Getting parse error when building an image with meta-swupdate using Yocto

Question

I'm trying to design an OTA update system and would like to use meta-swupdate with Yocto, here is what I did:

1. bitbake-layers add-layer ../meta-openembedded/meta-oe/

2. bitbake-layers add-layer ../meta-swupdate

3. bitbake-layer showlayers

NOTE: Starting bitbake server...
layer                 path                                      priority
==========================================================================
meta                  /home/ut/repo/poky/meta                   5
meta-poky             /home/ut/repo/poky/meta-poky              5
meta-yocto-bsp        /home/ut/repo/poky/meta-yocto-bsp         5
meta-oe               /home/ut/repo/os-dev/yocto/meta-openembedded/meta-oe  6
meta-swupdate         /home/ut/repo/os-dev/yocto/meta-swupdate  6

In conf/local.conf : I set MACHINE ?= "qemuarm64"

And build:

bitbake swupdate-image

This is what I get:

ERROR: ParseError at /home/ut/repo/os-dev/yocto/meta-swupdate/recipes-support/swupdate/swupdate.inc:10: unparsed line: 'LICENSE:${PN}-lua = "LGPLv2+"'                                     | ETA:  --:--:--

Do not use the master branch of https://github.com/sbabic/meta-swupdate

Use the branch that is compatible with your poky branch. (dunfell, zeus, ...)

For example, in dunfell branch it is fixed:

LICENSE_${PN}-lua = "LGPLv2+"
LICENSE_${PN}-www = "MIT"
