Is it possible to encrypt a LMV partition after having installed an OS?
I just finally managed to get LVM but I couldn't figure out how to get it encrypted. The installer didn't seem to provide for that to happen.
To be more specific, I installed Lubuntu 18.10 which utilizes the Calamares installer.
I've installed Lubuntu successfully but it's not encrypted.
Is it possible to use LUKS to do something at this point or is there an alternative?
EDIT: I am aiming for FDE. I want all partitions encrypted (/, home, swap).
