Please edit your question to add more information. What does it do now when you press tab? Is there an error? Please include it.– Oli ♦Dec 9, 2011 at 10:21

For example I press tab after sudo apt-get install ruby, and terminal display me all packages with ruby: ruby-mysql, ryby-dev, etc.– Вячеслав ЛогиновDec 9, 2011 at 11:51

As stated in the comments to the other answer, first make sure that bash-completion is installed:
sudo apt-get install bash-completion
and apparently for @diapir, it helped to reinstall it:
sudo apt-get install --reinstall bash-completion
However, for me, the problem was not that bash-completion was not installed or broken, the problem was that I had accidently deleted my .bashrc file. You can get a new one by copying it from /etc/skel:
cp /etc/skel/.bashrc ~/

2Thanks, the bashrc tip solved the problem for me as well. The use of
sudoon thechmodcommand is unnecessary though, right? Dec 24, 2012 at 4:32 -
2the file located in
/etc/is0644/-rw-r--r--with user:group =root:root, and when copied to your user folder, will automatically go to user:user– KevinMay 28, 2014 at 17:07 -

I just needed to reinstall bash-completion after upgrading from Debian 9 to Debian 10 Aug 10, 2021 at 21:13
Type the following command:
sudo -H gedit /etc/bash.bashrc
Look for these lines:
# enable bash completion in interactive shells
# if ! shopt -oq posix; then
# if [ -f /usr/share/bash-completion/bash_completion ]; then
# . /usr/share/bash-completion/bash_completion
# elif [ -f /etc/bash_completion ]; then
# . /etc/bash_completion
# fi
# fi
Uncomment some lines, to make it look like this:
# enable bash completion in interactive shells
if ! shopt -oq posix; then
if [ -f /usr/share/bash-completion/bash_completion ]; then
. /usr/share/bash-completion/bash_completion
elif [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
fi
Save, close terminal, then reopen it.
I have this issue after installing 13.04, and that's how I resolve it.
Note that output of this command:
apt-config dump | grep "Dir::Cache"
Should be something like this:
Dir::Cache "var/cache/apt";
Dir::Cache::archives "archives/";
Dir::Cache::srcpkgcache "srcpkgcache.bin";
Dir::Cache::pkgcache "pkgcache.bin";
If value of Dir::Cache::pkgcache is empty, apt will not be able to auto complete package names. Take a look at your /etc/apt/apt.conf.d/ files and search for this key to be sure that it's not set to empty string.
grep -r pkgcache /etc/apt/apt.conf.d/
Also take a look at this answer.

3Looks like this (and the link) is the correct answer if you have this issue inside a docker container. Feb 24, 2020 at 14:00

rm /etc/apt/apt.conf.d/docker-cleanFeb 14, 2021 at 15:45
Download the latest stable release from http://bash-completion.alioth.debian.org/
./configure
make
sudo make install
insert
if [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
to ~/.bashrc

bash-completionis in packages - is there any reason you did it manually? The package should do pretty much exactly this :)– CaesiumDec 10, 2011 at 12:46 -
:) as always, sitting, reading manuals, configure, and then it turns out that this soft is exists in the repository Dec 10, 2011 at 12:57
