If you hit a problem that this troubleshooting guide doesn't help, you can ask for support. In all cases, it might be helpful to point to these instructions so that people know what you are trying to do.

This is usually because either /etc/crypttab or /etc/fstab is incorrect. To solve, do the following.

  1. Boot into a Live CD.
  2. Check your keyboard.

  3. Open a terminal and then unlock your partition.

  4. Mount your partitions.

  5. Carefully repeat Fix crypttab.

  6. Carefully check Fix fstab to check that it all looks correct.

  7. Reboot your computer.

3. Computer fails to boot after upgrade or new installation

On some occasions, you might find that the computer fails to boot. See Known Bugs for details.

  1. Boot into a Live CD.
  2. Check your keyboard.

  3. Open a terminal and then unlock your partition.

  4. Mount your partitions.
