Bug#915919: mixxx: Uses vendor-specific patch series file (ubuntu.series)

[Chris Lamb <lamby@debian.org>]

Source: mixxx
Version: 2.1.5~dfsg-1
Severity: important
User: lamby@debian.org
Usertags: package-uses-vendor-specific-patch-series

Dear Maintainer,

mixxx appears to use a vendor-specific patch series file:

  debian/patches/ubuntu.series

This is feature of dpkg that can be used to apply a different series
of quilt patches when the source package is unpacked on different
systems. However, since Debian source packages are usually treated as
a pure transport format this can cause confusion and frustration.

Please migrate away from such series files and consider alternatives
such differing source packages or modify the build process to behave
conditionally or to conditionally patch files explicitly.

After Buster is released, the presence of a vendor-specific patch
series will be a violation of a MUST directive in Debian policy.


Regards,
