What Operating System are you using (both controller, and any agents involved in the problem)?

Docker image

Reproduction steps

During boot the plugins are updated via copy_reference_file().
That calls on function versionLT.

The script reports:

SKIPPED plugins/workflow-cps.jpi : Image version (3894.3896.vca_2c931e7935) is older than installed version (3894.vd0f0248b_a_fc4)

But actually version 3894.3896.vca_2c931e7935 is newer, apparently, than 3894.vd0f0248b_a_fc4.
(I'm not sure why the version ID has this structure. One for workflow-cps team I guess.)
https://github.com/jenkinsci/workflow-cps-plugin/releases/tag/3894.3896.vca_2c931e7935

Expected Results

For the plugin to be updated.

Actual Results

Plugin update SKIPPED.

Anything else?

The main Jenkins UI shows the newer version as available for upgrade.

Are you interested in contributing a fix?

FWIW I have tried fixing it, I wasn't able to make it work in bash for all cases. Likely possible just was taking longer than I had.
