[Bug 1240332] Re: "procps" error caused by recent update to Ubuntu 12.04 (12.04.3)

[Andreas Gutlederer]

Workaround doesn't work for me but I'm able to change
/proc/sys/kernel/kptr_restrict:

# cat /proc/sys/kernel/kptr_restrict
1

# echo 2 > /proc/sys/kernel/kptr_restrict
# cat /proc/sys/kernel/kptr_restrict
2

Title:
  "procps" error caused by recent update to Ubuntu 12.04 (12.04.3)

Status in “procps” package in Ubuntu:
  Confirmed

Bug description:
  Recent updates on a typical Ubuntu 12.04 (12.04.3) LAMP server has
  errors relating to updates to the "procps" package.

  Apparently, /proc/sys/kernel/kptr_restrict is no longer editable, even by root,
  and is always set to "1", as confirmed by:      cat  /proc/sys/kernel/kptr_restrict

  Therefore, attempts to change it in /etc/sysctl.d/10-kernel-
  hardening.conf will fail.

  As a consequence of this, apt-get will complain with errors and the
  "procps" package will never finish being installed.

  - - - - -

  An effective workaround is to comment out this line:  (in the file: /etc/sysctl.d/10-kernel-hardening.conf )
  # kernel.kptr_restrict = 1

  And then run this command:   service procps restart
