Snapped LXD has stopped working - aa-exec: Permission denied


#1

trying to run snapcraft cleanbuild I’m getting a permission denied error from the lxd where the wrapper at /snap/lxd/4375/wrappers/lxc tries to re-execute itself using aa-exec. This command does not exist in the snap and therefore cannot be executed. LXC and cleanbuild therefore just does not work.

$ snapcraft cleanbuild
cat: /proc/self/attr/current: Permission denied
/snap/lxd/4375/wrappers/lxc: 6: exec: aa-exec: Permission denied
Something seems to be wrong with your installation of LXD.
Refer to the documentation at https://linuxcontainers.org/lxd/getting-started-cli.

“aa-exec” does exist in the snap. The error above most likely indicates that the LXD snap somehow got disconnected from the “lxd-support” interface.

sudo snap connect lxd:lxd-support core:lxd-support
sudo systemctl restart snap.lxd.daemon

May help with that.


#3

something on my system is wonky then:

$ sudo snap connect lxd:lxd-support core:lxd-support
error: snap "core" has no slot named "lxd-support"

#4

Hmm, something pretty wrong must be going on with your system then…

root@snap-ubuntu-1604:~# snap connect lxd:lxd-support core:lxd-support
root@snap-ubuntu-1604:~# snap version
snap    2.27.6
snapd   2.27.6
series  16
ubuntu  16.04
kernel  4.10.0-35-generic

#5

Do you see the “lxd-support” interfaces listed in “snap interfaces”?


#6

only the one line mentioning lxd-support:

$ snap interfaces | grep lxd-support
-                               lxd:lxd-support

#7

in fact, it seems the list of interfaces is really different to how I last remember it:

#14

Thank you, do you have the logs from earlier days? I think journalctl only shows that from the last boot by default. You may have to fiddle with options.

Is anything under mounted under /snap?


#15

it looks like I’ve only got the current boot available. journalctl --list-boots only lists the current boot. Everything under /snap is correctly mounted.


#16

logging always happens in parallel to journald and rsyslog … the syslog files should have older data …


#17

complete syslog* entries mentioning snapd (minus apparmor audit lines - I can repaste with those included if needed)

Where do I find logs for snapd?
#18

this might be related - apparmor didn’t start:

#19

I have the same errors on my 17.10 system for apparmor and yet my snap interfaces output looks normal (with and without lxd installed). So while the apparmor errors are something that @jdstrand is probably interested in look like they are not be the cause of the issue.


#20

webrowser-app needs apparmor-easyprof-ubuntu installed. Its profile didn’t load. The lxd warnings are expected because of the lxd-support interface use of ‘ux’. It should be noted that apparmor did start and you have profiles loaded (you can see this with ‘sudo aa-status’), but because some profiles failed to load, it exited with error.
