[Bug 1804314] Re: Wrong WARNING Option 'hash' missing in crypttab

[Xavier Gnata]

Thanks!

https://blog.botux.fr/fr/2015/02/installation-ubuntu-utopic-14-10-encryption-manuelle-lvm-on-luks/
is wrong towards the end.

Nothing special is needed in /etc/default/grub and /etc/initramfs-
tools/conf.d/cryptroot shall not be created.

Simply put
CryptDisk UUID=xxxxxxxx none luks in your /etc/crypttab and the warning is gone.


It would be cool if the installer setup all that automatically. It works in full disk but not in dual boot. 

You can close this bug.

Title:
  Wrong WARNING Option 'hash' missing in crypttab

Status in cryptsetup package in Ubuntu:
  Invalid

Bug description:
  I have installed kubuntu 18.10 on an encrypted partition.

  I have written a /etc/crypttab
  CryptDisk UUID=c9deed35-610e-4328-b8e7-079e95d43f76 none luks,hash=sha256,tries=3

  At each boot, I get this warning "cryptsetup: WARNING: Option 'hash' missing in crypttab".
  I tried with and without the hash=sha256 but the warning does not change.
