If this change is expected (e.g. you have upgraded to a new version without updating the checksums) then you can use these lines within the recipe:
SRC_URI[md5sum] = "8df71c75dcf68ad4f7b97114c2f69df0"
SRC_URI[sha256sum] = "839900d1a06f7acc798e02b05f3613662c1cd61d30ae659c9676e03b454b59dc"
Otherwise you should retry the download and/or check with upstream to determine if the file has become corrupted or otherwise unexpectedly modified.
