New to all this so be please be gentle! I've run a partial upgrade to 16.04.3. I guess I should have investigated why I was offered a partial upgrade before doing it! I now find that it fails to boot. The first error I see is ...
/etc/rc.local: cannot create /sys/bus/usb/devices/4-3/power/wakeup directory nonexistent.
Ubuntu then starts in read-only to protect the file system.
I can start the system by using sudo mount -o remount, rw / and then sudo lightdm
I can see that there is no 4-3 directory in devices but if I try to create it I receive "operation not permitted."
Would this be the correct way to pursue the problem? If so, how can I create the directory.
I did run fsck which came back clean.
UUID from fstab and blkid are as follows....
