Package: debootstrap Version: 1.0.114 Followup-For: Bug #921815 Dear Maintainer,
Reproducable: $ docker run --rm -it --privileged debian:bullseye bash $ apt update && apt install debootstrap $ apt policy debootstrap # shows version 1.0.123 is installed $ debootstrap bullseye chroot Output: I: Target architecture can be executed I: Retrieving InRelease ... I: Extracting zlib1g... W: Failure trying to run: chroot "//chroot" mount -t proc proc /proc W: See //chroot/debootstrap/debootstrap.log for details I: Installing core packages... ... I: Base system installed successfully. Checking output: $ echo $? # return 0 $ ls /proc # its empty! I have noticed when you use a debian stretch container, everything is ok. This means the issue was not there in debootstrap 1.0.89 -- System Information: Debian Release: 10.11 APT prefers oldstable-updates APT policy: (500, 'oldstable-updates'), (500, 'oldstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-18-amd64 (SMP w/4 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages debootstrap depends on: ii wget 1.20.1-1.1 Versions of packages debootstrap recommends: ii arch-test 0.15-2+deb10u1 ii debian-archive-keyring 2019.1+deb10u1 ii gnupg 2.2.12-1+deb10u1 Versions of packages debootstrap suggests: pn squid-deb-proxy-client <none> pn ubuntu-archive-keyring <none> -- no debconf information
