[standard] Autocomplete not working in bash in Ubuntu 19.04

Problem/Motivation

I tried to enable autocomplete on bash in Ubuntu 19.04. I was not able to get it working out of the box.

Also per the documentation in README.md the package http://bash-completion.alioth.debian.org/ is required. However this URL is not valid.

How to reproduce

I followed the instructions for installation as per the README.md and as per the messages in the install process.

• Drupal version - 8.7.7
• Console version - 1.9.3
• Console Launcher version - 1.9.3

More info

While sourcing console.rc separately I get this as well. Not sure if it is related

$ source ~/.console/console.rc 
                                           
  The "--learning" option does not exist.  
                                      
_completion [-g|--generate-hook] [-p|--program PROGRAM] [-m|--multiple] [--shell-type [SHELL-TYPE]] [-h|--help] [-q|--quiet] [-v|vv|vvv|--verbose] [-V|--version] [--ansi] [--no-ansi] [-n|--no-interaction] [--] <command>

$ echo $?
0
$ 

Solution

Will need to find and fix the issue.

Documentation Fixes

Looks like there has to be some fixes in the documentation as well. https://salsa.debian.org/debian/bash-completion seems to be the URL for the bash-completion project.

I have installed

$ composer require stecman/symfony-console-completion

I also have bash-completion installed in the system.

I was trying to debug this further

When I run the command inside a Drupal folder I get

$ drupal _completion -g -p drupal

When I run it outside the Drupal folder I get

$ drupal _completion -g -p drupal
