Frugal install on encrypted partition

[Cerinthus]

I've tried AntiX frugal install on my Ubuntu LTS, and MX, encrypted installs, and a plain encrypted partition and it just fails instead of asking for a passhrase.

I was hoping to have either AnitX or MX as a frugal install on my my Ubuntu LTS 2012 macbook, at the moment I have a spare 20G plain ext4 partition I can boot frugally from but kinda seems to defeat the point.

Any ideas?

Post QSI and the error you got.
