My computer booted to a black screen with this error message.
Welcome to emergency mode! After logging in,type "journalctl -xb" to view
system logs, "systemctl reboot" to reboot, "systemctl default" or ^D to
try again to boot into default mode.
journalctl -xb snippet (what I think is wrong):

Following that the next boot is slow but successful. However, the WiFi is not able to connect to the router.
In this situation I can make some improvement by using a UBUNTU Live from a USB store. I run:
$ sudo -i
$ fsck -Cccfv /dev/sda8
sda8 is the home partition on my disk.
The same error occurs after a 3 - 4 days long period. What should I do?
