Package: lxc Version: 1:1.0.8-1 Followup-For: Bug #800699 This seems to be the same issue as https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=773384 which was dismissed with "this will never work". But it will, it's fixed in upstream, see https://github.com/hallyn/lxc/commit/473ebc77d6762c2ec49fe59983dabc04f695fd01
Besides, it's not just launching 64b containers with 32b userspace. Currently I can't launch any containers at all unless I manually setarch i686, otherwise I'm getting the same errors: lxc-start: seccomp.c: get_new_ctx: 192 Seccomp error -17 (Unknown error -17) adding arch: 2 lxc-start: start.c: lxc_init: 388 failed loading seccomp policy lxc-start: start.c: __lxc_start: 1065 failed to initialize the container lxc-start: lxc_start.c: main: 341 The container failed to start. lxc-start: lxc_start.c: main: 345 Additional information can be obtained by setting the --logfile and --logpriority options. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (980, 'testing'), (980, 'stable'), (500, 'unstable-debug'), (500, 'unstable'), (500, 'stable'), (200, 'experimental'), (1, 'experimental-debug') Architecture: i386 (x86_64) Foreign Architectures: amd64 Kernel: Linux 4.4.0-lis64+ (SMP w/4 CPU cores; PREEMPT) Locale: LANG=cs_CZ.UTF-8, LC_CTYPE=cs_CZ.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages lxc depends on: ii init-system-helpers 1.24 ii libapparmor1 2.10-2+b2 ii libc6 2.21-6 ii libcap2 1:2.24-12 ii liblxc1 1:1.0.8-1 ii libseccomp2 2.2.3-2 ii libselinux1 2.4-3 ii python3 3.4.3-7 Versions of packages lxc recommends: ii cgmanager 0.39-2 ii debootstrap 1.0.75 ii openssl 1.0.2e-1 ii rsync 3.1.1-3 Versions of packages lxc suggests: pn lua5.2 <none> -- no debconf information -- Tomáš Janoušek, a.k.a.
