On April 23rd, I started seeing this on my ubuntu 14.04 system in an lxc guest: $ sudo /sbin/sysctl -p sysctl: setting key "kernel.sem": Read-only file system
Didn't we go through this last year? :-) http://comments.gmane.org/gmane.linux.kernel.containers.lxc.devel/7886 Back then, the symptom was different: sysctl: permission denied on key 'kernel.sem' So maybe this is a different problem. /var/log/apt/history.log says Start-Date: 2015-04-23 08:05:46 Commandline: aptdaemon role='role-commit-packages' sender=':1.780' Install: linux-headers-3.13.0-49-generic:amd64 (3.13.0-49.83), lxcfs:amd64 (0.7-0ubuntu4~ubuntu14.04.1~ppa1), linux-headers-3.13.0-49:amd64 (3.13.0-49.83)...
