I want to install PLASMA DESKTOP but with tricky encryption. I ran into a problem, I can not solve it myself, please help
stages - I boot from live usb, there are two disks I need in the system. Namely sda (installation), sdb (system, on which the system will be installed), sdc (usb on which I want the bootloader Grub and the header LUKS + initramfs
here is my whole process at the very end there is an encryption error that I can’t figure out how to solve
