I successfully tested ibus 1.5.11-1ubuntu2.1 from xenial-proposed,
following the test case in the bug description:
I installed the chromium snap from the stable channel (version
65.0.3325.181, revision 274) and monitor the system journal for apparmor
denials while launching it:
journalctl -f | grep chmod
I observed a denial similar to that one:
audit[16919]: AVC apparmor="DENIED" operation="chmod"
profile="snap.chromium.chromium" name="/home/osomon/.config/ibus/bus/"
pid=16919 comm="chromium-browse" requested_mask="w" denied_mask="w"
fsuid=1000 ouid=1000
I then rebuilt and installed the snap with libibus-1.0-5 and ibus-gtk3
from xenial-proposed (version 1.5.11-1ubuntu2.1):
cd /tmp
cp /var/lib/snapd/snaps/chromium_274.snap ./
unsquashfs chromium_274.snap
wget
https://launchpadlibrarian.net/364009842/libibus-1.0-5_1.5.11-1ubuntu2.1_amd64.deb
wget
https://launchpadlibrarian.net/364009838/ibus-gtk3_1.5.11-1ubuntu2.1_amd64.deb
dpkg -x ibus-gtk3_1.5.11-1ubuntu2.1_amd64.deb squashfs-root/
dpkg -x libibus-1.0-5_1.5.11-1ubuntu2.1_amd64.deb squashfs-root/
snapcraft pack squashfs-root
snap remove chromium
snap install --dangerous chromium_65.0.3325.181_amd64.snap
snap connect chromium:browser-sandbox
I launched it again while monitoring the system journal, and observed that the
chmod denial was gone.
I also verified that ibus input still works in the snap (tested with
ibus-cangjie for traditional Chinese).
