package vanilla-gnome-default-settings 17.10.3 failed to install/upgrade: subproces post-installation script geïnstalleerd gaf een foutwaarde 2 terug

[Marty van Winden]

Purged GNOME.desktop with 'apt purge gnome.desktop', thinking it was not necessary for Ubuntu 17.10.
Saw XSESSION list. No ubuntu.desktop in it. Only plasma.desktop from Kubuntu desktop install.
Installed GNOME.desktop to restore Ubuntu with 'apt install gnome.desktop'.
Dit some editing in Grub-Customizer.
Rebooted PC twice to test Grub settings.
After last reboot got this error.
