Lintian tag information: inconsistent-maintainer (type: error)

Description (from lintian-explain-tags)

The Maintainer address in a group of related processables is inconsistent
as indicated.

This sometimes happens when environmental variables like DEBEMAIL are set
to different values when building sources and changes separately. Please
use the same maintainer everywhere.

Please refer to Bug#546525, https://wiki.ubuntu.com/DebianMaintainerField,
and Ubuntu Bug#1862787 for details.
