Server startup error: Duplicate mod elevated-rails.

[drewmate]

I've been hosting a server based on the factoriotools docker image for several months with very few issues. Today (I think since the 2.0.55 update) it won't start up and gives me the error:

Code: Select all

Util.cpp:81: Duplicate mod elevated-rails.

I've never seen any duplicate errors before, and have been using the same mod-list.json for a couple months at least (I last played on Monday, so I know it worked then)

mod-list.json:

Code: Select all

{
  "mods": [
    {
      "name": "base",
      "enabled": true
    },
    {
      "name": "elevated-rails",
      "enabled": true
    },
    {
      "name": "quality",
      "enabled": true
    },
    {
      "name": "space-age",
      "enabled": true
    },
    {
      "name": "helmod",
      "enabled": true
    },
    {
      "name": "RateCalculator",
      "enabled": true
    },
    {
      "name": "bobinserters",
      "enabled": true
    },
    {
      "name": "flib",
      "enabled": true
    },
    {
      "name": "Cerys-Moon-of-Fulgora",
      "enabled": false
    },
    {
      "name": "Flare Stack",
      "enabled": true
    },
    {
      "name": "PlanetsLib",
      "enabled": true
    },
    {
      "name": "Todo-List",
      "enabled": true
    },
    {
      "name": "VehicleSnap",
      "enabled": true
    },
    {
      "name": "visible-planets",
      "enabled": false
    }
  ]
}

I have inspected the mods folder, and there is only one copy of the mod there

I even cleared out all the mods and restarted the server (and it re-downloaded the above set).

Does anyone know what's going on here? Does it have something to do with the space-age mod and elevated-rails being managed separately? It was my understanding that we needed to list both after the update, but did that change in 2.0.55?

Thanks!

It seems I didn't do enough research... It looks like this is an issue with the docker image:
https://github.com/factoriotools/factor ... 23168e3932

I guess the fix hasn't been pushed to the images yet. Disabling the mods didn't seem to work, so I guess I just need to wait for the images to update.

I get the same error without using Docker, is there a way to solve this? I would like to keep multiple versions of the mod in the mod folder, like you can do with normal mods.

[Rseding91]

The engine specifically errors if a duplicate built-in mod is found since that has historically meant a corrupt install and or failed update.

So no, there's no way to have duplicates with different versions.

Thanks for the reply. I found a workaround by editing the info.json so that one of the mods isn't loaded (insert extra semicolon somewhere).
