Package: lintian
Version: 2.141.0
Severity: serious
Justification: does not work
X-Debbugs-Cc: tg@mirbsd.de

In my pbuilder hooks, I install and run lintian after build,
even with Recommends:

=09apt-get --purge -y -o APT::Install-Recommends=3Dtrue install lintian

This currently fails to produce a working lintian:
