The "completely off" refers to option 4, where the correct source package name would have been libbsd.

When you give reportbug a binary package name, reportbug tries to determine the corresponding source package name like this:
https://salsa.debian.org/reportbug-team/reportbug/-/blob/master/reportbug/utils.py#L555

What happens here is that the binary package lookup in the apt cache fails (probably because this is an udeb package), but the SourceRecords().lookup() with the given package name succeeds. Shouldn't this only succeed if there is a source package with this name? The documentation does not mention binary packages in the section on SourceRecords().lookup().

I'm wondering whether reportbug is using apt's python bindings incorrectly. What would be the correct way to obtain the source package name of an udeb package using python3-apt?
