I recently updated my Linux 4.9.0-8 debian 6.3.0. However, when I restarted my machine, ended up having the message in the title. Preventing me from accessing the graphical terminal. I can't access my files which is very serious. All icons and images fail to load. I can't open any windows but GNOME seems to work as if it were normal.
I've tried to update GRUB via recovery mode but other than that, I don't have many ideas.
