As a noob to Linux I do not know if it is possible to encrypt whole drive with current calamares installer

I did a fresh install of Lubuntu with these options in calamares

erase disk +encrypt system 

When rebooting it asks :

Welcome to GRUB! Attempting to decrypt master key...  
Enter passphrase for hd0

After decrypting I have only to log in as user

Normally we have to put password under Lubuntu logon

Is in this case the complete system encrypted ? Is the grub prompt normal ?

Here is the output of lsblk

sda                                8:0    0 238,5G  0 disk  
├─sda1                             8:1    0   300M  0 part  /boot/efi
└─sda2                             8:2    0 238,2G  0 part  
  └─luks-5fc-xx-xxx-xxxx-xxx
                                 253:0    0 238,2G  0 crypt /
sr0                               11:0    1   3,7M  0 rom   /media/

Everything but /boot/efi is encrypted, yes.

This is indicated by the fact that sda2 only holds a Luks volume (which is the encryption feature used by Ubuntu and many other Linux distros), which is in turn mounted on /.

The grub prompt is perfectly normal, given that the kernels reside on an encrypted partition, and /boot/efi only contains the bootloader itself. It has to ask for passphrase to read the kernel it has to load.

  • but when i open disk utility i see 2 free space areas . why are they created and why unencrypted ? i have added picture in question. can you take a look. and how about lvm .ist it better to use lvm with full disk encryption? – zayers Jun 18 at 18:00
  • What free space to you see? The partitions adds up to the size of the disk. And LVM+LUKS is no more safe than only LUKS. LVM is a management layer, and doesn't really impact security. With your setup, you only have one partition for everything anyway, so LVM doesn't make a lot of sense. – vidarlo Jun 18 at 18:04
  • i have edited question. look at foto. there are 2 small space areas created automatically . i dont think encrypted – zayers Jun 18 at 18:08
  • There's a tiny free space in front and at the end, which is not used for anything nor encrypted. – vidarlo Jun 18 at 18:11
  • in debian installer i always used entire disk and setup encrypted lvm to encrypt whole disk ...was my setup with calamares above as whole drive encryption ? – zayers Jun 18 at 18:18
