Ubuntu 12.04 CT - procps upgrade fails

[MimCom]

Been bumping up against this on several Ubuntu 12.04 LTS containers

Setting up procps (1:3.2.8-11ubuntu6.1) ...
start: Job failed to start
invoke-rc.d: initscript procps, action "start" failed.
dpkg: error processing procps (--configure):
 subprocess installed post-installation script returned error exit status 1

Found a solution here that worked for me:

I just ran into the same issue. A simple workaround is to delete the file /etc/sysctl.d/10-kernel-hardening.conf

This has the rule: kernel.kptr_restrict = 1 which you can't do from an OpenVZ container.
