[SOLVED] Games that use Steam Linux Runtime 1.0 (Scout) fail to launch

When trying to run games with a Linux version, they will fail to launch with the error "Compatibility tool failed". When forcing the compatibility tool to use Steam Linux Runtime 1.0 (Scout), it will fail with the same error. A consistent test bed that I've been using for this is Aperture Desk Job.

Steam Linux Runtime 1.0 (Scout) will not install, as the install button is greyed out. Trying to validate the files returns "All 0 files successfully validated".

I launched Steam via the terminal and then tried to launch Aperture Desk Job, and this was all of the output in the terminal:

Re: [SOLVED] Games that use Steam Linux Runtime 1.0 (Scout) fail to launch

Have you tried our lord and savior flatpak? There's steam on flathub and it just works, doesn't need almost anything from your system (it's isolated, like a container).

Otherwise, according to wiki, you'll need to have multilib enabled, 32-bit graphical drivers and some other stuff. On the wiki there's also section on using debugger with steam. The .dmp file you uploaded - if you use gdb like wiki says and then backtrace command when it crashes, you should be able to extract some information in text form.

Re: [SOLVED] Games that use Steam Linux Runtime 1.0 (Scout) fail to launch

I originally was avoiding using Steam on flatpak due to places saying that it's unofficial and also has it's own quirks. I will keep this in mind as a last ditch effort though, and appreciate it.

Multilib is enabled, and 32-bit graphics drivers have been a constant  hell for me if you've seen my other posts by chance, so any suggestions there too might be worthwhile.

Now using https://wiki.archlinux.org/title/Steam/Troubleshooting, I first used section 2.2, using this:

$ cd ~/.steam/root/ubuntu12_32
$ file * | grep ELF | cut -d: -f1 | LD_LIBRARY_PATH=. xargs ldd | grep 'not found' | sort | uniq

Unfortunately I didn't save the original results, but was missing about 8 files. I went thru the Arch Repositories and got every 32-bit and regular version of the ones I could find, and reinstalled the ones that were already installed. I couldn't find one last file though, which I will show here:

[Ashley@SelPC ~]$ cd ~/.steam/root/ubuntu12_32
[Ashley@SelPC ubuntu12_32]$ file * | grep ELF | cut -d: -f1 | LD_LIBRARY_PATH=. xargs ldd | grep 'not found' | sort | uniq
        libgtk-x11-2.0.so.0 => not found
[Ashley@SelPC ubuntu12_32]$ 

After another pacman -Syu and reboot for good measure, the game still failed to boot to the same error. So I started the debugging like you suggested. To make sure that I don't leave anything out accidentally, I've posted the full output of GDB in Konsole here:

Unfortunately I'm not sure what to do with this information, but I hope I was thorough enough with what I could do on my end so far.

Re: [SOLVED] Games that use Steam Linux Runtime 1.0 (Scout) fail to launch

OK, how would you feel about nuking your whole steam directory? You can either create a new fresh user account and test on that, or move / rename .steam directory in your home.

You will need to login again, you will probably lose savefiles, it will have to download games again, and so on. I know it's shotgun debugging but it is also the quickest way to validate if we should look for issues in the system or with the configuration.

I think you can find the last library with `pacman -Fs libgtk-x11-2.0.so.0` and maybe it is worth running a `pacman -Qkk`. Idk.

Re: [SOLVED] Games that use Steam Linux Runtime 1.0 (Scout) fail to launch

I didn't even want to consider your nuclear solution so I went further into trying to solve it myself. I finally got Konsole to redownload Steam Linux Runtime 1.0 (Scout) by deleting both it's app manifest "appmanifest_1070560.acf" in "/home/Ashley/.local/share/Steam/steamapps/" as well as deleting the folder "SteamLinuxRuntime" at "/home/Ashley/.local/share/Steam/steamapps/common/", and finally by running "steam steam://install/1070560" in Konsole. While I had tried that command earlier, it had never done anything or even attempted to download anything. Steam Linux Runtime now properly reports 6 files when validating files, and Steam lets me freely install and uninstall it. Deleting the folder and not the app manifest will not fix the problem, which is why I missed this solution originally.

I realize it's a dumb solution I should have came across earlier, I just try to avoid deleting files as much as I can. Originally I made a bandaid fix, as I brought over the missing SteamLinuxRuntime files from my steam deck, as well as edited the app manifest to report properly which did let me finally launch games successfully, but steam still refused to see Scout as installed. Just noting that down, because I like my paper trails.

As for your last bits of help, oddly "pacman -Fs libgtk-x11-2.0.so.0" gives the error that -s isn't a valid option. -Qkk also would just say that the package was not found.

Re: [SOLVED] Games that use Steam Linux Runtime 1.0 (Scout) fail to launch

pacman -Fs libgtk-x11-2.0.so.0

Sorry, my bad. I was looking for a command to "find which package contains this file". The "-Fs" is 100% wrong and I can't find proper command - perhaps it was something with pkgfile, but that doesn't work for me currently. Anyway:

➜  ~ pacman -Qo /usr/lib/libgtk-x11-2.0.so.0
/usr/lib/libgtk-x11-2.0.so.0 is owned by gtk2 2.24.33-5

So.. just to confirm, do you have gtk2 and / or lib32gtk2?

Steam Linux Runtime now properly reports 6 files when validating files, and Steam lets me freely install and uninstall it. Deleting the folder and not the app manifest will not fix the problem, which is why I missed this solution originall

I am not sure if messing with the "internal" files in the steam directory is a good idea. That's why I suggested removing / moving it and letting steam re-create what's needed. I don't have any solutions for you at the moment; testing it under new fresh user account will answer the question if this is a system issue, or local profile issue.

Re: [SOLVED] Games that use Steam Linux Runtime 1.0 (Scout) fail to launch

I didn't want to mess with the internal files either as I know it's not the best solution at times and can break stuff easily, but I just didn't wanna nuke stuff as i have multiple tools I have setup thru steam for simplicity, as well as various games that just don't have good cloud support. I'll see about those last things you asked about after work.

I will say, originally I also originally couldn't even choose which... branch, i think was the word. Which branch of Scout i wanted, such as Beta and Previous. After my fix, it does let me pick and it even downloads fhe proper files, fully functional now.

Re: [SOLVED] Games that use Steam Linux Runtime 1.0 (Scout) fail to launch

I don't have gtk2 or lib32gtk2. I did solve my issue, it seemed like steam was just dumb for some reason, since it wouldn't let me uninstall or reinstall Scout until i manually removed it myself via the file explorer.
