Unable to build with fresh new install of Fedora 31

[Dimitri2g]

I did a git clone and have been following the instructions and it seems I am failing to build.

I ran:
./steam-runtime/setup_docker.sh --beta amd64 --extra-bootstrap=./proton/steamrt-bootstrap.sh steam-proton-dev

and at the end I got:

Step 8/20 : RUN 	set -xe; 	if [ -n "${proxy}" ]; then 		echo "configure proxy"; 		echo "export http_proxy=${proxy}" >> /etc/bash.bashrc; 		echo "export https_proxy=${proxy}" >> /etc/bash.bashrc; 		echo "export ftp_proxy=${proxy}" >> /etc/bash.bashrc; 		echo "Acquire::http::proxy \"${proxy}\";" > /etc/apt/apt.conf.d/01proxy; 		echo "Acquire::https::proxy \"${proxy}\";" >> /etc/apt/apt.conf.d/01proxy; 	fi; 	if [ -n "${no_proxy}" ]; then 		echo "export no_proxy=${no_proxy}" >> /etc/bash.bashrc; 		oldIFS="$IFS"; 		IFS=","; 		for nope in ${no_proxy}; do 			case "$nope" in 				(.*) 					;; 				(*) 					echo "Acquire::http::proxy::${nope} \"DIRECT\";" >> /etc/apt/apt.conf.d/01proxy; 		echo "Acquire::https::proxy::${nope} \"DIRECT\";" >> /etc/apt/apt.conf.d/01proxy; 					;; 			esac; 		done; 		IFS="$oldIFS"; 	fi

setup_docker.sh is deprecated. For the recommended approach, please see: https://github.com/ValveSoftware/steam-runtime#using-docker

However, that won't necessarily solve your problem.

OCI runtime create failed: this version of runc doesn't work on cgroups v2: unknown

I would recommend trying a very simple Docker example, for example pulling and running https://hub.docker.com/_/hello-world. If that doesn't work either, report the problem to your distribution (Fedora).

If Fedora is actually using Podman instead of Docker, then running it unprivileged (without sudo) might be better?

@Dimitri2g Yeah, I haven't updated those wiki instructions in a long time… and I don't have time to get over them and fix it myself at the moment.

As for the problem at hand: it's most likely caused by Docker still not understanding cgroups v2, and this API was turned on by default in Fedora 31. There are two ways to fix it:

• Use podman instead of Docker. It's a Docker fork with issues like these fixed, it's included in Fedora repositories and should work as a drop-in replacement for docker.
• Force-disable cgroupsv2

Here's an article that seems to cover both options in detail

[Dimitri2g]

@smcv and @dreamer Thank you both for responding.

I will try to use podman and disable cgroupsv2

[dreamer]

@Dimitri2g With podman you won't need to disable cgroupsv2.
