Public bug reported:
When trying without root:
$ dd if=/dev/zero bs=16M count=1 of=test.img
1+0 records in
1+0 records out
16777216 bytes (17 MB, 16 MiB) copied, 0.0326881 s, 513 MB/s
$ echo foo | cryptsetup luksFormat test.img -
Not compatible PBKDF options.
Whereas for root it still works:
# dd if=/dev/zero bs=16M count=1 of=test.img
Please touch the device.

# echo foo | sudo cryptsetup luksFormat test.img -

For a workaround (from upstream report) with non-root, specify --type
luks1:
$ dd if=/dev/zero bs=16M count=1 of=test.img
1+0 records in
