Package: dose-distcheck Version: 7.0.0-6 In case the packages are not co-installable, the indentation of the 'reasons' block is wrong.
I have a minimal reproducible example and what I believe to be a fix: $ dpkg-deb -x dose-distcheck_7.0.0-6_amd64.deb . $ /bin/cat ./pkgs Package: pkg1 Architecture: amd64 Version: 1 Package: pkg2 Architecture: amd64 Version: 2 Depends: pkg3 $ cat ./pkgs | usr/bin/dose-debcheck --explain --failures --coinst pkg1,pkg2 output-version: 1.2 report: - coinst: pkg1 (= 1) , pkg2 (= 2) status: broken reasons: - missing: pkg: package: pkg2 version: 2 architecture: amd64 unsat-dependency: pkg3 - missing: pkg: package: pkg2 version: 2 architecture: amd64 unsat-dependency: pkg3 total-packages: 2 total-tuples: 1 broken-tuples: 1 $ cat ./pkgs | usr/bin/dose-debcheck --explain --failures --coinst pkg1,pkg2 | yq . yq: Error running jq: ParserError: while parsing a block collection in "<stdin>", line 3, column 2 did not find expected '-' indicator in "<stdin>", line 7, column 2. I believe the box should not be closed that early, hence the patch that should fix it: Index: dose3-7.0.0-6/src/algo/diagnostic.ml =================================================================== --- dose3-7.0.0-6.orig/src/algo/diagnostic.ml +++ dose3-7.0.0-6/src/algo/diagnostic.ml @@ -700,7 +700,6 @@ let fprintf ?(pp = CudfAdd.default_pp) ?
