[Pkg-fglrx-devel] Bug#697395: lintian: False positive: preinst-uses-dpkg-maintscript-helper-without-predepends

[Patrick Matthäi]

Package: lintian
Version: 2.5.10.3
Severity: normal

Hello,

I have found an false positive about preinst-uses-dpkg-maintscript-helper-without-predepends.
For example fglrx-driver:

lintian complains about:
  preinst-uses-dpkg-maintscript-helper-without-predepends

withing every package. The extended description says:

	N:    The package contains a preinst maintainer script that uses
	N:    dpkg-maintscript-helper but does not declare a versoned pre-dependency
	N:    on dpkg (>= 1.15.7.2~) that provides that script.

So adding a Pre-Depends on dpkg (>= 1.15.7.2~) is enough and will work to prevent this
message, but fglrx-driver also switched to xz compression!
lintian suggests:

	N:    The deb uses xz compression for the data member, which requires a
	N:    Pre-Depends on dpkg (>= 1.15.6~). This is trivially satisfied in Debian,
	N:    but it can complicate upgrades from Ubuntu Lucid where dpkg 1.15.6 is
	N:    not currently available.

So the correct way (to prevent faults abouts preinst-uses-dpkg-maintscript-helper-without-predepends
and data.tar.xz-member-without-dpkg-pre-depends) would be to add a Pre-Depends on dpkg (>= 1.15.6~).
Done, but lintian still complains about the preinst-uses-dpkg-maintscript-helper-without-predepends
one.

You can reproduce it with svn://svn.debian.org/svn/pkg-fglrx/fglrx-driver/branches/experimental
revision 1146 for example.
