Let's land on wily, test and then make push to our PPA (so we can also test it there, and also revert the workaround), we can include this at our next stable release :-)

Here is what happens: - boot stable, /etc/apparmor.d/cache/usr.bin.ubuntu-core-launcher is mtime of now because we generate the cache on boot - upgrade to edge, /etc/apparmor.d/usr.bin.ubuntu-core-launcher is updated and has the mtime of T (yesterday) when the file was put into the package - on the next reboot the apparmor_parser compares the mtime of the cache/usr.bin.ubuntu-core-launcher (very very recent) with the mtime of the souce usr.bin.ubuntu-core-launcher (much older) -> cache does is *not* re-generate Possible solution: - clear cache on upgrade - make apparmor_parser store mtime of the source file in the header - make apparmor_parser use set the cache file to the mtime of the source file used to generate the cache and re-generate if those get out-of-sync Original description: ---------------------- Rick Spencer ran into the situation that he ended up with a snappy image that gave the following error: """ apparmor="DENIED" operation="mkdir" profile="/usr/bin/ubuntu-core-launcher" name="/tmp/snap.0_pastebinit.mvo_em33Zz/" pid=1092 comm="ubuntu-core-lau" requested_mask="c" denied_mask="c" fsuid=0 ouid=0 """ Running: $ sudo apparmor_parser --skip-cache -r /etc/apparmor.d/usr.bin.ubuntu-core-launcher fixes it. This strongly indicates that the cache has the old content and did not get re-generated on upgrade or image build. I also managed to reproduce this via: 15.04/stable->15.04/edge The image is here: https://drive.google.com/open?id=0B1sb5ymdUGiLa0tUR0pGV3lzR1k&authuser=0 To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1460152/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
