# Ubuntu Packages

Fluent Bit is distributed as **td-agent-bit** package and is available for the latest stable Ubuntu system: Xenial Xerus. This stable Fluent Bit distribution package is maintained by [Treasure Data, Inc](https://www.treasuredata.com).

## Server GPG key

The first step is to add our server GPG key to your keyring, on that way you can get our signed packages:

```
$ wget -qO - https://packages.fluentbit.io/fluentbit.key | sudo apt-key add -
```

## Update your sources lists

On Ubuntu, you need to add our APT server entry to your sources lists, please add the following content at bottom of your **/etc/apt/sources.list** file:

#### Ubuntu 18.04 LTS (Bionic Beaver)

```
deb https://packages.fluentbit.io/ubuntu/bionic bionic main
```

#### Ubuntu 16.04 LTS (Xenial Xerus)

```
deb https://packages.fluentbit.io/ubuntu/xenial xenial main
```

### Update your repositories database

Now let your system update the *apt* database:

```bash
$ sudo apt-get update
```

## Install TD-Agent Bit

Using the following *apt-get* command you are able now to install the latest *td-agent-bit*:

```
$ sudo apt-get install td-agent-bit
```

Now the following step is to instruct *systemd* to enable the service:

```bash
$ sudo service td-agent-bit start
```

If you do a status check, you should see a similar output like this:

```bash
sudo service td-agent-bit status
● td-agent-bit.service - TD Agent Bit
