Comment:
it should print "package not found in repositories". you can try it out locally, the message comes from xpkgdiff itself.

example, for a package that exists neither locally or remotely:
```diff
$ xpkgdiff -f rnote
--- /tmp/xpkgdiff.okYGq/rnote.repo	2022-05-06 15:45:41.909674652 -0400
+++ /tmp/xpkgdiff.okYGq/rnote.local	2022-05-06 15:45:41.933674688 -0400

-Package 'rnote' not found in repositories
