Package: lintian Version: 2.5.22.1 Severity: wishlist Tags: patch Hi!
The lzma and bzip2 compressions are deprecated, and dpkg-deb emits warnings (since 1.16.4 and 1.17.7 respectively) when trying to build such packages. It would be nice to get a warning emitted from lintian, to help in getting packages using those compression formats being updated. I've added a new tag uses-deprecated-compression-for-data-tarball for these, instead of reusing malformed-deb-archive, because these packages are just fine and will keep being supported at extraction time for the foreseeable future, even when creating them is disallowed. I've not tested the patch. Thanks, Guillem
