Установите пакет Ubuntu, php7.0-sqlite3 пропавшие без вести

Ubuntu с php7

Ошибка происходит при попытке использовать SQLite3 от php:

PHP Fatal error:  Class 'SQLite3' not found in /var/www/html/index.php on line 1

Я попытался установить php7.0-sqlite3:

$ sudo apt-get install php7.0-sqlite3
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package php7.0-sqlite3
E: Couldn't find any package by regex 'php7.0-sqlite3'

По-видимому, пакет отсутствует:

$ sudo apt-cache search php7.0-*
php7.0-mysql - MySQL module for PHP
php7.0-readline - readline module for PHP
php7.0-opcache - Zend OpCache module for PHP
php7.0 - server-side, HTML-embedded scripting language (metapackage)

php7.0-cli - command-line interpreter for the PHP scripting language
php7.0-fpm - server-side, HTML-embedded scripting language (FPM-CGI binary)
php7.0-json - JSON module for PHP
