I am pretty new to both yocto and swupdate but I guess there is some small mistake on swupdate license checksum. Here is the error I got:
ERROR: swupdate-image-1.0-r0 do_populate_lic: QA Issue: swupdate-image: The LIC_FILES_CHKSUM does not match for file:///home/user/poky-morty/LICENSE;md5=3f40d7994397109285ec7b81fdeb3b58
swupdate-image: The new md5 checksum is 4d92cd373abda3937c2bc47fbc49d690
swupdate-image: Check if the license information has changed in /home/user/poky-morty/LICENSE to verify that the LICENSE value "MIT" remains valid [license-checksum]

Have a nice day.
