Package: libdvd-pkg
Version: 1.4.0-1-1
Severity: normal
Tags: patch
With dpkg version 1.18.7 (possibly other versions > 1.18.4 as well),
'dpkg-reconfigure libdvd-pkg' fails to build anything. It always ends up
with the following error:
libdvd-pkg: dpkg database is locked. You may need to use command "sudo
dpkg-reconfigure libdvd-pkg".
libdvd-pkg: Building and installation of package(s) [libdvdcss2
libdvdcss-dev] postponed till after next APT operation.
The problem occurs in /usr/lib/libdvd-pkg/b-i_libdvdcss.sh, which uses
"dpkg -i /dev/zero" to determine the lock status of dpkg. Newer versions
of dpkg produce the following error:
dpkg: error: archive '/dev/zero' is not a regular file
which also returns an error status of 2, hence nothing ever builds.
Purging or removing a non-existent package should restore the original
behaviour. I have attached a patch with this fix.
Best regards,
Carlos

Subject: [PATCH] Use alternative way to check if dpkg database is locked
Version 1.18.7 of dpkg also returns an error status of 2 when
attempting to install /dev/zero, so this method can no longer
be used to check the lock status. Trying to purge a non-existent
package achieves the original behaviour.
