Just wiped out everything on my Macbook Pro Retina Early-2015 (Macbook12,1 or something) and installed Ubuntu. Had to use
nodmraid just to get the USB stick to boot.
I wanted to have full-disk encryption, so I selected that. However, I boot up to my Ubuntu install and I cannot type my passphrase! It just prompts me to "Please unlock disk sda3_crypt". I can use the arrow keys in Grub prior to the decryption screen. What should I try? (I don't want to have an unencrypted install if at all possible)
I am using Ubuntu 15.10.
