Failed to install mobz/elasticsearch-head in Ubuntu?

When I install Elasticsearch-head plugin with the command: plugin --install mobz/elasticsearch-head in Ubuntu, it show an error:
-> Installing mobz/elasticsearch-head...
Trying https://github.com/mobz/elasticsearch-head/archive/master.zip...
Failed to install mobz/elasticsearch-head, reason: failed to download out of all possible locations..., use --verbose to get detailed information


SOLUTION:

Run command: sudo apt-get update to update the package list in Ubuntu OS, and then try to setting elasticsearch-head again.
