sudo apt-get install … texinfo sudo apt-get install ... texinfo

Why do you want to install texinfo at all?为什么要安装 texinfo？ It's not required by nodejs and npm. nodejs 和 npm 不需要它。

Also, why on Earth are you installing stuff in an unsupported 5-years-old operating system?另外，你到底为什么要在一个不受支持的 5 年前的操作系统中安装东西？ Even LTS versions of Ubuntu should be upgraded to the next LTS version, or you will incur in incompatibilities sooner or later.即使是 Ubuntu 的 LTS 版本也应该升级到下一个 LTS 版本，否则迟早会导致不兼容。 Ubuntu 16.04 has not been maintained since more than 1 year ago. Ubuntu 16.04 已经1年多没有维护了。
