debian 环境安装
<p>debian使用apt簇命令是，会与dpkg联动进行软件安装，<code class="command">dpkg</code> 是安装 Debian 已经可用软件包的工具 (因为不需下载任何东西)。我们使用它的 <code class="literal">-i</code> 或 <code class="literal">--install</code> 选项</p><p><code class="command">dpkg</code> 是系统上处理 Debian 软件包的基础指令。如果有 <code class="filename">.deb</code> 软件包，那么可以用 <code class="command">dpkg</code> 来安装或分析其内容。但此指令只能看到 Debian 世界的部分内容：它知道系统安装了那些软件包，以及命令行给出了什么，但不知道其它还有哪些可用的软件包。这样，如果没有相依性就会失败。如 <code class="command">apt</code> 和 <code class="command">aptitude</code> 这样的工具，相反会可产生相依性清单，来尽量自动地安装软件包。</p>
<p>使用dpkg进行安装时需要下载软件包在/var/cache/下，后缀名为.deb文件。</p>
<p>然后使用dpkg -i 进行安装</p>

<p> 若，之前单独使用dpkg进行安装软件后，再使用apt-get命令安装依赖，会出现依赖信息报错，报错不影响，软件已安装完成，该抱错时告知软件安装包之间依赖异常；异常告警信息来源与oracle-java11-installer-local.postinst文件，可根据告警信息查询</p>
