Comment 19 for bug 447197

I think I am affected by this bug. Below is my sysctl.d output as requested and also the full error message from an apt-get upgrade:

This directory contains settings similar to those found in /etc/sysctl.conf.
In general, files in the 10-*.conf range come from the procps package and
serve as system defaults. Other packages install their files in the
30-*.conf range, to override system defaults. End-users can use 60-*.conf
and above, or use /etc/sysctl.conf directly, which overrides anything in
this directory.

After making any changes, please run "invoke-rc.d procps start".
