I downloaded the `.tar.gz` file on a Ubuntu 16.04.1 LTS machine, and `shasum` output OK. After unzipping the file and running `./bin/elasticsearch`, the following error happens:
```auto
[0.001s][warning][os,container] Duplicate cpuset controllers detected. Picking /sys/fs/cgroup/cpuset, skipping /run/lxcfs/controllers/cpuset.
Error: Could not find or load main class [0.001s][warning][os,container]
Caused by: java.lang.ClassNotFoundException: [0/001s][warning][os,container]
```
What should I do?

Hi,
Since ES 8.0, Ubuntu 16.04 is no more supported,you have to upgrade the ubuntu or use a compatible version.

Welcome to our community! 😃
You should also really use the deb packages for Ubuntu. It contains a bunch more than just the product binaries, such as service files, standardised config and logging etc.

Same issue for `elasticsearch-7.17.3`, which supports Ubuntu-16.04 on this page.

I think I just need the binaries for developing. Do I have to install that? Also where can I download those deb packages.

For developing what?
[Download Elasticsearch | Elastic](https://www.elastic.co/downloads/elasticsearch) is the download page for Elasticsearch.

I mean I have downloaded Elasticsearch. But I cannot set it up due to the above issue. Do I have to install the `deb packages for Ubuntu` as you mentioned?

You don't need to, no.
Is there more to your Elasticsearch logs?

Here is the `logs/gc.log`. I cannot find any other logs.

When you run the Elasticsearch binary it should output something to the shell.
