By mistake, I added an entry called com.canonical.unity.devices.blacklist to dconf when trying to lock the value for the blacklist key under com->canonical->unity->devices. How can I remove it?

Here is what I did before this happened:

Created a file /usr/share/glib-2.0/schemas/00_devices-blacklist.gschema.override with

[com.canonical.unity.devices]
blacklist=['01D3FDBD88BEAC80-OS', '8045-6F4E-PEN']

• Recompiled the schemas with sudo glib-compile-schemas --strict /usr/share/glib-2.0/schemas/.

• Created a file /etc/dconf/profile/user with

  user-db:user
  system-db:local
  system-db:ibus

• Created a file /etc/dconf/db/local.d/00-devices-blacklist with

  [com.canonical.unity.devices]
  blacklist=['01D3FDBD88BEAC80-OS', '8045-6F4E-PEN']

• Created a file /etc/dconf/db/local.d/locks/devices-blacklist with

  # prevent changes to the list of devices not shown in the launcher
  /com/canonical/unity/devices/blacklist

• Created a file /etc/profile.d/dconf-profile.sh with

  export DCONF_PROFILE=local

• Ran sudo dconf update and rebooted.

• My ubuntu gave me some errors regarding /etc/profile so I deleted the /etc/profile.d/dconf-profile.sh, rebooted and it booted without errors, but that entry was added and the devices were still reappearing in the launcher every time I booted.

• Then, I removed /usr/share/glib-2.0/schemas/00_devices-blacklist.gschema.override and edited /usr/share/glib-2.0/schemas/com.canonical.Unity.gschema.xml, changing the default key value to what I wanted. After recompiling the schemas, the devices were no longer showing up on boot.

But that entry is still there. What should I do?
