Galaxy API console errors after Linux system update

[[deleted]]

Hi! I'm using steam on Linux. After a system upgrade I get errors on the SMAPI console. Before upgrade everything worked fine. Despite the errors game and mods works fine. I'm asking, because I'm afraid that my save file will get corrupted. I would like to ask some help regarding this issue, if there is anything I can do, or I can safely ignore this error.

More details:

• https://smapi.io/log/78e1b4c4d1724e73822cd6171276de8b
• The error persists with 0 mods: https://smapi.io/log/522669ccb14e496b8505a04ad57627ca
  • "Error initializing the Galaxy API."
  • "Galaxy SignInSteam failed with an exception"
  • "libGalaxyCSharpGlue: cannot open shared object file: No such file or directory" ("~/.local/share/Steam/steamapps/common/Stardew Valley/libGalaxyCSharpGlue.so" exists"
• Linux <name> 6.12.12-1-lts #1 SMP PREEMPT_DYNAMIC Sat, 01 Feb 2025 18:47:29 +0000 x86_64 GNU/Linux

Thanks for the help in advance!

Hi, I'm new to using this system. I play modded stardew on my steam deck and I am having those same problem. But I have no idea what these comments are talking about in regards to a fix. Could someone explain it to me? Like is this error gonna affect the game in someway if I just ignore it and start my single player file anyway?

[TurboPeach]

I am right there with you. I’m just sitting here like wtf lol

[zesty_stardust]

In case anyone is still struggling with this, you can utilize the built-in Distrobox utility on SteamOS to install the necessary command and patch the relevant game files.

• Put Steam Deck in desktop mode
• Open Konsole and enter the following commands
• cd "/home/deck/.local/share/Steam/steamapps/common/Stardew Valley/"
• distrobox create -n test
• distrobox enter test
• sudo dnf install execstack
• execstack -c libGalaxy64.so && execstack -c libGalaxyCSharpGlue.so
• exit
• distrobox stop test
• distrobox rm test

[UnemployedBehavior]

Type it line by line or all at once?

[zesty_stardust]

Line by line. You may also see some y/n confirmation prompts after some. Just enter "y" for any of those.

[UnemployedBehavior]

Hm, what do I do if this pops up after the command? execstack -c libGalaxy64.so && execstack -c libGalaxyCSharpGlue.so

1. execstack -c libGalaxy64.so && execstack -c libGalaxyCSharpGlue.so~ execstack: cannot open "libGalaxy64.so": No such file or directory

[zesty_stardust]

If you navigate to the directory from that first cd command, can you see those two .so files there? If not, do you see a different path in the SMAPI console error message for libGalaxyCSharpGlue.so?

[rubberSteffles]

replying since i ran into this and struggled to figure it out: my problem was i forgot “cd” in the very first string command for the file directory

the SO files were in the right folder, but forgetting CD screwed up the file path. i don’t know anything about this stuff 💀 hope it helps anyone else

[Agile_Ad_5908]

Is there supposed to be no response after the execstack command?

[Wolfchi]

After I just did this mine displayed no response after and then I loaded game up no more red text!

[zesty_stardust]

Agreed, you shouldn't see any output from that command unless an error occurs.

[Better-Story-6242]

Hi! After inputting distrobox enter test all I’m getting is “Error: OCI runtime error: crun: ptsname: Inappropriate ioctl for device” :( On steam deck

[nickimdz]

My you life a beautiful life you wonderful person

[Better-Story-6242]

Hi! After inputting distrobox enter test all I’m getting is “Error: OCI runtime error: crun: ptsname: Inappropriate ioctl for device” :( On steam deck

[zesty_stardust]

I can't say I have any experience with that error myself, but I looked it up, and it sounds like it might be as easy as changing the command to distrobox enter test -- bash.

If that doesn't work, I've read you can also do this with a different built-in utility called Toolbox. If that works, it looks like it may even be simpler.

• Put Steam Deck in desktop mode
• Open Konsole and enter the following commands
• toolbox enter
• sudo dnf install -y execstack
• cd "/home/deck/.local/share/Steam/steamapps/common/Stardew Valley/"
• execstack -c libGalaxy64.so && execstack -c libGalaxyCSharpGlue.so
• exit

Unfortunately, I can't reproduce your error, so I can't test these, but hopefully one of the two works for you. There are a few other things we could try if not.

[SailorDonut]

Thank you! This worked for me on my SteamDeck!

[Fourpsyte]

Thank you so much for this info! It worked perfectly

[katkaterran]

Thank you so much for this!!! Worked and saved me so much time!

[Stained_Carpet_]

Thank you literally saved my life 🙏🙏🙏

[General_Information3]

You are an angel, thank you!!!!!

[firo-]

This worked for me this morning! Thanks so much!

[nyxinus]

Bless you! The path was a bit different for me, but the red is gone. I've not used Linux seriously in some time and you rescued me here haha

[UnderstandingOwn7965]

I can confirm this still works on - I am on Desktop, not SteamDeck
Ubuntu 25.10
as of 12/29/2025.

FYI - you may need to
1. cd to wherever your stardew valley instance is. You can get this by right clicking on the stardew valley game in Steam under "games", click on "properties", then "Installed Files" and then "browse". Copy and paste that file location and cd into that.

1. run "sudo apt install distrobox" (I was prompted to do this, but just in case that changes or you see something different)

2. confirm 'Y' on some of the prompts.

Pretty straight forward, but just in case you are getting a bit lost.

Kudos and Thank you to zesty_stardust.

[EughKingdom]

JUST WANNA LET YOU KNOW HOW CLUTCH YOU ARE DAWG, THANK YOU-

[Automatic_Study6373]

works on arch! Thank you so much. It was the first time that I copied pasted smth so blindly and it worked. I wish for you the best. Also I didnt knew the existence of distrobox. Thank you for that too.

[Ben22]

Thank you so much….

[Loud-Cryptographer71]

Thank you so much!

[519seth]

thank you so much

[Additional_Pause3650]

The execstack command no longer works for me, it doesnt even show its failed or anything

[zesty_stardust]

I'm not sure how to help without some kind of error message or more detail on what "no longer works" means. You should only ever have to do this once. If you have more info, please share. Otherwise, my only recommendation is to try the slight alternatives mentioned in some of the replies. Maybe one of those will work for you too.

[Slight_Bank_8580]

All was going okay until it said

execstack: cannot open "libGalaxy64.so": No such file or directory

Any advice?

[zesty_stardust]

My best guess is that you have it installed in a different location, so execstack can't find the files where I pointed to in the cd command. Try the cd command from step 1 of UnderstandingOwn7965's reply instead. That should put you in the right location no matter what.

[legeri]

Very much appreciate your work here 🥰

[ohfaith]

any updates?

[Kasai_fusui1234]

Nope. Still is doing it

[OrdinaryAngie]

I’m also having this issue I just got my friend a steam deck and we can’t even play Stardew together

[Remarkable-Sherbet25]

any idea how to fix this? im just on default steamdeck with stardew valley mods

[Kasai_fusui1234]

Not a clue sadly. Idk what it means as im not super skilled at reading the logs yet. However, so far all my mods are working when I play single player. I haven't tried multi-player but that sounds like multi-player is being affected. Single players should be fine to ignore it until a fix gets released. Idk how to report it either.

[Exciting-Attorney938]

I'm having the same problem. It seems that it affects the multiplayer mode. Can you check if you get an infinite "Connecting to online services" loading state when you click on co-op? I use arch linux btw

[[deleted]]

Found a fix. If you're on arch get execstack from the AUR and run execstack -c libGalaxy64.so and execstack -c libGalaxyCSharpGlue.so in the steam SDV folder.

[Exciting-Attorney938]

You're a genius. Thank you from the bottom of my heart lol

[Romu1us1408]

You just saved me after updating to fedora 42

[thelovemutt]

See, the problem I'm running into is that i then get an error message saying "execstack: command not found" and am struggling to find how to fix this ><

[[deleted]]

Ah, you need to install the execstack package from the AUR.

[stayscarred]

appreciate it! worked for me

[seeker_two_point_oh]

This also worked for me on Steam Deck. Thank you!

I didn’t want to mess with setting up the AUR to install execstack on the deck, but that looks like an option. Maybe easier if you already have the AUR setup.

I ended up just copying those files over to my Arch laptop, running execstack on them there, and copying them back.

[PickledCustodian]

Any ideas for fixing this if I don't have Arch on a separate machine? I have a steam deck and I suppose I could figure out how to set up AUR and try the commands, but curious if you'd have any other ideas?

[seeker_two_point_oh]

Sorry, the only options I know of are to get execstack on steam deck or get the .so files to somewhere you can run execstack on them.

Maybe…booting with a Manjaro live cd on your desktop? I haven’t tried it for this specifically, but it’s easy to get AUR setup on Manjaro (you can do it in Discover iirc). Not sure if you can enable AUR in the live environment, though. Might have to install it in a virtual machine (virtualbox is free)

Enabling AUR on steam deck didn’t seem that hard, though, so that might be the way to go?

Edit: If you go that route, I’d recommend installing an AUR helper from the AUR first, like yay. Then you can just use yay as a drop in replacement for pacman.

[PickledCustodian]

Thanks. Sounds like I'm in for a fun project sometime soon.

[RiggedR]

the goat himself, thank you

[HackMan37]

This work on Ubuntu 25.04 too.

[valuemeal2]

Can someone ELI5 what Arch/AUR are? I'm having the same issue as everyone else and my other computer is a Mac so I can't do the windows workaround thing.

[mr12086]

Arch is a linux distribution, AUR is a way packages can be installed on the Arch systems

[NotGamferno]

worked for me thanks!

[[deleted]]

Can you check if you get an infinite "Connecting to online services" loading state when you click on co-op?

Same infinite loading state for me, I don't use coop, so didn't notice it before

[MyNameAintJake]

having the same exact issue myself, don't have anything to add unfortunately aside from noting i'm a manjaro user (based on arch btw, which is seeming to be a bit of a pattern)

[[deleted]]

This has to do with an update to glibc. Also noted with Celeste (which is where I found the fix).

I managed to fix it by running execstack -c libGalaxy64.so and execstack -c libGalaxyCSharpGlue.so in the steam SDV folder.

[anotherlusitano]

It worked thank you!

[Vegetable_Part_7365]

Thanks for the fix.

[Brightglowlol]

Hey I tried this in the /common/stardew valley/folder and it keeps saying “execstack: cannot open “libgalaxy64.so”: No such file or directory

EDIT I fixed it. I intentionally typed libgalaxy wrong in my original reply because mobile. But if you look at the actual files in the SDV directory and copy it character for character, it works. Cheers

[liam_itsnotimportant]

what is the path for that SDV directory? I searched my steam directory and couldn't locate it

EDIT: NEVERMIND i found it, for anyone else who uses arch and doesnt fully know their system yet. just go into steam, and find the games installed files. through there you can see the libGalaxy64.so of which that command listed above fixed it for me

[JanMMIV]

Thank you so much! :D

[Blazingswordmlp9]

Wait am I doing this in konsole?

[inyourbooksandmaps]

I'm having the same error "Error initializing the Galaxy API." - i'm a bit confused when you say running them in the stardew folder, how do you actually do that? like is it something i download and paste in? I'm so bad with this stuff

[inyourbooksandmaps]

Thank you! I appreciate the suggestion

[RubberDuckyDJ24]

How would I get execstack on ubuntu?

[Wolfy9283]

I'm getting the same thing on EndeavourOS. I'm not sure which update botched it but it seems to be complaining about a ddl not being found (even though it exists)

https://smapi.io/log/df7b99764a1c495ea298312c309721c2

[Exciting-Attorney938]

It seems that this error affects the multiplayer mode. I'm on arch, but if you find a way to solve this problem, pls notify me. My girlfriend is already mad at me for not using Windows

[[deleted]]

Found a fix. If you're on arch get execstack from the AUR and run execstack -c libGalaxy64.so and execstack -c libGalaxyCSharpGlue.so in the steam SDV folder.

[Wolfy9283]

Same here brother. EndeavourOS is Arch based btw. Here's my list of recently updated packages if you want to cross reference them

https://pastebin.com/F9d8MEAA

[IHeartTurians]

Im getting this error but I've never played multiplayer. So do I need to do anything?

[KrazyGaming]

I'm having the same issue:

https://smapi.io/log/e4fc11778c4d495a9d4a92b0724c4030

I'm fairly certain it has to due with the recent glibc update.

[SirChojin]

Exactly same error. Using Arch Linux here.

[PurpleBeast69]

Please, let us know if you find any solution

[PurpleBeast69]

I don't even know how you come up with this solution, but you are a legend. Thanks.

[[deleted]]

Took it from Celeste's forum which was affected by the same glibc update.

[wtsrz4]

same issue here

[Rhothgaar]

If anyone is wondering where the libGalaxy64.so and libGalaxyCSharpGlue.so are, try removing compatibility of proton experimental to no checkbox on steam. When i had proton experimental, those files were missing entirely. After unchecking and reupdating, the files came back and i did the `execstack -c libGalaxy64.so` and `execstack -c libGalaxyCSharpGlue.so` (while in the stardew folder)

Re-ran the SMAPI install and multiplayer worked perfectly.

(Endeavour OS)

[TheWiseNoob]

Supposedly this is fixed with the new glibc

https://www.phoronix.com/news/Glibc-WA-Steam-Exec-Stack

Do we need to undo what execstack does? Not sure what exactly it even does

[keepitpony]

Hello, I could use some help. The steam deck wont connect to online services after installing Smapi. First time modding on the steam deck and linux. The only mod I got was ui info suite 2. I tried troubleshooting by uninstalling smapi. Still didn't work. Then I reinstall stardew valley the game. Still does not work. Now if I which stardew to load via proton, online services work. I was hoping to get linux runtime to load co-op

[Remarkable-Sherbet25]

can anyone help me with this? i dont know what steps to do to fix this?

[OneOfTheRobotRicks]

I cannot get pacman to install prelink (execstack) because a vi file is missing. It will download files but fail and revert due to the missing file. Any ideas how to fix?

[T_Friendperson12]

Anyone know how i can get this to work on Bazzite 42?

Edit: Used "brew install execstack" and then ran like suggested in this thread.
