Install server updates

The Updates tab lists the plugins, mods, datapacks and Bedrock packs on your server that have a newer build. It covers what you installed from the marketplace, since we know where each of those came from. Files you uploaded yourself are not checked.

• The server software and a modpack are not listed here. Move those to a new version under Server software on the Software tab, as Change the server software describes.
• On a server someone shared with you, installing an update needs the Install software permission.

1. In the dashboard, go to Container Apps and open the server, then the Updates tab.
2. Read the list. Each row shows the Package, the Current build on the server, the build that is Available and the Source it comes from.
3. To check again, select the refresh button next to the title.

We only offer a build that fits the server's software and game version. We prefer release builds over beta and alpha builds, and offer a build only when it is newer than the one installed.

The Install and Install all buttons on the Updates tab do not work at the moment: they fail with Could not queue the update. Install updates from the Software tab instead:

1. Open the Software tab, then Installed addons.
2. Find the addon. A row with an update shows a badge that names the new build, for example Update to 2.11.0.
3. Select Update on its row.

We remove the old file and install the new build as a job, which the Software tab follows. The new build loads the next time the server starts. Manage installed addons has the details.

When every tracked addon is on its newest compatible build, the tab shows Everything is up to date.

Could not queue the update

The buttons on the Updates tab fail at the moment. Update the addon from Installed addons on the Software tab.

Could not check for updates

We could not reach a source to compare builds. Select Try again, or check again later.

An addon you installed is missing from the list

The list shows only addons with a newer build that fits your server. A file you uploaded yourself, or copied in with an import, is never checked.

• Manage installed addons
• Install plugins, mods and modpacks
• Change the server software

GET /api/v1/client/servers/{uuid}/updates returns {"updates": […]} with one entry per addon that has a newer build:

{
  "updates": [
    {
      "record_uuid": "3f2c8a61-0d4e-4b7a-9e15-6a2b7c9d0e41",
      "display_name": "LuckPerms",
      "kind": "plugin",
      "source_name": "Modrinth",
      "install_path": "/plugins/LuckPerms-Bukkit-5.4.141.jar",
      "current_version": "vKq6e7Sf",
      "current_version_name": "5.4.141",
      "latest_version": "Rk3eYx1m",
      "latest": {"version_id": "Rk3eYx1m", "name": "5.4.145", "release_date": "2026-09-12T08:30:00Z", "version_type": "release"},
      "update_available": true,
      "checked_at": "2026-09-25T14:30:00+00:00"
    }
  ]
}

current_version and latest_version are the source's own build ids, and current_version_name and latest.name are the version names people read. To install an update, send POST /api/v1/client/servers/{uuid}/software/{record_uuid}/update with the entry's record_uuid, as Manage installed addons shows. GET /api/v1/client/servers/{uuid}/software/updates gives the same check with more options.

Any user on the server can read the list.
