package horizon-service-rpm-xx.noarch (which is newer than horizon-service-rpm-xx) already installed

I was working on a patch implementation this morning and encountered an exception almost when we were at the finish line

Exception

To fix this first we need to find out where all these rpm's were present

find / -iname  horizon-service-rpm*

/opt/vmware/share/htdocs/service/cafe/horizon-service-rpm-2.8.3.0-9188306.noarch.rpm

The rpm we are after is at the path

/storage/db/patches/repo/cafe/patchRpms/horizon-service-rpm-3.1.0.0-15433743.noarch.rpm

To fix the problem we had to execute this command

 rpm -Uvh --replacepkgs --oldpackage /storage/db/patches/repo/cafe/patchRpms/horizon-service-rpm-3.1.0.0-15433743.noarch.rpm

Expected outputs are as below

[master] vra-fqdn:/opt/vmware/var/log/vami # rpm -Uvh --replacepkgs --oldpackage /storage/db/patches/repo/cafe/patchRpms/horizon-service-rpm-3.1.0.0-15433743.noarch.rpm

Once this is done go ahead and retry the failed patch installation from VAMI and it works.

horizon build versions are the same across 7.5 and 7.6. So in 7.6, a lower build version might be used

Just make a note that on upgrade this might happen. And when it happens use --oldpackage to replace rpm forcefully
