*Hi,
I want to install xCAT on my server which can not access the internet. This software need may dependecy packages, so I download all of them one by one with http://us.archive.ubuntu.com/ubuntu/dists/precise/main/binary-amd64/ and http://us.archive.ubuntu.com/ubuntu/dists/precise/universe/binary-amd64/. And run dpkg-scanpackages* . > Packages to create the local repository. But I met the error show on the title. Thanks.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
*libc6 : Depends: tzdata but it is not going to be installed
*libxml-sax-perl : Depends: perl but it is not going to be installed
****************** Depends: libxml-namespacesupport-perl but it is not going to be installed
****************** Depends: libxml-sax-base-perl but it is not going to be installed
****************** Depends: ucf (>= 0.28) but it is not going to be installed
****************** Recommends: libxml-sax-expat-perl but it is not installable
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. In fact these 4 packages are all can installed by apt-get, why the libxml-sax-perl can not be installed?
