Yesterday I forgot to say I tried Main Menu Restorer without results. Also, I can't run Synaptic from the menu, an error message appears saying something like synaptic launcher (file or folder) doesn't exist
but I can run it from console. There the message that appears is:
(synaptic:24822): IBUS-WARNING **: The owner of /home/_myusername_/.config/ibus/bus is not root!
(synaptic:24822): Gtk-CRITICAL **: gtk_widget_hide: assertion 'GTK_IS_WIDGET (widget)' failed
/usr/bin/deborphan: El archivo de estado está en un estado inconsiste. (it should be "inconsistente")
Hay uno o más paquetes marcados como medio-instalados, medio-configurados, desempaquetados, esperando-triggers o pendiente-triggers. Saliendo.
It says the status file is in a inconsistent state, 1 or more packages marked as half-installed, half-configured, unpacked, waiting-triggers or pending-triggers. I don't know what is the meaning of that, but it doesn't sound well...
If you need more information, please let me know.
I'll be grateful for your help!!!
