** Summary changed: - LUKS partition on LVM with two disks has wrong device name + LUKS partition on LVM has wrong device name

Install completes and upon rebooting the operating system asks for the encryption passphrase for the LUKS partition (nvme0n1p3_crypt) which does decrypt as expected. Now when logging in and running lsblk it shows the LUKS partition to be in the wrong place. The 1TB disk now has the name nvme1n1 but the LUKS partition on that disk has the name nvme0n1p3_crypt. Output of lsblk: nvme1n1 259:0 0 953.9G 0 disk ├─nvme1n1p1 259:1 0 512M 0 part /boot/efi ├─nvme1n1p2 259:2 0 732M 0 part /boot └─nvme1n1p3 259:3 0 952.7G 0 part └─nvme0n1p3_crypt 253:0 0 952.7G 0 crypt ├─ubuntu--vg-root 253:1 0 930.4G 0 lvm / └─ubuntu--vg-swap_1 253:2 0 976M 0 lvm [SWAP] nvme0n1 259:4 0 477G 0 disk The LUKS partition doesn’t appear to be under nvme0n1p3 but it does on nvme1n1p3 which can be seen when running a luksDump command. Output of luksDump: root@USERPC:~# cryptsetup luksDump /dev/nvme0n1p3 | grep -i "slot 0" Device /dev/nvme0n1p3 doesn't exist or access denied. root@USERPC:~# cryptsetup luksDump /dev/nvme1n1p3 | grep -i "slot 0" Key Slot 0: ENABLED The implications of this so far in my case is not being able to find the correct LUKS partition device name via custom scripts to populate/modify key slots (e.g. 'dmsetup ls' returns the device name nvme0n1p3_crypt). There has not been an issue with Ubuntu decrypting the disk before the login screen.
