[Bug 1516037] Re: lxc-start fails with 1.1.5-0ubuntu1
debsums: changed file /etc/default/lxc (from lxc package)
debsums: changed file /etc/apparmor.d/usr.bin.lxc-start (from lxc package)
So I restored the /etc/apparmor.d/usr.bin.lxc-start file to:
#include <tunables/global>
/usr/bin/lxc-start flags=(attach_disconnected) {
#include <abstractions/lxc/start-container>
}
The only thing I remember I did is running aa-complain /usr/bin/lxc-
start a while ago (I don't remember why) and this is what caused the
file to be modified. I reverted aa-complain with aa-enforce /usr/bin
/lxc-start, I restored the apparmor profil and redid the aa-complain and
the file changed again to:
#include <tunables/global>
/usr/bin/lxc-start flags=(complain) {
#include <abstractions/lxc/start-container>
}

Title:
lxc-start fails with 1.1.5-0ubuntu1
Status in lxc package in Ubuntu:
Invalid
Bug description:
After upgrading to lxc 1.1.5-0ubuntu1, lxc-start fails like this:
lxc-start: start.c: preserve_ns: 149 Permission denied - failed to open '/proc/7170/ns/mnt'
lxc-start: start.c: lxc_spawn: 993 failed to store namespace references
lxc-start: start.c: __lxc_start: 1192 failed to spawn 'trusty-lpdev'
lxc-start: lxc_start.c: main: 344 The container failed to start.
lxc-start: lxc_start.c: main: 348 Additional information can be obtained by setting the --logfile and --logpriority options.
This is with a trusty system container. precise system containers
behave similarly. I don't have others to try. Downgrading liblxc1,
lxc, lxc-templates, and python3-lxc to version 1.1.4-0ubuntu3 causes
lxc-start to work again.
