[xubuntu-users] Disk encryption boot oddity

[Peter Flynn]

I encrypted the hard disk of my Dell D810 when installing 15.10 and it's
been working fine -- with one oddity: when I give the encryption
passphrase at boot time, I get two messages at the bottom of the screen:

cryptsetup: unknown fstype, bad password or options?
cryptsetup: sda5_crypt set up successfully

It then proceeds to boot normally without error. My disk layout is:

Filesystem     1K-blocks     Used Available Use% Mounted on
udev             1013792        0   1013792   0% /dev
tmpfs             206268     5940    200328   3% /run

tmpfs             206268       12    206256   1% /run/user/1000

As it works, it's not really important, but I'm curious to know why it
thinks it's an unknown fstype when it clearly isn't. It's also a message
which would obviously cause a newcomer to get worried, which is usually
A Bad Thing...
