Bug#954459: lintian: maintainer-shell-script-fails-syntax-check requires /bin/sh → !/bin/bash?

["Chris Lamb" <lamby@debian.org>]

Package: lintian
Version: 2.58.0
Severity: normal

Hi,

The scripts-bashisms and legacy-maintainer-scripts and tests fail
when /bin/sh is set to /bin/bash. This occurs in, for example, the
Reproducible Builds framework:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/lintian.html

Click the build2 link in the left-hand navigation. The cause is that
whilst:

  ./t/tags/checks/scripts/scripts-bashisms/build-spec/debian/postinst

… contains bashisms, it has a /bin/sh shebang so the script is tested
against Bash which, of course, supports Bashisms.

  $ bash -n t/tags/checks/scripts/scripts-bashisms/build-spec/debian/postinst
  $ dash -n t/tags/checks/scripts/scripts-bashisms/build-spec/debian/postinst
  ./t/tags/checks/scripts/scripts-bashisms/build-spec/debian/postinst: 66: Syntax error: "do" unexpected
  $


Regards,
