Package: steam Version: 1.0.0.52-4 Severity: important The steam browser (and hence the "Steam News" Popup at start) don't display anything. Looking at .steam/error.log, there are several lines pointing to a missing libXss:
~/.steam/ubuntu12_32/steamwebhelper: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory After installing libxss1:i386 manually the browser works again. So I suggest adding libxss1:i386 to the steam dependencies. -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (999, 'unstable'), (998, 'testing'), (990, 'stable'), (500, 'unstable-debug'), (500, 'testing-debug'), (350, 'experimental'), (1, 'experimental-debug') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.7.2-0 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages steam depends on: ii debconf [debconf-2.0] 1.5.59 ii libc6 2.23-5 ii libgl1-mesa-dri 12.1.0-0+devel-20160818.1406.own1 ii libgl1-mesa-glx 12.1.0-0+devel-20160818.1406.own1 ii libgpg-error0 1.24-1 ii libstdc++6 6.2.0-1 ii libtxc-dxtn-s2tc0 [libtxc-dxtn0] 0~git20131104-1.1 ii libudev1 231-5 ii libx11-6 2:1.6.3-1 ii libxinerama1 2:1.1.3-1+b1 ii xz-utils 5.1.1alpha+20120614-2.1 Versions of packages steam recommends: ii fonts-liberation 2.00.1-2 ii xterm [x-terminal-emulator] 325-1 ii zenity 3.20.0-1 Versions of packages steam suggests: pn steam-devices <none> -- debconf information: * steam/license: * steam/question: I AGREE steam/purge:
