Full Discussion: Difference in conflict resolving between yum and rpm installs
Operating Systems Linux Red Hat Difference in conflict resolving between yum and rpm installs Post 302753123 by gazza-o on Tuesday 8th of January 2013 06:10:34 AM

Thanks Guys, that is really helpful but here is my issue.

I need to find away (within the package - not yum.conf) of preventing an install upgrading my package via yum install if a previous version exists.

Basically, I can have a DEV, UAT and PRD package installed on the same server at one time and they have many shared files so upgrading DEV, would break UAT and PRD at the older version. My preference would be for it to abort and advise that all packages need to be removed (DEV/UAT/PRD) before the new version is installed.

Is there an easy way to achieve this? Can I just do an rpm -qa packagname and exit 1 in the pre section or is there a simpler way?

Alternatively, is there a way in the spec file to ensure that if I upgrade DEV, that UAT and PRD get updated at the same time.

Thanks for everyone's help.

pkgkde-override-sc-dev-latest

PKGKDE-OVERRIDE-SC-DEV-LATEST(1)			User Contributed Perl Documentation			  PKGKDE-OVERRIDE-SC-DEV-LATEST(1)

NAME

       pkgkde-override-sc-dev-latest - loosen kde-sc-dev-latest Break restrictions

SYNOPSIS

       pkgkde-override-sc-dev [-bbase_version] [-vversion]

DESCRIPTION

       pkgkde-override-sc-dev-lastest is a helper utility which can be used to generate a dummy kde-sc-dev-latest package without Breaks field
       that is present in the original version. Original kde-sc-dev-latest package is used to force KDE Software Compilation modules to be built
       against the latest version of the KDE Development Platform modules without bumping versions of a bunch build dependencies for each KDE SC
       module. However, while original kde-sc-dev-latest does not cause problems when building in clean chroots, the restrictions imposed by its
       Breaks field might be undesirable on the maintainer system when:

       o   the maintainer wants to (test)build KDE module version X.Y.A against KDE Development Platform X.Y.B where (A > B);

       o   the maintainer builds a new upstream version of the some KDE Development Platform module on the system that has an old version of some
	   KDE Development Platform packages installed. For example, even if kdepimlibs does not build depend on kdebase-workspace-dev, original
	   kde-sc-dev-latest may prevent kdepimlibs X.Y.A to be built on the system which has kdebase-workspace X.Y.B (where A > B) installed.

       By default, pkgkde-override-sc-dev-latest generates a dummy kde-sc-dev-latest package in the current working directory that is based on the
       current "candidate" version of the original kde-sc-dev-latest (as per apt-cache policy). You may specify a base version with the -b option.
       The resulting dummy kde-sc-dev-latest override package will have "base_version+override" as its version unless another one is specified
       with -v option. Once the package is generated, you can install it like:

	 # dpkg --install kde-sc-dev_<version>+override_all.deb

OPTIONS

       -bbase_version, --basever=base_version
	   The version of the original kde-sc-dev-latest package to base an override package on. It must be available in the APT database on the
	   system. You may also pass special value "latest" to select the latest available version in the APT database. If you specify "priority",
	   the latest version with the highest priority will be selection. By default (if this option is not specified), candidate version is
	   selected

       -vversion, --version=version
	   Generate an override package with the specified "version+override" rather than default "base_version+override" version.
