Hi, since some months, the default pbuilder installation (the default uses aptitude resolver) crashes when under a qemu environment. steps to reproduce pbuilder-dist sid arm64 create pbuilder-dist sid arm64 update crash. I tried to gdb but I didn't have to much luck in having a backtrace gdb aptitude qemu: Unsupported syscall: 278 GNU gdb (Debian 7.11.1-2) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc.

Switching to apt resolver or another one "fixes" the issue. as usual, feel free to reassign or give me some pointers to debug further the issue thanks a lot, Gianfranco
