At some moment
autocomplete was broken
It was very useful to me to see packages name with Tab press
How to repair this autocomplete?
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
cp /etc/skel/.bashrc ~/
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.
Download the latest stable release from
./configure make sudo make install
if [ -f /etc/bash_completion ]; then . /etc/bash_completion fi
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/
