Please describe your issue in as much detail as possible:

I expect Portal 2 to launch inside of the Steam Linux Runtime Sniper. But Then I got a missing library that looks like is not in the debian repos, nor trying to compile to source worked.

Steps for reproducing this issue:

1. Generate the following Podman Image:

FROM debian:bookworm
USER root

RUN dpkg --add-architecture i386
RUN apt-get update
RUN apt-get dist-upgrade -y
RUN apt-get install -y --no-install-recommends ca-certificates
RUN apt-get install -y --no-install-recommends systemd systemd-sysv
RUN apt-get install -y --no-install-recommends coreutils
RUN apt-get install -y --no-install-recommends lsof
RUN apt-get install -y --no-install-recommends sudo
RUN apt-get install -y --no-install-recommends curl
RUN apt-get install -y --no-install-recommends lib32gcc-s1
RUN apt-get install -y --no-install-recommends libdrm2:i386 libgl1-mesa-glx:i386
RUN apt-get install -y --no-install-recommends pciutils
RUN apt-get install -y --no-install-recommends pkexec
RUN apt-get install -y --no-install-recommends dbus
RUN apt-get install -y --no-install-recommends dbus-x11

RUN echo >> /etc/sudoers && echo '%steam ALL = (ALL) NOPASSWD: ALL' >> /etc/sudoers
RUN rm /usr/bin/pkexec
RUN ln -s /usr/bin/sudo /usr/bin/pkexec
RUN echo 'root:root' | chpasswd

RUN curl -sqLO https://cdn.cloudflare.steamstatic.com/client/installer/steam.deb
RUN apt-get install -y ./steam.deb
RUN rm "steam.deb"

RUN mkdir /steam /data
RUN useradd steam -d /steam
RUN chown steam:steam /steam /data
WORKDIR /steam
USER steam

RUN curl -sqLO "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz"
RUN tar zxvf "steamcmd_linux.tar.gz"
RUN rm "steamcmd_linux.tar.gz"

USER root
RUN apt-get clean
RUN echo >> /etc/bash.bashrc
RUN echo export TERM=xterm-256color >> /etc/bash.bashrc
VOLUME [ "/sys/fs/cgroup", "/data" ]
CMD [ "/sbin/init" ]

2. Generate container with the following command: podman run -d --volume "${DIR}/steamdata:/data:rw" --tmpfs /tmp --tmpfs /run -v /sys/fs/cgroup:/sys/fs/cgroup:ro --volume "$XAUTHORITY:/steam/.Xauthority:rw" --volume /tmp/.X11-unix:/tmp/.X11-unix:ro --device /dev/kfd --device /dev/dri --userns keep-id -e "DISPLAY" --shm-size=1g --cap-add SYS_ADMIN --privileged --name "${CONTAINER_NAME}" "${IMAGE_NAME}"
   Where "${DIR}" is a directory of choice, configured such that ${DIR}/steamdata is case insensitive.
3. run the following steamcmd script in the container:

@ShutdownOnFailedCommand 1
force_install_dir /data/portal2
set_steam_guard_code AUTH_CODE
login USER_NAME
app_update 1628350 validate
app_update 620 validate
quit

4. Finally try to run podman exec -it CONTAINER_NAME /data/portal2/run-in-sniper --filesystem=/data/portal2 -- /data/portal2/portal2.sh where CONTAINE_NAME is the name given to the container
