Comment 26 for bug 2072811

@Robie Basak (racb), thanks for the fix - seems to work for me:

1. Re-enabled the original profile
2. Enabled proposed repo
3. Installed updated apparmor version (4.0.1really4.0.0-beta3-0ubuntu0.1)
4. Reboot
5. Test KeepPassXC, Ksnip - can save again

p.s. I no longer see 'bwrap' under /etc/apparmor.d (`grep -ir bwrap /etc/apparmor.d`)

Details of install and test:

```
# Enable proposed

cat <<EOF >/etc/apt/sources.list.d/ubuntu-$(lsb_release -cs)-proposed.list
# Enable Ubuntu proposed archive
deb http://archive.ubuntu.com/ubuntu/ $(lsb_release -cs)-proposed restricted main multiverse universe
EOF

cat <<EOF >/etc/apt/preferences.d/proposed-updates
# Configure apt to allow selective installs of packages from proposed
Package: *
Pin: release a=$(lsb_release -cs)-proposed
Pin-Priority: 400
EOF

# Re-enable brwap profile

aa-enforce /usr/bin/bwrap

# Install fix
