Even wonder why alt-printscreen stops working some time ago? Apparently after a certain kernel version, the sysrq key is no longer bound by default. Re-enable it in sysctl.conf:
kernel.sysrq = 0

After a fresh install of 6.06, you'd probably want to run the followings to install the usual but missing stuff
# update your installation
apt-get update
# install kernel source
apt-get install kernel-image
# install kernel headers
apt-get install linux-headers-`uname -?`
# install development tools (e.g. gcc, make, etc.)
apt-get install build-essential

===if-up.d===
ok weird things about files in this directory. I added a script to set up txqueuelen but it was not ran or it's being overwritten. somehow, I changed ntpd to not run in the background (by removing & at the end) and that solved the problem. Perhaps runparts dies when it encounter an error or something. Anyway, that may also be why my nfs mounts are not brought up on boot because of files in this directory.

Additions:
===Skipping packages in update manager===
Open synaptic package manager, select upgradable packages, then go to package > lock version. Seems to me it's actually adding a regex to a file. The following contains packages I want to exclude (linux kernel).
# /etc/apt/apt.conf.d/05aptitude
aptitude::Keep-Unused-Pattern "^linux-image.*$ | ^linux-restricted-modules.*$ | ^linux-ubuntu-modules.*$";
aptitude::Get-Root-Command "sudo:/usr/bin/sudo";
