When fsck is finished checking and repairing the filesystem, type reboot into the command prompt and press “Enter.” Conclusion. Fsck on the Mac isn’t as powerful as fsck on Linux, but it can still be a lifesaver if you end up with a corrupted boot disk or damaged hard drive. After successfully correcting a filesystem, fsck will print the number of files on that filesystem, the number of used and free blocks, and the percentage of fragmentation. If sent a QUIT signal, fsck will finish the filesystem checks, then exit with an abnormal return status that causes an automatic reboot to fail.

Lets first check your file system for errors.

To check the file system on your Ubuntu partition...

• boot to the GRUB menu
• choose Advanced Options
• choose Recovery mode
• choose Root access
• at the # prompt, type sudo fsck -f / or sudo fsck -f /dev/sda1
• repeat the fsck command if there were errors
• type reboot

If for some reason you can't do the above...

Fsck Manual Machine

• boot to a Ubuntu Live DVD/USB
• open a terminal window
• type sudo fsck -f /dev/sda1
• repeat the fsck command if there were errors
• type reboot

From there, you should be able to drop to some maintenance shell (if not already opened), where you may run fsck -yf /dev/sda1.

If there are any errors rerun fsck -yf /dev/sda1

To login as usual simply run exit and proceed normally.

If you have to ask those questions then you really should not be booting into single user mode. You can cause real damage to your system.

Briefly fsck is a program to check and repair disk drives. The root device mounted read only means the root disk is not writeable,

If you thing there is problems with your system boot into safe mode (hold the shift key while booting) and see if the problems go away or change.

BTW you never said why it is you are booting into single user.
