Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.5 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  nested unprileged container fails to start at mounting /proc

Status in linux package in Ubuntu:
  Incomplete
Status in lxc package in Ubuntu:
  Triaged

Bug description:
  Create a trusty or xenial host.  Probably use ubuntu-lxc/daily ppa to
  work around other bugs.

  Create a privileged container (again either trusty or xenial will do),
  and install ubuntu-lxc/daily ppa there.

  Create an unprivileged container in that container.  It will fail at
  mounting proc using safe_mount.  At this point it is mounting proc
  onto /proc/self/fd/14 flags 14.

        lxc-start 20160208234209.189 ERROR    lxc_utils -
  utils.c:safe_mount:1695 - Operation not permitted - Failed to mount
  proc onto /usr/lib/x86_64-linux-gnu/lxc/proc
