Package: lxc Version: 1:1.0.8-1 Severity: normal Dear Maintainer,
When I run commands as lxc-ls, lxc-info, lxc-start, ... on my desktop the following error message is printed in host terminal : lxc: cgmanager.c: lxc_list_controllers: 817 Error connecting to cgroup manager Apart from this message, everything seems to run fine : - creating containers (privileged, at least), - starting containers - stopping containers - using lxc-info or lxc-ls (except from the garbling effect of this message) This is the output of lxc-checkconfig: 8<---- Kernel configuration not found at /proc/config.gz; searching...

I had a quick look at the source code around where this error is raised and noticed this might be somehow related to dbus. I compared the installed packages on both machines (using aptitude search dbus | grep '^i') and they are identical. Thanks in advance for fixing this annoying if not grave at all bug. phep -- System Information: Debian Release: stretch/sid APT prefers testing-proposed-updates APT policy: (500, 'testing-proposed-updates'), (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.3.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=fr_FR.utf8, LC_CTYPE=fr_FR.utf8 (charmap=UTF-8) (ignored: LC_ALL set to fr_FR.utf8) Shell: /bin/sh linked to /bin/dash 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: ii lua5.2 5.2.4-1 -- Configuration Files: /etc/lxc/default.conf [Errno 13] Permission non accordée: u'/etc/lxc/default.conf' -- no debconf information
