The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here (for the next 30 days):

About the archive rebuild: The build was made on debusine.debian.net,
on arm64 using sbuild.

You can find the build task here:

If this is really a bug in one of the build-depends, please use
reassign and affects, so that this is still visible in the BTS web
page for this package.

Thanks,
