Hi, Finally I updated my installation of Cin-GG on debian testing and debian 9 and encounter some problems. In debian testing Cin failed to start with shared libraries error: libva.so.1: cannot open shared object file: No such file or directory. These packages are installed libvdpau1, libvdpau-dev, libvdpau-va-gl1, libva2, libva-dev. And there no package containing libva.so.1 only libva.so.2(libva2) and libva.so(libva-dev). The package libva1 removed in upcoming debian release in favor of libva2 due to library version change. On debian 9 cin failed to install with folowing error: root@deurmods:~# LANG=C apt install cin Reading package lists... Done Building dependency tree Reading state information... Done cin is already the newest version (1:5.1.20190430). The following packages were automatically installed and are no longer required: libass5 libatomic1 libbdplus0 libbluray1 libebur128-1 libflite1 libopenal-data libopenal1 libopencv-core2.4v5 libopencv-imgproc2.4v5 libpgm-5.2-0 libsodium18 libssh-gcrypt-4 libtbb2 libtwolame0 libwavpack1 libwebpmux2 libzmq5 Use 'apt autoremove' to remove them. 0 upgraded, 0 newly installed, 0 to remove and 109 not upgraded. 1 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Do you want to continue? [Y/n] Setting up cin (1:5.1.20190430) ... dpkg: error processing package cin (--configure): subprocess installed post-installation script returned error exit status 255 Errors were encountered while processing: cin E: Sub-process /usr/bin/dpkg returned an error code (1) I investigate more and find following error during post install routine: sysctl: setting key "kernel.shmmax": Read-only file system sysctl: setting key "kernel.shmmni": Read-only file system I'm think that's happen because of lxc nature of my system. To set these values I have to use a privileged container. May be post install routine should check availability to set these values and instead of error throw warning message to user, that these values should be added manually.
