I tried to update my elastic-search app (on TrueNAS-SCALE 24.10.2.2) from 1.2.14 (app version is 8.17.4) to 1.3.4 (app version 9.0.2), the latest one as of June 19, 2025. The container does not start, and the logs indicate that I cannot upgrade a node from 8.17.4 directly to 9.0.2, that I must go through 8.18.0 first.
However, the only option available when clicking the upgrade button is 1.3.4 (in the dropdown), no other versions are listed. For now, I can roll back the update to 1.2.14, and continue to work, but how would I force an update to 8.18 if it isn’t listed?
Here is the relevant log entry, reformatted for clarity:
