Ubuntu 15.04: Elasticsearch service doesn't start

I followed the first part from the tutorial here to install Elasticsearch. I didn't install java because I already have that installed with other java programs running.

sudo service elasticsearch restart

Doesn't output anything.

sudo service elasticsearch status

Outputs the following:

● elasticsearch.service - Starts and stops a single elasticsearch instance on this system Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: enabled) Active: failed (Result: exit-code) since Sat 2015-06-06 08:33:20 EET; 1s ago Docs: http://www.elasticsearch.org Process: 17111 ExecStart=/usr/share/elasticsearch/bin/elasticsearch -Des.default.config=$CONF_FILE -Des.default.path.home=$ES_HOME -Des.default.path.logs=$LOG_DIR -Des.default.path.data=$DATA_DIR -Des.default.path.work=$WORK_DIR -Des.default.path.conf=$CONF_DIR (code=exited, status=3) Main PID: 17111 (code=exited, status=3)

It says I should pass -l option somewhere to get the full output though I don't know where exactly.

This is a known issue with Elasticsearch on Ubuntu 15.04. There is a GitHub issue. The temporary fix:

As a workaround you can uncomment the paths in the /etc/default/elasticsearch file and it should work.
