Thank you! It’s easy to fix. Create the main partition and a swap partition in Gparted, choose linux-swap for it. ‘sudo swapon’ /dev/sda2’ in a terminal after quitting Gparted. Calamares will add the swap to fstab. Do ‘sudo swapoff /dev/sda2’ after first boot, and follow: https://wiki.archlinux.org/index.php/Dm-crypt/Swap_encryption#UUID_and_LABEL
