I'm trying to install git on a developer box and I get the following:

You could try using --skip-broken to work around the problem

** Found 3 pre-existing rpmdb problem(s), 'yum check' output follows:

kernel-2.6.32-431.17.1.el6.x86_64 has installed conflicts bfa-firmware < ('0', '3.2.21.1',     '2'): bfa-firmware-3.0.3.1-1.el6.noarch

kernel-firmware-2.6.32-431.17.1.el6.noarch is a duplicate with kernel-firmware-2.6.32-358.23.2.el6.noarch

kernel-headers-2.6.32-431.17.1.el6.x86_64 is a duplicate with kernel-headers-2.6.32-358.23.2.el6.x86_64

How can I resolve this? I'm not too familiar with CentOS/RHEL

Thanks

In my case I found that something had gone wrong and many packages had been updated without the older versions being removed. Attempts to rebuild the RPM DB did not solve the problem.

One solution that is working is simply to remove the older version and reinstall the newer version.

Looking at the error output each line basically says Update Package is a duplicate with Previous Package, ie:

    kernel-headers-2.6.32-431.17.1.el6.x86_64 is a duplicate with kernel-headers-2.6.32-358.23.2.el6.x86_64

The following seems to work for me:

    rpm --erase --nodeps --noscript kernel-headers-2.6.32-358.23.2.el6.x86_64

The command tells RPM to remove the specific Previous Package without removing any dependencies or running any scripts associated with the task.

Next the package needs to be reinstalled:

    yum reinstall kernel-headers

This time there's no need to specify the exact package version as yum will look for the most recent version and reinstall it.

Yum will output the result of its Yum Check operation during each run. Keep doing this until there are no more duplicate packages listed.

Note that you can query the RPM database directly. If you see lots of messages that include the string glibc, for example, you can get a simple list of packages which have that string in their names like this:

    rpm -qa | grep glibc | sort

Which might produce something like:

    glibc-2.17-157.el7_3.5.x86_64

    glibc-common-2.17-157.el7_3.4.x86_64

    glibc-common-2.17-157.el7_3.5.x86_64

    glibc-devel-2.17-157.el7_3.5.x86_64

    glibc-headers-2.17-157.el7_3.5.x86_64

Now it's more obvious that the previous version of glibc-common must be removed:

    rpm --erase --nodeps --noscript glibc-common-2.17-157.el7_3.4.x86_64

    yum reinstall glibc-common

Try executing following command

yum clean all

rpm --rebuilddb

yum update

yum clean all

yum reinstall glibc glibc-common libgcc

yum upgrade

yum install yum-utils

package-cleanup --problems

package-cleanup --dupes

Root Cause

Interruption in the up2date or yum update process caused the installation of multiple versions of the same package.

Resolution

1. If the system is Red Hat Enterprise Linux 5 or later, the package-cleanup command can be used:


$ package-cleanup --dupes
$ package-cleanup --cleandupes


The --dupes command will list the duplicate packages installed on the machine, while the --cleandupes switch will remove the older versions. package-cleanup command is provided by the yum-utils package.

2. If package-cleanup does not help or the system is Red Hat Enterprise Linux 4, remove packages manually using rpm:


$ rpm -e --justdb <package-name>-<old-version>


The '--justdb' switch is used to ensure that the package removal does not remove its files from the file system, removing it only from the rpm database.

Some duplicates may not removed because they are required by installed packages.
You can try --cleandupes with --removenewestdupes, or review them with --dupes and remove manually.
