Last week I stood up two XCP-ng hosts with LINSTOR without issue.

This week I am standing up a third XCP-ng host and encounter a show stopping error when I try to install LINSTOR:

Error: Package: xcp-ng-linstor-1.1-3.xcpng8.2.noarch (xcp-ng-linstor)
Requires: sm-linstor
...
Failed to install LINSTOR package: xcp-ng-linstor.

This third host is 100% identical in hardware to the first two hosts. Fresh from-scratch new install of XCP-ng. Here is an output of commands and their results on the third host:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
Failed to install LINSTOR package: xcp-ng-linstor.

It seems the sm* package(s) are missing ? I don't know what to do.

Edit 2024-11-17 1702 CST: yum install xcp-ng-release-linstor indicates xcp-ng-release-linstor is already installed and latest version.
