That worked for me. I just commented out the line and things work for me.

Thanks

IIRC similar thing occured to me a while ago. Wrong uids in rootfs. Try

I think I found the culprit. This was the first clue:
    49 ?        S      0:00 mountall --daemon

"stop mountall" and manually running that command gives:
mountall: Event failed
mount: permission denied
mountall: mount /sys/kernel/debug [3054] terminated with status 32
mountall: Filesystem could not be mounted: /sys/kernel/debug

On lxd, this is correctly mounted
# df -h /sys/kernel/debug
Filesystem      Size  Used Avail Use% Mounted on
debugfs            0     0     0    - /sys/kernel/debug

Not the case on lxc. A workround is to comment-out this line on
/lib/init/fstab, and reboot (or stop-start) the container:
none            /sys/kernel/debug         debugfs         optional
                                 0 0

The appropriate fix would probably to mount it on
/usr/share/lxc/config/ubuntu.userns.conf?

Anyway, the workaround above works for me.
