I've a strange issue. After restarting my laptop, top menu bar is blinking and disappearing. I'm getting the below error If I run the command
wingpanel --toggle-indicator app-launcher:
[15:24:33.917940 GLib-GObject-Critical] g_object_new_valist: object class 'SecurityPrivacyPlug' has no property named 'supported-settings'
wingpanel: symbol lookup error: /usr/lib/x86_64-linux-gnu/switchboard/personal/pantheon-security-privacy/libpantheon-security-privacy.so: undefined symbol: switchboard_plug_get_supported_settings
What should I do to fix it?
PS:// Restarting my laptop,
apt-get upgrade didn't help
