ERROR: Metadata for package util-linux-openrc-2.38.1-r1 is too long.

Since Nov 24 the following happens when updating this Alpine/edge system:

I.e. a bunch of other packages need to be updated, but then apk somehow stumbles over util-linux-openrc and quits, albeit with an error code of 0, but without committing its changes. Downloading and extracting the package did not reveal anything suspicious on first sight:

# apk fetch -v util-linux-openrc

...or maybe the license tag has gotten too long? :-)

Note: that particular error message was mentioned a few days ago in #14371 too.
