I tried Encrypted persistence and Français>Encrypted pesistenc. Both of them doesnot keep changes made for pesona Desktop and applications confifuration.
The Pesitence method works.
How to get Encrypted persistence workable ?
I did not found if Persistence and Encrypted pesistence are linked or not. I mean if I first used Persistenc way and want to migrate to an Encrypted pesistence does this last use the previously confirgured Persistence method or does it create a new one based on a default setting tha will overwrite the eventually existing Persistence method ?
load linto live from your usb when the desktop appears open a terminal type fdisk /dev/sdb (if this is where your usb driive is located)
now you wiill be greeted with fdisk so press N to create a new partition next just press enter it will use the default settings then press W to write it at the end once this has done open a new terminal type
once rebooted press Encrypted persistence from the grub menu and it will ask you to unlock your partition, now you can save and it will remain the same whenever you reboot
