[buildd-tools-devel] Bug#843692: sbuild: extra-packages architecture check emits warnings because it can't find the source debs

[Felipe Sateler]

Package: sbuild
Version: 0.72.0-2
Severity: normal

Hi,

sbuild is generating errors like this when pasing --extra-package:

dpkg-deb: error: failed to read archive 'dpkg_1.18.14+nmu1_i386.deb': No such file or directory
E: read_command failed to execute dpkg-deb
Use of uninitialized value $arch in scalar chomp at /usr/share/perl5/Sbuild/Build.pm line 1295.
Use of uninitialized value $arch in string ne at /usr/share/perl5/Sbuild/Build.pm line 1298.
Use of uninitialized value $arch in string ne at /usr/share/perl5/Sbuild/Build.pm line 1298.
Use of uninitialized value $arch in concatenation (.) or string at /usr/share/perl5/Sbuild/Build.pm line 1300.
W: Extra package dpkg_1.18.14+nmu1_i386.deb of architecture  cannot be installed in the chroot

Enabling debug output suggests the problem is that the program is
executed on the host, but on the wrong directory:

I: /bin/sh -c cd '/home/felipe' && 'dpkg-deb' '--field' 'dpkg_1.18.14+nmu1_i386.deb' 'Architecture'
D: Running command: /bin/sh -c cd '/home/felipe' && 'dpkg-deb' '--field' 'dpkg_1.18.14+nmu1_i386.deb' 'Architecture'
dpkg-deb: error: failed to read archive 'dpkg_1.18.14+nmu1_i386.deb': No such file or directory
E: read_command failed to execute dpkg-deb

The `cd` needs to be to the original cwd though.
