Linux Galaxy API not loading with glibc 2.41

[JanUwU42]

Could someone write up a step by step guide to fix the so files that can be done in the steam deck desktop mode?

You can try the following:
(Sadly I don't have my Steam Deck on me right now so I cant try it, but thats how it worked on Arch (And SteamOS is based on Arch))

1. Switch to Desktop Mode

2. Open Konsole

3. Install `execstack` from AUR

git clone https://aur.archlinux.org/execstack.git
cd execstack
makepkg -sirc

4. CD into your Stardew Valley folder
(You can find it by going to your Steam Library on Stardew and then Press the settings Button > Manage > Browse local files)
If you have the Flatpack Version of Steam it probably looks similar to this

cd ~/.var/app/com.valvesoftware.Steam/.steam/steam/steamapps/common/Stardew\ Valley/

5. Run `execstack` to fix the problem

execstack -c libGalaxy64.so && execstack -c libGalaxyCSharpGlue.so

I could try it, but I think there was a mention that makepkg doesn't function as intended on the steam deck.

Meanwhile 3.7.9 build of steamos is now available on the beta/preview side, anybody able to test it it has the glibc library bug?

Edit:
There's now a patch released to fix installations of sdv on steam deck
See my post at this thread:

Is it 2026. Is there no non-hack solution to this?

A workaround for the moment is to clear the GNU_STACK program header using patchelf since execstack isn't available on Debian anymore.
While in the Stardew Valley install directory:

patchelf --clear-execstack libGalaxy64.so libGalaxyCSharpGlue.so

Confirmed working in Ubuntu 25.10 with this fix.

There are a lot of replies here, and I can't follow them all...

I'm having a similar problem. Playing with mods on Steam Deck, can't play multiplayer. Switching compatibility to Proton 9.0-4 allows base SDV multiplayer to work, but completely breaks SMAPI - won't launch at all. I would much rather not go without mods over such a stupid bug. If any of the solutions above fixes this, can someone tell me, or quote it in a reply? I'd be mad appreciative, cus I'm at my wit's end. Please and thank you.

Since you have a Steam Deck, the easiest option is to boot into an older 3.6.x version of the OS. For instructions see https://help.steampowered.com/en/faqs/view/1b71-edf2-eb6d-2bb3#menu . Select a 3.6 one (without the “+ boot menu” addition).

Note that this is temporary—the next time your steam deck reboots, it’ll boot into the newer OS, and you’ll have to do the boot menu thing again.

(FYI, here is why the Proton thing breaks SMAPI: you installed SMAPI for Linux Stardew Valley. Using Proton switches you to the Windows version of Stardew Valley, which will not work with the Linux SMAPI setup.)
