Your /etc/bash_completion file must be missing.
sudo apt-get install bash-completion
should solve all your problems.
Given that you already have lines uncommented in /etc/bash.bashrc as Faheem Mitha and others pointed out, it should work now:
# enable bash completion in interactive shells
if [ -f /etc/bash_completion ] && ! shopt -oq posix; then
. /etc/bash_completion
fi
Reason: The bash-completion package now has that file (/etc/bash_completion).
It used to be in the bash package, but not any more.
info on package change
Starting from @derobert's answer, I worked my way to getting exactly the current version of all packages to reinstall.
Short version:
sudo dpkg -l | grep '^ii ' | sed 's/ */\t/g' |cut -f 2,3 | sed 's/\t/=/' | xargs apt-get install --reinstall -y --ignore-missing
Explained:
The key is actually specifying the required version of each package.
The general command is:
apt-get install --reinstall <package>=<version>
Breaking down the long command line:
$ dpkg -l
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Architecture Description
+++-===========================================================-==================================-============-========================================================================
ii adduser 3.113+nmu3 all add and remove users and groups
ii apt 0.9.7.8+rpi1 armhf commandline package manager
ii apt-utils 0.9.7.8+rpi1 armhf package managment related utility programs
ii aptitude-common 0.6.8.2-1 all architecture indepedent files for the aptitude package manager
ii atmel-firmware 1.3-4 all Firmware for Atmel at76c50x wireless networking chips.
$ dpkg -l | grep '^ii '
...gets rid of the header lines and a few packages with status 'hold' (marked as hi instead of ii)
$ dpkg -l | grep '^ii ' | sed 's/ */\t/g'
... converts any number of spaces to a single TAB character, preparing the ground for cut.
(Btw: why, oh why, doesn't sed support x+ regex for "character x, one or more times"? It can be emulated with xx* - meaning 'x' once followed by 'x' zero or more times)
The output looks like this:
ii adduser 3.113+nmu3 all add and remove users and groups
ii apt 0.9.7.8+rpi1 armhf commandline package manager
ii apt-utils 0.9.7.8+rpi1 armhf package managment related utility programs
ii aptitude-common 0.6.8.2-1 all architecture indepedent files for the aptitude package manager
ii atmel-firmware 1.3-4 all Firmware for Atmel at76c50x wireless networking chips.
Next:
$ dpkg -l | grep '^ii ' | sed 's/ */\t/g' | cut -f 2,3 | sed 's/\t/=/'
...gets the name and version of each package (the 2nd and 3rd fields), and replaces the tab that separates them with an '='
adduser=3.113+nmu3
apt=0.9.7.8+rpi1
apt-utils=0.9.7.8+rpi1
aptitude-common=0.6.8.2-1
atmel-firmware=1.3-4
Finally, pipe each of the above to apt-get as a long list of arguments using xargs.
Notice the parameter --ignore-missing - this command is run as 'best effort' - I don't want the updating to stop because some packages are not available to reinstall (those will stay unmodified)
$ dpkg -l | grep '^ii ' | sed 's/ */\t/g' |cut -f 2,3 | sed 's/\t/=/' | xargs apt-get install --reinstall --ignore-missing
While testing, I also added a --dry-run argument to apt-get.

means that you need to install the
man-dbpackage.Manpages are installed by default in most cases, because Debian policy strongly encourages them to be shipped in the same package as the commands themselves:
