I have 2 self-hosted discourse forums on 2 separate VPS’es. They were nearly up-to-date with latest, but not exactly on the same version. Last week I tried to update them via the Update UI. For both forums this resulted in an error in the Discourse (not the docker_manager) install process, and the updates did not succeed. After that the Update UI showed as follows: [Update UI says "You are running an old version of the Discourse image" and requests a launcher rebuild app via SSH.] No problem. I went into SSH and updated both via ./launcher rebuild app and that worked like a charm… I thought. But not quite. Both forums are now at 2026.11.0-latest. When I go to the Update UI on either forum the regular UI chrome is not showing, and it is still showing the above message, requesting SSH update. I expected the UI to be working, alllowing UI-based updates again. (Unfortunately I do not have logs to attach on the update errors. I also did not yet do the rebuild app for the second time in a row, wanted to report this first.)

Do the second one, and then paste the last 1000 lines of the console output.

The most likely reason to need a second update is if the database version changed, which it did, earlier this year. Perhaps you just picked up that change.

Update UI not fixed after update error and SSH launcher rebuild

Running for the second time fixed it. Thank you @Ed_S (I had trouble getting the logs from my VPS, omitting since it works now)
