UGC Workshop addons | Scan failure - Failed to Download (Linux Issue)
Hey there everyone, hope ya'll are doing well
I had posted this issue in the github, but I've decided to post it here too, in hopes that someone from here knows how to fix it (if possible, anyways)

So, when trying to download maps that use the new UGC, it bugs out, throwing the following error in the console:
No output data for Entity [472][jazz_hub_selector] (JazzForward_OnMapDownloaded)
I have tried running this gamemode through both the flatpak and system versions of Steam, tried using multiple different Proton variants, the 64bit beta of GMod, even tried to use the github version of the addon, but nothing seems to work

Does anybody have any leads on what could be causing this error, or at least how to fix it? Thanks in advance

(Ps. the only addon I had installed was this one, so it most likely isnt an addon conflict thing)

Have you tried on this github version? https://github.com/SageJFox/jazztronauts/tree/sceneroots
Just tried it, unfortunately, same error comes up, although a different entity ID is causing the problem, here's the console output:

DownloadGMA_Dedicated FAILED: Specified addon uses the new UGC workshop system, which is not compatible Using fallback, DownloadGMA_Listen Download workshop addon 3208328859 on client via DownloadUGC Finished steamworks.DownloadUGC - S:/workshop/content/4000/3208328859/gmpublisher.gma Client finished with download file: S:/workshop/content/4000/3208328859/gmpublisher.gma Addon downloaded, decompressing and mounting... Mounting: 1.3500000022759e-05 seconds. No output data for Entity [601][jazz_hub_selector] (JazzForward_OnMapDownloaded)

I tested it using the newest GE-Proton and the 64 bit version of GMod, I'll try some other configurations and see if that makes any difference

This second console log gave me an idea of what the problem might be. I've put in a prospective fix, but not having the issue myself I have no idea if it works for this (I just know it doesn't break my downloads :p ). I'd ask that you get the latest push to the sceneroots branch and try again.
Hmm, still throws the same error, tried on some different proton versions and still nothing, so that's probably not where the issue lies; Is there any way I can provide a more "complete" version of a log? Maybe that could help you figure out where the problem stands

Ps. The error code is still the same, "No output data for Entity [601][jazz_hub_selector] (JazzForward_OnMapDownloaded)"

That's unfortunate, but it was a bit of a long shot. Unfortunately, I'm out of ideas at present. Meant to mention it before but the entity number changing there was just from the bar map being updated. The more pertinent information is what was before that.

Where is your Steam directory installed, and is your GMod in an alternate directory compared to it?

I had this issue as well and here were a few things I noticed:
  • It only happened when using Proton (native Linux / Windows worked fine)
  • Old workshop addons that weren't gma files loaded fine.
  • The gma file was successfully downloaded each time and existed on disk.
  • Mounting took neglible time and returned nothing usable for Jazztronauts. (It didn't display "CONTENT MOUNTED!!!" in the console like it does when it succeeds)

There's a bit more discussion about it on Github. [github.com]

I have 2 places I usually store my steam games at, those being my root, standard folder and a "Games" folder on my second drive (that steam should have full access of). I have tried running GMod on both, but nothing changed (I did assume it maybe just wasn't reaching the mods, but considering it does install the files...idk)

I'm agreeing with the idea that it's an issue with GMod's implementation of mountGMA on Linux. The negligible time would seem to be because mountGMA is bailing out immediately.

Part of my test was that I tried loading up the same addon SkullDollar reported, and then later reran it while intentionally breaking the filepath on my system. The successful mount took about 100 x longer than the bad path mount attempt for me.
If this is caused by Gmod's implementation, there's probably nothing we can do, which is unfortunate, but not unforeseeable of that being the case
idk but now its not working for me
