Title:
  [LTS] cryptsetup-initramfs fails when kernel modules are compressed

Status in cryptsetup package in Ubuntu:
  Fix Released
Status in linux package in Ubuntu:
  Invalid
Status in cryptsetup source package in Jammy:
  New
Status in linux source package in Jammy:
  Won't Fix

Bug description:
  This is the same cause as the Mantic bug "cryptsetup autopkgtest fails
  with zstd compressed kernel modules"

  https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/2035120

  where hooks/cryptroot::add_modules() needs postfix wildcards after
  $glob.ko on 2 lines.

  It affects 22.04 LTS with recent kernel or local kernel built with
  CONFIG_MODULE_COMPRESS_*

  I think the fix needs cherry-picking into LTS release(s).

  https://salsa.debian.org/cryptsetup-
  team/cryptsetup/-/commit/8359ad85a541b76f388cdc28f549229e3d71e750

  At boot-time it results in the cryptic (pun intended) messages:

  device-mapper: table: 253:0 crypt: Error allocating crypto tfm (-ENOENT)
  device-mapper: ioctl: error adding target to table
  device-mapper: reload ioctl on luks_os (253:0) failed: No such file or directory
