I have an external USB hard drive that I configured to automatically mount to a specific location when it is connected. I configured this by:
adding the following line in /etc/crypttab:
device_name UUID=device-uuid-abcd-1234 none luks
... and adding the following line in /etc/fstab:
/dev/mapper/device_name /home/myuser/desired-directory/ ext4 user 0 0
And it was working perfectly!
Whenever I connected the external hard drive, I would be prompted for its encryption password, and after entering the correct password I could find all its data in my configured directory.
The trouble is... when I reboot my laptop, I am booted into emergency mode (presumably only when the external drive is not attached). And no matter what command I issue... I cannot boot in into Ubuntu normally.
If I comment out the line I added to fstab, I can boot normally (I do not have to comment out the line I added in crypttab).
I can add the noauto option to my custom line in the fstab file, but that then requires me to manually mount my hard drive every time I accatch it, and I do not want to have to do that.
What do I need to do so that my computer boots normally and automatically mounts my hard drive whenever it is plugged in?

Is the luks device opened / decrypted when booting without the fstab entry? Initial guess: try noauto &/or nofail in the fstab 4th field

@Xen2050 Hey, thanks for the tips, but those don't give me the desired behavior. :( Yes, I can manually open/decrypt without the entries in fstab and crypttab. I edited my post to make it more clear what the problem is and what I am trying to do.
