kokkos is declared Multi-Arch: same, but fails to coinstall. The file /usr/bin/kokkos_launch_compiler is shared by kokkos version 5.2.2-2 as present in unstable with varying content. Please ensure that shared files have bit-identical content across architectures, move architecture-dependent files to architecture-dependent paths or remove the Multi-Arch: same field.
