I am trying to install steam on my Rocky 8.10 using flatpak. I was initially following this guide but I received an error when launching steam.
The unofficial Steam Flatpak app now requires user namespaces to be
enabled.
Check that the bubblewrap executable used by Flatpak, usually
/usr/bin/bwrap or /usr/libexec/flatpak-bwrap, is not setuid root.
If the file /proc/sys/kernel/unprivileged_userns_clone exists, check that
it contains value 1.
If the file /proc/sys/user/max_user_namespaces exists, check that its
value is at least 100.
For more details, please see: User namespace requirements · flatpak/flatpak Wiki · GitHub
I checked the bubblewrap and it seems correct, -rwxr-xr-x. 1 root root 71296 Sep 5 08:30 /usr/bin/bwrap.
The file /proc/sys/kernel/unprivileged_userns_clone does not exist.
Lastly, /proc/sys/user/max_user_namespaces contains 254986.
Any help would be greatly appreciated. I am using Flatpak 1.12.9 - app/com.valvesoftware.Steam/x86_64/stable v1.0.0.81.
