What does this error mean, and how can I solve it?

The what is evident by the error, as to why the drive is unavailable , based on the disk utility output the drive appears to be failing. You also appear to be dual booting Windows. If fast-start is enabled under Windows (the default) the file system is unavailable due to the hibernation file Windows leaves there. This is actually for your protection. If you were to make changes to the file system with Ubuntu while Windows is in hibernation status (fast-boot), you would lose those changes upon rebooting (resuming) Windows.

The first thing to try is disabling fast-boot from windows. This should allow you to mount the drive with Ubuntu.

I recommend replacement of the drive ASAP and insuring that you have current backups of all your critical data.
