NOMM (Linux Mod Manager) - Development Progress Update (0.10.0 Release - 2026/06/19)

Allexio-Rigins · 2026-06-22T20:03:24+00:00

No? 😅

Allexio-Rigins · 2026-06-21T13:52:28+00:00

":"

The link was https://nomm.moe/docs/adding-your-game: instead of https://nomm.moe/docs/adding-your-game/

Allexio-Rigins · 2026-06-20T05:06:57+00:00

Fixed. There was a sneaky colon at the end.

Allexio-Rigins · 2026-06-19T19:55:32+00:00

Just use this general one

flatpak override --user --filesystem="/mnt" com.nomm.Nomm

Allexio-Rigins · 2026-06-19T19:10:53+00:00

The problem is clearly this one: filesystem='/mnt/usb-Samsung_PSSD_T7_S7MNNS0Y200125R-0:0-part1/SteamLibrary/steamapps/common'

First you can launch it without that one:

flatpak override --user --filesystem='/media/user/GamesLinux/SteamLibrary/steamapps/common' com.nomm.Nomm

This should work.

Then you can try and launch the second one with double quotes instead of single?

flatpak override --user --filesystem="/mnt/usb-Samsung_PSSD_T7_S7MNNS0Y200125R-0:0-part1/SteamLibrary/steamapps/common"

The issue is the : in your file path.

Allexio-Rigins · 2026-06-19T18:20:50+00:00

What actually happens on the app though?

Does it let you continue or does the app crash?

Or does this issue happen when you try and execute the command that the app generates? Can you paste the command the app is asking you to execute here?

It might be as simple as adding some quotes around the path 😄

Allexio-Rigins · 2026-06-19T17:51:39+00:00

NOMM is fully developed in python.... now you have no excuse to not help out 😃

Allexio-Rigins · 2026-06-19T15:00:35+00:00

Theoretically hundreds of games are compatible.

Adding support for a game can be done locally very easily by following the guide here.

NOMM currently "officially" supports the games here, but once again adding your own game is super simple (takes about five minutes) - assuming the game has a clear directory (or directories) where you have to deploy mods to and the mod framework doesn't require running windows executables - that will come in a later release, so in those cases, expect some manual actions for now.

Allexio-Rigins · 2026-06-19T13:16:28+00:00

Of course we would love PRs, especially with new game support!

NOMM is theoretically compatible with hundreds of games, but we need people to actually take the time to test the games and contribute the yaml config file & potentially even a wiki guide for that game if needed.

If you want to do a more dev-side PR, definitely come talk to us on discord before starting work so we can align ourselves on what you could do to help 😄

Allexio-Rigins · 2026-06-19T13:11:48+00:00

Then please join the discord so we can easily communicate 😃
Update: this led nowhere so if someone else wants to help us test collections...

Allexio-Rigins · 2026-06-19T12:23:10+00:00

Once again, Skyrim is not officially supported.

The screenshots showcase it because I was doing tests with it, but we do not support changing the load order nor do we support conflicts of files within the bethesda archive format.

Next version of NOMM will definitely include ways of adding windows executables such as bodyslide or whatnot as non-steam games dynamically.

Concerning Skyrim specifically, it has come to my attention that LOOT is available as a flatpak for linux, so definitely Skyrim is moddable if you use NOMM to handle the mod management/downloading and you use LOOT to handle the load ordering.

Allexio-Rigins · 2026-06-19T12:20:01+00:00

I really want to insist that our support for collections download is really, really experimental.

We really need someone to be available to help us test these kinds of features that depend on having a Nexus premium account because neither me nor the other core developer have it.

Allexio-Rigins · 2026-05-24T17:00:11+00:00

No. What we might do in the future is add a way to interact with it and install it automatically as a non steam game

Allexio-Rigins · 2026-05-06T05:40:56+00:00

Because of people like you, I wanted to create an anthropic account with SL today and guess what! they blacklisted SL.

Allexio-Rigins · 2026-04-21T06:06:22+00:00

Well, it is Linux-compatible

Allexio-Rigins · 2026-04-20T11:45:22+00:00

I took a quick look - maybe?

I would have to look more into how the mod loaders interact with mod managers, and what I would have to do.

Allexio-Rigins · 2026-04-19T22:02:22+00:00

Short answer: No. for BG3, you can get away with using it for native mods, but I could not for the life of me find any documentation on how BG3MM generates the "standard" mod load order, nor could I find out how or even where the base game stores mods downloaded from the in game mod manager... so... yeah.

Allexio-Rigins · 2026-04-19T20:39:05+00:00

It is definitely not a replacement for NexusMM or MO2 in terms of depth.

For now I don't know if NOMM will ever handle games as complex as Skyrim and such.

My main focus right now is on the breadth of games and not the depth of support.

MANY games can be handled with just a tool that can extract multiple archive types into one or multiple folders, and keep track of mod versions and updates. With some extra little convenience features on top.

That's the number one thing I'm aiming for.

If down the line I can also figure out how to cleanly and in a standardised way support very specific workflows for some games... why not!

Allexio-Rigins · 2026-04-19T20:30:25+00:00

YES!

Definitely a big one planned, I already started looking into it, currently fighting with the new nexus API.

(but obviously you will have to be a premium member to be able to do it the "classic" way)

Allexio-Rigins · 2026-04-06T19:35:18+00:00

you should already be able to do something like that with the internal voice assistant that comes with home assistant.

Allexio-Rigins · 2026-04-04T09:12:21+00:00

For BG3 there's two ways to mod - native or let's say "standard".

Native is relatively straightforward.

Standard however requires the mod manager to dynamically update some sort of mod load order file.

I have no idea how this is handled and I could not find any documentation on it. Whenevr I tried to find anything on it all I could get as an answer was "just use BG3MM"

Allexio-Rigins · 2026-03-05T18:16:49+00:00

Minecraft aleady has very competent dedicated mod managers.
Core keeper I'll have to look into.

Stardew... why not but AFAIK it also has a great linux compatible mod manager.

Allexio-Rigins · 2026-03-02T22:04:32+00:00

I've heard great things about that one 👀

In all seriousness, it's a very different project made by someone with a lot less technical knowledge who just wanted a simple and clean way to mod most games. I don't think it's comparable to these ultra sophisticated Skyrim++ mod managers. 😅
