a simple 'aptitude -u' does the job for me :-( The core file I get inside the chroot is actually from the qemu binary on the host, perhaps this backtrace helps: Reading symbols from /usr/bin/qemu-aarch64-static...Reading symbols from /usr/lib/debug/.build-id/30/efd3930fb9519b21470b113679376f2ffbb41a.debug...done. done. warning: core file may not match specified executable file.
