Auto Complete Bash not Responding with Sudo
sudo nano /etc/bash.bashrc and look for the following:
# enable bash completion in interactive shells lost its color
if [ -f /etc/bash_completion ]; then
. /etc/bash_completion
fi
Take out the # and restart bash. If this doesn’t solve your issue, the replace this your own bashrc file with this one: BASHRC. Or if you don’t have one, add this to your /home/USER/ directory. Make sure you rename it to .bashrc
