"Write the changes to disks?" While installing Lubuntu

[Juje_Sibzamini]

While installing Lubuntu with disk encryption I had the bug, so I did ctrl+alt+t and typed sudo swapoff --all.

Then I proceeded to install it and then this popup came:
"Write the changes to disks?
If you continue, the changes listed below will be written to the disks. Otherwise, you will be ale to make further changes manually.

The following partitions are going to be formatted:
LVM VG lubuntu-vg, LV root a ext4
LVM VG lubuntu-vg, LV swap_1 as swap"

I don't know what I am doing here, I just want to have full disk encryption.

There's currently no OS on my laptop so I am trying to install lubuntu.

What I do when I see this is Choose "Back" and then continue. The popup does not reappear.

Other errors have taken its place. So now I have decided not to encrypt it. Can I still install it or do I need to reverse the swapoff - all command I placed earlier? How do I do that?
