我使用简单的 apt-get 命令安装了 octave，但后来不得不升级它。浏览了许多在线链接，我直接从网站下载了最新发布的文件并构建了它。但它开始出现许多错误，最终不得不清除并删除它。
之后，我使用稳定八度的存储库链接进行了全新安装。
sudo apt-add-repository ppa:octave/stable
sudo apt-get update
sudo apt-get install octave
但后来它开始出现以下错误：

最后，我找到了一个链接并解决了这个问题。
回复：在 ubuntu 14.04 上编译 Octave 4.0 时出错
我们需要在重新安装升级版本之前删除旧安装的 Octave 相关文件。然后要求 Ubuntu 继续之前的安装。
sudo rm -rf /usr/local/{bin,include,lib,libexec,share}/octave*
sudo rm -f /usr/local/bin/mkoctfile*
sudo apt-get -f install
