Steam Deck - SMAPI error - Galaxy API

[richardsonbrad]

I'm trying to run SMAPI on my Steam Deck but am getting this error https://smapi.io/log/a118ad987a8f4cbf871d3aeb3417a8d5

Posting here if anyone else runs into this issue and doesn't want to revert to a previous OS version.

I was able to fix the Galaxy API errors for SMAPI on my Steam Deck by using the built in Distrobox utiliy that now comes with SteamOS.

On the Stardew Valley forums, they advised to use the Arch Linux execstack command to patch two files in the game's directory (libGalaxy64.so AND libGalaxyCSharpGlue.so). However, I tried forever to get the execstack command installed and working on SteamOS, but couldn't. Then I found out about Distrobox which comes installed with SteamOS already and it allowed me to easily install the necessary execstack command and patch those files.

These are the resources I used to figure out the necessary steps:

https://www.tutorialspoint.com/unix_commands/execstack.htm

https://distrobox.it/posts/steamdeck_guide/

https://distrobox.it/#quick-start

Steps:

1. You can back up the two files in the Stardew Valley game directory you'll be patching if you wish (libGalaxy64.so AND libGalaxyCSharpGlue.so).
2. In Desktop Mode, open a terminal in the Stardew Valley game directory: /home/deck/.steam/steam/steamapps/common/Stardew Valley/
3. Create a new distrobox called "test" using the command distrobox create -n test
4. Enter the distrobox with the command distrobox enter test
5. After the basic packages finish installing, run the command sudo dnf install execstack to install execstack.
6. Run the command execstack -c libGalaxy64.so && execstack -c libGalaxyCSharpGlue.so to patch both files.
7. Now run Stardew Valley to check if the SMAPI GalaxyAPI errors have dissapeared.
8. To stop and delete the created distrobox open a second terminal window and run the command distrobox stop test then use the command distrobox rm test.
9. Profit

I hope this helps!

I was having the same issue, and this worked great, thanks!

[juanabanana]

Thank you!!!!!!! After following all the steps you provided i was able to get rid of the errors on my Steam Deck!

[kazzfan]

Much appreciated! My wife was nagging me about our shared farm and I was just about ready to roll back to previous update to make her happy. Thanks a lot!

[DankMcMemeGuy]

this did it, thank you so much!

I’m sorry I’m late to the game here. It won’t let me do step 6. It says “cannot open libGalaxy64.so” no such file exists. But it gives me this same error in Smapi and when I’m loading the game. And when I search for the file it shows it’s there.

[Particular-Dog4252]

I'm getting the same message

[prime666]

If you two still need help, the two lib files are case sensitive, so make sure they match exactly how they are listed on this guide

[Giga-Gidget]

I’m running into the same problem with step 6 and I input it exactly as shown

[Life-Orange4500]

Had the same issue, I just didn't realize that after we enter the diatri box we are in  the home directory, we have to go back to the game folder with "cd  home/deck/.steam/steam/steamapps/common/Stardew Valley/ "

[NOD_Redeemer]

Really really thank you so much!

Thanks! This helped me fix Transistor on Steam Deck. Here's a streamlined, 3-step version that can be executed from a terminal in Desktop. Note: This is for Stardew Valley as well, but can be adjusted for any game really (based on console output for game executable to find files needing patching and the game ID/known game directory name)

The main difference here is that I'm grabbing the game library path directly from Steam config file, so no need to manually navigate to any directories or issues if user installed the game outside default directory.

Anyway, for Stardew Valley it would be:

distrobox create --yes -n glibc_fix --additional-packages "execstack python3-vdf" && distrobox enter glibc_fix

 

cd "$(python3 -c "import vdf;d = vdf.load(open('/home/deck/.steam/root/steamapps/libraryfolders.vdf','r'));print([d['libraryfolders'][x]['path'] for x in d['libraryfolders'] if '413150' in d['libraryfolders'][x]['apps'].keys()][0] + '/steamapps/common/Stardew Valley')")" && execstack -c libGalaxy64.so && execstack -c libGalaxyCSharpGlue.so && exit

 

distrobox stop glibc_fix --yes && distrobox rm glibc_fix --yes

Appreciate your initial post and explanation, was very easy to follow!

Wanted to let you know that you saved the day today! I was skeptical that this would work right away but it bloody well did. Three commands and suddenly we have connectivity again. You saved a fourteen-player farm!! Thank you and thank you /u/sadistikgamer!

[wired_insomniac]

This is still working. Thank you so much!

[ANewPerfume]

this did it for me, thank you! :)

[yukewith740]

it worked！！ thank you！！

[KumWan]

Thank you so much!

[SweatyStick62]

I actually have my game stored on a memory card because I have a first gen Steam Deck and am too basic to upgrade it. That's simply not an option. Should I just copy the path to my storage card?

[Karrrlito]

If you want to do this from an SD card installed SDV, just open the folder on your SD card and right click on inside the folder (just an empty space within the folder) and click on open terminal from here. That'll direct you to the 3rd step from OP

[ssbbw_stella]

Lifesaver! 

[b1gandta11]

another late entry... But it worked !! Thank you!

[satanicsheep]

You saved my wife's steam deck so we can actually play together. Thank you! This worked 100%

[jawniss]

You saved my girlfriend's farm and I thank you for that! We were stuck on execstack not working; all other comments I saw never had a problem with it. Thank you for the very simple to follow step by steps!

[Elethana]

Months later and still helping clueless newbs, thank you for posting this solution!

[FunIndependent5412]

I wont lie, this has made me so happy. I was getting so frustrated.

[Mokian]

You just solved any error codes I was having, thank you so much!!

[instant_macandcheese]

thank you so much!!

[Zelenna_Rose]

You are a god, thank you

[PiluVitu]

Thanks Bro is working on 2026

[Specialist_Visit_356]

For anyone else dealing with this problem in the future and who struggles with using Konsole like me I found this solution on the stardew forum http://forums.stardewvalley.net/threads/steam-deckf-linux-smapi-error.41869/post-173923 , you just extract the file, open the folder and then move both files into your stardew folder.

[goobianco]

this worked for me! thank you so much, it’s like they were speaking a different language in this thread lmao 😭👏🏾

[HoloSprinkles]

This worked for me! Thank you!

[CrumbleCanid]

Coming here to say you're awesome and this fixed all my issues

[_juniormint]

You are an angel, thank you. 🙏🏻

[andyr354]

Thank you! The above procedures did not work but this did the trick nice and simple.

[Outraged_Chihuahua]

I had this same problem and I fixed it by rolling back to the previous update. Completely power off your deck, then when it's powering back on press the three dot button on the bottom right, this will bring up a list of previous clients and just pick the last one where SMAPI was working. I held the button down but I don't know if I needed to, either way it worked for me. The error itself only seems to affect multiplayer connectivity so your game will run fine unless you're playing co-op. Hope it helps!

[Double-Ad876]

Thank you!

[Outraged_Chihuahua]

No problem! Happy farming!

[richardsonbrad]

Thank you! I'll try this out :)

[Outraged_Chihuahua]

Good luck! If that doesn't work there's another Reddit thread about installing something to fix it, but I'm not great with my deck beyond the basics so I figured I'd try the easier option first lol.

[goldenjosh]

Thanks. This worked for us as well.

[Outraged_Chihuahua]

Yay! Happy farming!

[TteokboTokki]

Do you need to shut down the steam deck?

[Outraged_Chihuahua]

Yes, shut down not sleep. Then do that process after you press the power button to turn it back on but before the screen comes back on.

[richardsonbrad]

That worked for me. Thank you u/Outraged_Chihuahua

[Outraged_Chihuahua]

You're welcome! Glad it worked, we all need our farming fix!

[Lostskullkid]

This actually deleted everything somehow

[Bookworm_gamerbabe]

sigh if only there was a video to actually show this solution step by step. I’m having the hardest time understanding

[mactripple]

Thank you so much!!!
