# ROS 软件仓库镜像使用帮助

<form class="form-inline">
<div class="form-group">
	<label>是否使用 HTTPS</label>
	<select id="http-select" class="form-control content-select" data-target="#content-0,#content-1">
	  <option data-http_protocol="https://" selected>是</option>
	  <option data-http_protocol="http://">否</option>
	</select>
</div>
</form>


<form class="form-inline">
<div class="form-group">
	<label>是否使用 sudo</label>
	<select id="sudo-select" class="form-control content-select" data-target="#content-0,#content-1">
	  <option data-sudo="sudo " selected>是</option>
	  <option data-sudo="">否</option>
	</select>
</div>
</form>



新建 `/etc/apt/sources.list.d/ros-latest.list`，内容为：



<form class="form-inline">
<div class="form-group">
  <label>发行版：</label>
    <select id="select-0-0" class="form-control content-select" data-target="#content-0">
      <option data-release_name="focal" selected>Ubuntu 20.04 LTS</option>
      <option data-release_name="bionic">Ubuntu 18.04 LTS</option>
      <option data-release_name="xenial">Ubuntu 16.04 LTS</option>
      <option data-release_name="trusty">Ubuntu 14.04 LTS</option>
      <option data-release_name="buster">Debian 10</option>
      <option data-release_name="stretch">Debian 9</option>
      <option data-release_name="jessie">Debian 8</option>
    </select>
</div>
</form>

{% raw %}
<script id="template-0" type="x-tmpl-markup">
deb {{http_protocol}}{{mirror}}/ubuntu/ {{release_name}} main
</script>
{% endraw %}

<p></p>

<pre>
<code id="content-0" data-template="#template-0" data-select="#http-select,#sudo-select,#select-0-0">
</code>
</pre>


然后再输入如下命令，信任 ROS 的 GPG Key，并更新索引：



{% raw %}
<script id="template-1" type="x-tmpl-markup">
{{sudo}}apt-key adv --keyserver 'hkp://keyserver.ubuntu.com:80' --recv-key C1CF6E31E6BADE8868B172B4F42ED6FBAB17C654
{{sudo}}apt update
</script>
{% endraw %}

<p></p>

<pre>
<code id="content-1" data-template="#template-1" data-select="#http-select,#sudo-select">
</code>
</pre>
