  <title>安装额外的应用程序</title>

  <p>
    An application is software that has a graphical user interface (GUI).
    The Ubuntu development team has chosen a default set of applications that we 
    think makes Ubuntu very useful for most day-to-day tasks. However, you will 
    certainly want to install more applications to make Ubuntu more useful to you.
    To install an application, you can use <app>App Center</app>.
   </p>

   <p>应用程序有两种格式：snap 软件包和 Debian 软件包。现在可作为 snap 软件包使用的应用程序称为 <em>snap</em>。一些应用程序同时具有这两种格式。在这种情况下， <app>App Center</app> 将会优先列出 snap 软件包。</p>

   <p>您可能还希望安装没有图形窗口的软件，要安装此类软件，您可以使用 <link xref="addremove-install-synaptic">新立得</link>。 请注意，<app>新立得</app>不会列出快照。</p>

  <p>安装一个应用程序：</p>

  <steps>
    <item>
      <p>
        Click the <app>App Center</app> icon in the <gui>Dock</gui>, or search
        for <input>Software</input> in the <em>Activities</em> search bar.
      </p>
    </item>
    <item>
      <p>
        When <app>App Center</app> launches, search for an application, or select 
        a category and find an application from the list.
      </p>
    </item>
    <item>
      <p>选择要安装的应用程序，然后单击<gui>安装</gui>。</p>
    </item>
    <item>
      <p>输入管理员密码，验证通过后，开始安装。安装通常会很快完成，但是如果您的 Internet 连接速度较慢，则可能需要等待一段时间。</p>
