Hi all,

I am using Arch. In the middle of last year I successfully wiped two
partitions on my laptop following the instructions here:
https://wiki.archlinux.org/index.php/Dm-crypt/Drive_preparation#dm-crypt_wipe_on_an_empty_disk_or_partition

This year I decided to wipe the remaining partition on the same laptop
using the same command command but it fails as below. Any ideas?

~/ lsblk
