Unprivileged container used to run, after update error: wait_on_daemonized_start: 837 Received container state "ABORTING" instead of "RUNNING"

So I have this unprivileged centos 7 container which used to run just fine. Recently (probably after a system update) lxc-start fails with the mentioned error message.

I’m having trouble making hands and tails of the logfile.
I might be affected by apparmor 4.x breaks systemd user namespacing in lxc containers · Issue #4529 · lxc/lxc · GitHub as I do have apparmor 4.0.3…
The mentioned workaround

echo 0 > /proc/sys/kernel/apparmor_restrict_unprivileged_userns
echo 0 > /proc/sys/kernel/apparmor_restrict_unprivileged_unconfined

errors out and has no effect on my system.
Any pointers on what is going on here and how to solve this would be appreciated.

System is OpenSuse Tumbleweed, x86_64, lxc 6.0.4

There’s a pretty good chance that you’re in one of the situations where start: Re-introduce first SET_DUMPABLE call · lxc/lxc@2663712 · GitHub is needed.

We’ve had a bunch of the distro maintainers to cherry-pick this small fix, but I don’t think OpenSuse has been one of them.

@cyphar do you know who to poke to have the lxc package in OpenSuse include this fix?

Is there some kind of (temporary) workaround? Disabling AppArmor or compiling lxc from source to make things work again until the official distro package gets fixed? Pointers are much appreciated.

Manually rebuilding the distro package with the commit linked above added should do the trick.

This isn’t related to AppArmor so no easy config tricks can be pulled to avoid the issue.

After a git clone form the repo on github I followed the build instructions on GitHub - lxc/lxc: LXC - Linux Containers. The build finished successfully but lxc-start now errors out with

lxc-start: centos7: ../src/lxc/parse.c: lxc_file_for_each_line_mmap: 129 Failed to parse config file "/usr/share/lxc/config/common.conf" at line "lxc.seccomp.profile = /usr/share/lxc/c

I found a hint about seccomp needing to be enabled explicitly https://discuss.linuxcontainers.org/t/seccomp-configuration-not-loaded-by-lxc/5102/2 but I am struggling to accomplish that as I am unfamiliar with meson. (configure, make… seems to be a thing of the past, right?)

seccomp isn’t very likely to be the problem there, the prefix is more likely to be the issue.

  • rm -Rf build/
  • meson setup build -Dprefix=/usr
  • meson compile -C build
  • sudo ninja -C build install

I decided to start fresh:

  • git clone git@github.com:lxc/lxc.git
  • git checkout stable-6.0
  • meson setup build -Dprefix=$HOME/lxc/bin ( ← I prefer a local folder for testing…)
  • meson compile -C build
  • sudo ninja -C build instal
