• Steam client version (build number or date): I'm not entirely sure, because I can't actually get steam to run through the command or to launch to a real application, but it should be the latest version as of August 25.
• Distribution (e.g. Ubuntu): Fedora 28 (Qube of Fedora 28 on QubesOS R4)
• Opted into Steam client beta?: [Yes/No]
• Have you checked for system updates?: [Yes/No]

Please describe your issue in as much detail as possible:

I installed steam and it launched correctly after I installed it, but it needed to update and the Qube didn't have enough space, so I shut down the Qube and increased the personal storage. When I started the Qube back up, Steam no longer launched from its bash command. Not that much of an issue because I can just run steam.sh. The real problem was that it required dependicies that it hadn't required before. First it just gave: Error: You are missing the following 32-bit libraries, and Steam may not run: libc.so.6 I installed glibc and upgraded related software. After I tried launching steam again and this time it gave this: Error: You are missing the following 32-bit libraries, and Steam may not run: libGL.so.1 libstdc++.so.6 libstdc++.so.6 libstdc++.so.6 libstdc++.so.6 libstdc++.so.6 libstdc++.so.6 libstdc++.so.6 libdrm.so.2 libnsl.so.1 /home/user/.steam/steam/ubuntu12_32/steam: error while loading shared libraries: libstdc++.so.6: wrong ELF class: ELFCLASS64 I was able to install all of those except for libstdc++.so.6 because of a dnf conflict with libstdcxx. I cannot uninstall that and replace it with the correct library because if I uninstall it, it removes basically everything from the whole Qube.

Steps for reproducing this issue:

1. Install the Fedora 28 template for QubesOS with the command: sudo qubes-dom0-update qubes-template-fedora-28
2. Create a new Qube with the template
3. Open the terminal and run su -c 'dnf -y install xorg-x11-drv-nouveau mesa-libGL.i686 mesa-dri-drivers.i686' (for nvidia hardware only)
4. Run sudo dnf -y remove rpmfusion-nonfree-release-28.noarch.rpm rpmfusion free-release-28.noarch.rpm
5. Run su -c 'dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm'
6. Run su -c 'dnf -y update'
7. Run su -c 'dnf -y install steam'
8. Shutdown the Qube and increase the space
9. Power the Qube back on
10. Navigate to ~/.steam/steam/
11. Try running steam (It should give missing libc.so.6 error)
12. Run sudo dnf install libc.so.6
13. Try running steam again (it should give another missing, but this time with different libraries)
14. Run sudo dnf install libGL.so.1 libdrm.so.2 libnsl.so.1
15. Trying to run steam will still give libstdc++.so.6 missing error and you cannot install it without getting a conflict error in dnf between it and libstdcxx. You cannot uninstall libstdcxx without uninstalling a ton of stuff so you're basically stuck in library limbo.
