Hi I have accidentally removed all
trusted.pgp even directory with
/etc/apt/. But I have restored with
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32 for example and try to add all key but when i try to upgrade, every thing seems good, but for some reason, some software return error like,
No such key 'button-layout' in schema 'org.gnome.mutter:Pantheon' as specified in override file '/usr/share/glib-2.0/schemas/20_elementary.pantheon.wm.gschema.override'; ignoring override for this key.
There's another error that I don't take note of.
How can I fix this??
