# Install Latest Nginx Ubuntu Server

## Official Debian/Ubuntu packages

The available NGINX Ubuntu release support is listed at [this distribution page](https://nginx.org/packages/ubuntu/dists/). For a mapping of Ubuntu versions to release names, please visit the [Official Ubuntu Releases page](https://wiki.ubuntu.com/Releases).

Append the appropriate stanza to `/etc/apt/sources.list`. If there is concern about persistence of repository additions (i.e. DigitalOcean Droplets), the appropriate stanza may instead be added to a different list file under `/etc/apt/sources.list.d/`, such as `/etc/apt/sources.list.d/nginx.list`.

```bash
## Replace $release with your corresponding Ubuntu release.
deb https://nginx.org/packages/ubuntu/ $release nginx
deb-src https://nginx.org/packages/ubuntu/ $release nginx
```

e.g. Ubuntu 20.04 (Focal Fossa):

```bash
deb https://nginx.org/packages/ubuntu/ focal nginx
deb-src https://nginx.org/packages/ubuntu/ focal nginx
```

To install the packages, execute in your shell:

```bash
sudo apt update
sudo apt install nginx
```

If a `W: GPG error:` [`https://nginx.org/packages/ubuntu`](https://nginx.org/packages/ubuntu) `focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY $key` is encountered during the NGINX repository update, execute the following:

```bash
## Replace $key with the corresponding $key from your GPG error.
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys $key
sudo apt update
sudo apt install nginx
```

You have now nginx installed on your server but not ready to serve web pages. you have to start the nginx. You can do this by using this command:

```bash
sudo systemctl start nginx
```

# Ubuntu 22.04+

Install the prerequisites:

> ```bash
> sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring
> ```

Import an official nginx signing key so apt could verify the packages authenticity. Fetch the key:

> ```bash
> curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
>     | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
> ```

Verify that the downloaded file contains the proper key:

> ```bash
> gpg --dry-run --quiet --no-keyring --import --import-options import-show /usr/share/keyrings/nginx-archive-keyring.gpg
> ```

The output should contain the full fingerprint `573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62` as follows:

> ```bash
> pub   rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
>       573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62
> uid                      nginx signing key <signing-key@nginx.com>
> ```

If the fingerprint is different, remove the file.

To set up the apt repository for stable nginx packages, run the following command:

> ```bash
> echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
> http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
>     | sudo tee /etc/apt/sources.list.d/nginx.list
> ```

If you would like to use mainline nginx packages, run the following command instead:

> ```bash
> echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
> http://nginx.org/packages/mainline/ubuntu `lsb_release -cs` nginx" \
>     | sudo tee /etc/apt/sources.list.d/nginx.list
> ```

Set up repository pinning to prefer our packages over distribution-provided ones:

> ```bash
> echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
>     | sudo tee /etc/apt/preferences.d/99nginx
> ```

To install nginx, run the following commands:

> ```bash
> sudo apt update
> sudo apt install nginx
> ```
