev : Depends: libuuid1 (= 2.28-5) but it is not going to be installed | E: Broken packages | apt-get failed. | Package installation failed | Not removing build depends: cloned chroot in use This can also be reproduced using the following command: | apt-get --solver aspcud -o 'APT::Solver::Strict-Pinning=false' -o 'APT::Solver::aspcud::Preferences=-removed,-changed,-new,-count(solution,APT-Release:=/experimental/)' build-dep qgis After upgrading libuuid1 from version 2.28-4 to 2.28-5 in the chroot, the build-dep installation is then successful. I wouldn't be surprised the bug involves pre-depends.
