Description:

Running mkinitcpio -P produces the following error message during the sd-encrypt phase.

> **==> ERROR: file not found: `'**

This error started to appear after a recent upgrade of cryptsetup:

[2021-06-07T17:36:12+0100] [ALPM] upgraded cryptsetup (2.3.5-4 -> 2.3.6-1)

Downgrading to cryptsetup 2.3.5 eliminates the error message.


Additional info:

* package version(s)
cryptsetup 2.3.6.1

* config and/or log files etc.
mkinitcpio.conf relevant lines:
# HOOKS
HOOKS=(systemd autodetect modconf sd-vconsole keyboard sd-plymouth sd-encrypt block sd-zfs filesystems)
* link to upstream bug report, if any

Steps to reproduce:
1) setup mkinitcpio to use the sd-encrypt hook
2) update cryptsetup to 2.3.6.1
3) mkinitcpio is run automatically at the end of the pacman installation and produces the following error:


[2021-06-07T17:37:47+0100] [ALPM-SCRIPTLET] -> Running build hook: [sd-encrypt]
[2021-06-07T17:37:48+0100] [ALPM-SCRIPTLET] ==> ERROR: file not found: `'
[2021-06-07T17:37:48+0100] [ALPM-SCRIPTLET] -> Running build hook: [block]


4) Running mkinitcpio with verbose shows the following lines under sd-encrypt hook related messages.

This bug was first reported on manjaro forums, was advised by a more senior member of the forum to open a bug here.
Hope that's OK.
