> helps as a workaround. I can now build i386 on amd64.qemu is only chosen because of the earlier message "i386 cannot be executed, falling back to qemu-user" which occurs because the arch-test program determined that i386 cannot be executed on amd64. This is not true and maybe there is a bug in the arch-test package in stretch? > > Building armhf or arm64 fails. > > I: installing packages... > /usr/sbin/chroot: failed to run command \u2018dpkg\u2019: Permission denied > env --unset=APT_CONFIG /usr/sbin/chroot > /var/cache/pbuilder/base.cow_arm64 dpkg --install --force-depends > /var/cache/apt/archives//sysvinit-utils_2.88dsf-59.9_arm64.deb ... > /home/user/whonix_dot/Whonix/help-steps/mmdebstrap line 551. > > This might be more a user support question than actual bug.

I have never tested this on stretch and would be surprised if it works there. mmdebstrap makes use of very recent apt and dpkg options and I would not be surprised if these options are not included in stretch yet. Did you try it on the same machine in a buster chroot? Thanks! cheers, josch
