Bug#842786: numix-icon-theme: FTBFS (dpkg-source can't extract orig tarball)

[Santiago Vila]

Package: src:numix-icon-theme
Severity: serious

Dear maintainer:

I tried to build "numix-icon-theme" in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

--------------------------------------------------------------------------------

The build was made on a QEMU/KVM virtual machine with sbuild and
union-type=overlay.

The original tarball does not contain any directories:

$ tar tvf numix-icon-theme_0~20160619.217701b.orig.tar.xz | grep ^d
[ no output at all ]

so that's apparently why this happens.


This is probably a bug in Linux implementation of "overlay", used by
sbuild, but as a workaround, I would recommend that the orig tarball
is repackaged to avoid this.

It could also be a bug in tar, or in dpkg-source for not passing
appropriate options to tar. I'm using X-Debbugs-Cc to reach
potentially interested people.

Thanks.
