I've just downloaded Ubuntu 16.04 and I'm trying to install PHP 7, but I keep getting the following error:

```
unable to locate package php7.0libapache2-mod-php7.0 

```

I tried running:

```
sudo apt-get update

```

and:

```
sudo apt-get install php7.0-mysql php7.0-curl php7.0-json php7.0-cgi  php7.0 libapache2-mod-php7.0

```

I've been searching for a while and cannot find a miracle to help.
