Drush installation issue I am trying to install the most uptodate version of Drush as I begin working on Drupal 8.

Apt-get only installs Drush version 5.10.0. So, I'm attempting to install Drush via composer with the following effect:

sisko@li184-76:~$ composer global require drush/drush:dev-master
Changed current directory to /home/sisko/.composer
The "fxp/composer-asset-plugin" plugin was skipped because it requires a Plugin API version ("1.0.0") that does not match your Composer installation ("1.1.0"). You may need to run composer update with the "--no-plugins" option.
./composer.json has been updated

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for drush/drush dev-master -&gt; satisfiable by drush/drush[dev-master].
    - drush/drush dev-master requires consolidation/robo dev-master -&gt; satisfiable by consolidation/robo[dev-master] but these conflict with your requirements or minimum-stability.
  Problem 2
    - fxp/composer-asset-plugin v1.0.0 requires composer-plugin-api 1.0.0 -&gt; no matching package found.
    - fxp/composer-asset-plugin v1.0.0 requires composer-plugin-api 1.0.0 -&gt; no matching package found.
    - fxp/composer-asset-plugin v1.0.0 requires composer-plugin-api 1.0.0 -&gt; no matching package found.
    - Installation request for fxp/composer-asset-plugin 1.0.0 -&gt; satisfiable by fxp/composer-asset-plugin[v1.0.0].

Potential causes:
 - A typo in the package name
 - The package is not available in a stable-enough version according to your minimum-stability setting
   see &lt;https://getcomposer.org/doc/04-schema.md#minimum-stability&gt; for more details.

Installation failed, reverting ./composer.json to its original content.
sisko@li184-76:~$ drush status
The program 'drush' is currently not installed. You can install it by typing:
sudo apt-get install drush
sisko@li184-76:~$


Can anyone please help me out?
If you want to install Drush via composer require rather than git clone followed by composer install (which is slightly easier), then I would recommend:


Use the stable version of Drush, ~8
Install with cgr
