Problems with build-snaps on build.snapcraft.io

snap

Hey,

I’m trying to use build.snapcraft.io for a snap using build-snaps.
Unfortunately though it fails and I get these error messages I don’t get when building in a local lxc container:

e[Kerror: cannot perform the following tasks:
- Setup snap "core" (3247) security profiles (cannot setup apparmor for snap "core": cannot load apparmor profile "snap.core.hook.configure": cannot load apparmor profile: exit status 243
apparmor_parser output:
apparmor_parser: Unable to replace "snap.core.hook.configure".  Permission denied; attempted to load a profile while confined?
)

Am I missing something?

I think @ondra ran into this and it might be what @cjwatson is looking into fixing.

It is indeed. I have a fix locally, but need to find time to test it across a few different series and build types to make sure it doesn’t regress anything else.

Have you pin pointed the root cause for this?

More or less. Core snap now does more security setup on configure and
we now need the mac_admin and mac_override capabilities which we’d
previously been dropping. I think there’s also a missing dependency
from snapd on udev which I need to file once I confirm it, but that’s
workaroundable in launchpad-buildd.

@sergiusens @cjwatson ah okay, thanks a lot for the quick response! Is there an issue to track this?
